services laboratory microbiology ozone filtration oak processing aids enzymes nutrients ml bacteria yeast New Dynamic in Wine Fermentation Non-Saccharomyces Yeast for Flavor, Aroma and Tactile Development Wine fermentation practices have evolved greatly through the years as our understanding of grape and must ecology, microbial physiology and biochemistry continues to develop. Fermentation was once thought of as a one-stage process, primarily focused on sugar to alcohol conversion. As our understanding and appreciation of malolactic bacteria grew, fermentation practices evolved into two stages sugar to alcohol and malic to lactic conversion each stage with its own unique contribution to the organoleptic profile of the wine. With the commercialization of non-saccharomyces yeast, yet another dynamic shift in fermentation practices is occurring. Today s progressive winemakers are creating complex and multi-dimensional wines on a consistent basis by managing their fermentation regime in three stages flavor, aroma and tactile development with non- Saccharomyces yeast, followed by sugar to alcohol conversion with Saccharomyces yeast, and malic to lactic conversion with malolactic bacteria. Chr. Hansen led the charge in the development of non-saccharomyces yeast strains with the creation of their screening and selection programs over a decade ago. Since then, three pure commercial strains, and three mixed culture preparations have become widely utilized in winemaking and are known for the exceptional impact they make to wine quality. Pure non-saccharomyces yeast FrootZen TM 100% Pichia kluyveri First commercial direct inoculum frozen yeast Releases and converts odorless bound precursors into volatile aromatic thiols Concerto TM 100% Lachancea thermotolerans* Increases total acidity of wine (lactic acid formation) Integrated red and black fruit, spice *Formerly Kluyveromyces thermotolerans Prelude TM 100% Torulaspora delbrueckii Controlled inoculum helps minimize VA production Heavy producer of polysaccharides For wines matured in oak, bridges gap between yeast derived compounds and oak flavors 4 2017-2018 Gusmer Enterprises, Inc. Wine Products Catalog Mixed Culture Blends Melody TM 60% S. cerevisiae, 20% L. thermotolerans, 20% T. delbrueckii Selected for enhancing exotic fruit and stone fruit flavors in complex wine such as Chardonnay, Viognier, and delicate white and red wines Harmony 80% S. cerevisiae, 10% L. thermotolerans, 10% T. delbrueckii Excellent choice for elegant wines with sweet and intense fruit, and enhances mouthfeel and palate weight Rhythm 60% S. cerevisiae, 40% L. thermotolerans Produces aromatic red wines rich in blackberry and blackcurrant flavors, and preserves the acidity in wine Non-Saccharomyces yeast require a lower rehydration temperature. It is important to follow package instructions for Non-Saccharomyces yeast rehydration.

Non-Saccharomyces (continued) Culture Strains Three Stages of Fermentation Flavor Aroma Modification *Simultaneous Inoculation In a simultaneous inoculation, the non-saccharomyces and Saccharomyces yeast are added at the same time (as with Chr. Hansen s mixed culture blends). The non-saccharomyces yeast is active during the lag/log phase of the Saccharomyces yeast, thus bio-protecting the wine and developing flavor, aroma and mouthfeel. As the Saccharomyces population becomes established, and the alcohol level increases and oxygen level decreases, the non-saccharomyces population is quickly dominated and the fermentation is driven to completion by the Saccharomyces yeast. **Sequential Inoculation FERMENTATION STAGE Alcoholic Fermentation Malolactic Fermentation Day 1 to 3 Day 4 to 7 Day 8 to 21 Non-Saccharomyces Chr.

Hansen Vinaflora Oenos Vinaflora Oenos 2.0 Vinaflora CH11 Vinaflora CH16 Vinaflora CH35 Vinaflora CiNe Malolactic Bacteria In a sequential inoculation, non-saccharomyces yeast are added to the must either during cold soak or at the onset of primary fermentation. During this early phase (which typically lasts one to three days or one to two degrees drop in Brix), the non-saccharomyces yeast dominate the yeast population, thus bio-protecting the wine by outcompeting potential undesirable indigenous strains. It is also during this time that the non-saccharomyces yeast contribute greatly to flavor, aroma and mouthfeel of the wine. Subsequent inoculation with your favorite Saccharomyces yeast quickly suppresses the non-saccharomyces yeast and drives the fermentation to completion. I ve been using Gusmer products for winemaking in the past 8 or 9 years. In the past 5 years I ve only used Chr. Hansen yeasts and my wines have gone from very good to outstanding, I think that is the reason my wines sell out every year. Thanks for the great products that you supply the wine industry.

services laboratory microbiology ozone filtration oak processing aids enzymes nutrients ml bacteria yeast Chr. Hansen FrootZen TM Viniflora Frootzen is the first commercial yeast preparation based on a pure strain of Pichia kluyveri. This non-saccharomyces yeast strain is specifically noted for its ability to enhance tropical fruit intensity and mouthfeel in white wines such as Sauvignon Blanc, Chardonnay, Riesling and fruit forward rosé and red wines. FrootZen is an extremely powerful producer of the volatile thiol aromas 3-MHA (passion fruit) and 3-MH (grapefruit), and significantly boosts flavor compounds such as peach, citrus and mineral. Since its launch in 2011, it has been widely adopted into wine programs in North America, New Zealand, France, Spain and other regions known for bright, aromatic wines. Use FrootZen with your favorite Saccharomyces 0 yeast in a sequential inoculation. Known as the quiet Saccharomyces only FrootZen + Saccharomyces fermenter, this strain of Pichia kluyveri does not create noticeable amounts of CO2, and a treated tank will appear to be very still. However, the fermentation is still progressing as evident by the noticeable increase in fruit aromas associated with the yeast and the 1-3 degree drop in brix over a three-day period. After FrootZen has done its job, inoculate with the Saccharomyces of choice to complete the fermentation. FrootZen is also the first commercial yeast preparation for winemakers which is meant for direct inoculation into grape juice frozen so no rehydration is required. Chr. Hansen has developed the technology to freeze yeast and offer it as a fully hydrated, direct inoculation product. It comes in 500g packages, and is delivered to your winery on dry ice. It can be stored for a short time on dry ice until used, or for longer term storage, in a -40 C freezer. 6 2017-2018 Gusmer Enterprises, Inc.

I ve been using the wild yeast mixed cultures for a number of years and tried the Pichia culture this year for the first time as a pre-fermentation pitch on a Napa Valley Sauvignon Blanc. The aromatic intensity this inoculation gave to the overall blend was amazing and I plan on continuing to use it as well as the other mixed cultures in the future.

What Chardonnay Style Are You? The exciting thing about Chardonnay is its ability to accommodate so many styles, allowing for a great degree of latitude in expression on the part of the winemaker. Unlike any other grape, Chardonnay can be graceful and elegant, light and fruity, or serious and provocative. Hugely malleable, it comes in many shapes and forms. In his report* on Chardonnay, Christian Eedes sums up well the five faces of Chardonnay (see chart below). Grape quality and oak are instrumental in shaping the final outcome of great Chardonnay Style programs, as is the management of both alcoholic and malolactic fermentations. The Chr. Hansen non-saccharomyces and Saccharomyces yeast and malolactic bacteria selections provide winemakers with the ability to form Chardonnay into what is required to define and differentiate programs, offering tools to accentuate full fruit expression, or complexity through diacetyl production, or somewhere in between. These same tools are easily applied to other grape varieties, but Chardonnay does it so well.

services laboratory microbiology ozone filtration oak processing aids enzymes nutrients ml bacteria yeast Renaissance Yeast Yeast with Purpose Renaissance Yeast is a research and development oriented company in Vancouver, Canada that is dedicated to developing premium yeast strains that address some of the wine industry s most important fermentation challenges. Since 2013, Renaissance Yeast has operated on the premise that fermentation problems can be addressed with yeast strain screening and development through natural breeding techniques. Novel Hydrogen Sulfide Related Discovery Through research funded by the American Vineyard Foundation, Dr. Linda Bisson (University of California, Davis) and her team revealed that the level of sulfide produced by yeast strains varies and that it is difficult to predict strain behavior in response to nitrogen supplementation. Hydrogen sulfide is one of several common sensory defects in wine. Most commercial wine yeast strains produce some amount of hydrogen sulfide, with levels topping out at 290 mg/l. The threshold level for human detection is 11 ng/l. Hydrogen sulfide can impart notes of rotten egg, garlic and burnt rubber, and if left untreated, can complex into other volatile sulfides such as disulfides and mercaptans. Dr. Bisson s research resulted in the isolation of the yeast strain UCD932 from a vineyard in Italy, and the understanding that this yeast strain is naturally unable to produce hydrogen sulfide in grape must. This novel discovery lead to extensive screening and crossbreeding programs by the research staff at Renaissance Yeast, and resulted in an innovative approach to preventing hydrogen sulfide in fermentations. Premium Yeast Delivering Superior Quality Renaissance Yeast has developed a new family of premium wine yeast strains that have excellent fermentation kinetics and organoleptic characteristics, and a natural inability to produce hydrogen sulfide in grape musts... all of the attributes that are so important to today s winemakers plus the natural prevention of hydrogen sulfide. These yeast strains are produced to the highest quality standards and are offered at price levels equivalent to commercial premium yeast strains. They offer valuable cost and time benefits, and allow for the production of higher quality wines. Hydrogen sulfide is produced by most strains of Saccharomyces during fermentation - even if at trace amounts, below the sensory threshold level. The effects of hydrogen sulfide are obvious at higher levels, but at levels below sensory threshold, CLICK IMAGE TO VIEW VIDEO 8 2017-2018 Gusmer Enterprises, Inc.

Renaissance Yeast (continued) hydrogen sulfide leads to closed or masked wines hindering the full expression of flavor and aroma compounds. In contrast, wines are much more open and bright when trace amounts of hydrogen sulfide are not present. Traditional sulfide remediation techniques, such as copper addition and aeration, have their own negative effect on overall wine quality. By preventing hydrogen sulfide formation during fermentation, Renaissance wine yeast helps to make good wines great and great wines amazing with full expression of flavor and aroma. Yeast Developed by Classical Breeding, Non-GMO Renaissance Yeast uses classical breeding techniques to develop its strains, not genetic modification. The strains are certified non-gmo. By inducing sporulation and sexual mating, selected yeast strains are crossbred and backcrossed repeatedly until the progeny strains have the desired characteristics of the parent strains. *Viva TM Ideal for artisan-style sparkling wines, fruit forward grape wines and fruit wines Strong fermentation kinetics, all the while preserving fresh, fruit character A rapid, clean fermenter characterized by its ability to work under diverse conditions Allegro TM Imparts good mid-palate fullness with color and flavor stability across all varietals Produces an intense fruit overture followed by a mild spiciness and a smooth tannin finish Ferments at a moderate tempo and performs well in medium nitrogen musts *Avante TM A versatile and reliable yeast for making red wines Produces an intense red fruit overture for color and flavor stability Maintains desired varietal characteristics with great aromas and flavors 2n 2n Sporulation Strain X n n *Muse TM * Product name change, contact your Gusmer sales representative for more information.

Hansen Malolactic Bacteria Cultures World Leader in Bacterial Cultures for the Wine Industry One of Chr. Hansen s core competencies is microbial physiology. By investigating how bacterial cultures interact with their environment, valuable insight is gained into strain functionality and performance. As the world leader in bacterial cultures for the food industries, Chr. Hansen has committed R&D and advanced production resources to providing the best malolactic bacterial cultures to the wine industry. That is evident by the fact that Chr. Hansen Viniflora cultures are the most widely used malolactic cultures. Reliable and predictable, Viniflora bacteria cultures are trusted by more winemakers worldwide to get their wines through malolactic fermentation on time and with desirable organoleptic outcomes. Not all strains of Oenococcus oeni are the same, nor are all malolactic bacterial preparations. Some strains are more tolerant to environmental parameters such as ph, temperature, sulfur dioxide and alcohol. That tolerance depends partly on the natural capabilities of the strain, but more importantly on a production process that properly adapts the cell to enter the harsh environment of wine. It takes properly conditioned cells to survive the freeze drying process, and the ultimate inoculation into wine, to assure a high degree of cell viability. Chr. Hansen preparations are not only tested for viability, but each batch of bacteria is also tested for the cell s ability to convert malic acid to lactic acid. Only Chr. Hansen uses this MACC test (Malic Acid Conversion Capacity) as a quality control parameter for each batch produced. 12 2017-2018 Gusmer Enterprises, Inc. Wine Products Catalog

Following this latest research, Chr. Hansen now delivers the cinnamoyl esterase profile for each and every strain commercialized. This information may help winemakers select the strain of malolactic culture they want to use in regards to the type of wine produced. Chr. Hansen recommends the following cinnamoyl esterase negative strains for barrel aged wines -Vinoflora CH16, CH11, CH35 or Oenos 2.0. Cinnamoyl esterase positive strains, Vinoflora Oenos and CiNe, are recommended for white wines (to avoid oxidation) and red wines (to stabilize color) that do not mature in barrels.

Application Notes for Malolactic Bacteria The rate of the malolactic fermentation, and ultimately, the success of the fermentation, are dependant on several key factors the level of inoculation, the strain of bacteria used and the parameters of the wine. Level of Inoculation The Magic Number It is frequently observed that efficient malolactic fermentations require a minimum cell density of approximately 10 6 CFU/ml one million cells per milliliter the magic number. Malic acid conversion has also been found to be proportional to cell density; so the more cells above one million per milliliter, the faster the malolactic fermentation will progress. This means that a pouch of bacteria used to inoculate 660 gallons must contain at least 2.5x10 12 viable cells in order to ensure an inoculation level of 10 6 CFU/ml, and all of those cells must survive inoculation into the wine. Not all commercial preparations contain this level of viable cells, nor do all manufacturers prepare the cells to survive the inoculation. Chr. Hansen not only checks its Viniflora cultures to assure that their cell numbers exceed these levels, but also checks the cells ability to survive inoculation and convert malic acid. Stretching the Cultures Stretching the cultures by inoculating volumes of wine greater than what is recommended is not always prudent. Stretching means that the inoculation rates of the Oenococcus oeni may fall below 10 6 CFU/ml and that a malolactic fermentation with the desirable bacteria may not start until cells go through sufficient generations. Oenococcus oeni is a slowgrowing organism and can be outcompeted by other, undesirable bacteria (Lactobacillus, Pediococcus, etc.). Ultimately the quality of the wine can be affected, and at the very least the fermentation will be drawn out by days, weeks, or possibly months, tying up tank space, requiring ongoing monitoring, and enduring unnecessary risk of oxidation and spoilage. Strain of Bacteria Different strains of Oenococcus oeni have different fermentation characteristics and different abilities to survive the extreme conditions of wine. The characteristics and survivability are determined by the strains natural capabilities and the skill used in preparing the cultures to adapt. Chr. Hansen is the world s leader in bacteria preparations for food cultures, with a wide-ranging strain bank and extensive expertise. The Viniflora strains were selected and adapted specifically to meet the varied wine parameters and the high standards of winemakers. Wine Parameters SO 2, ph, alcohol and temperature are the key wine parameters to consider for successful malolactic fermentations. Any one of these parameters outside the bacteria s limitations can slow down or inhibit the fermentation. It is important to remember that these parameters all work in concert with one another and together have a synergistic effect on the bacteria. Exceeding the limitations for one parameter, if others are in line, may be less restrictive than three or four parameters that are high but within the limitations for the strain. SO 2 Be aware of the toxic effect of SO 2 on malolactic bacteria and keep the addition to a minimum. In general, lower is better, with the maximum TSO 2 at 30-70 ppm depending on the strain of bacteria and the type of wine (see chart on page 16). Some strains of yeast (especially Saccharomyces bayanus) produce high levels of SO 2 during alcoholic fermentation. Choosing an ML-friendly strain of yeast, which produces minimal amounts of SO 2, will help to assure the success of your malolactic fermentation.

services laboratory microbiology ozone filtration oak processing aids enzymes nutrients ml bacteria yeast Application Notes for Malolactic Bacteria (continued) ph Lower ph levels create more challenging conditions for malolactic fermentations. Some Viniflora strains can handle ph levels down to 3.3, and under certain conditions down to 3.1. The CH35 and CH11 strains were selected to handle lower ph levels, and under certain conditions, can go down to 3.0. High ph can be a challenge as well in that both desirable and undesirable bacteria find it easier to thrive. High ph values usually dictate the need for a strong inoculation of Oenococcus oeni to outcompete the undesirable bacteria. Alcohol High levels of alcohol have an inhibitory effect on bacteria. In general, the Viniflora strains can handle up to 14% alcohol, with the CH16 strain being especially selected for high alcohol red wines (up to 16%). Chr.

Wine Products Catalog Temperature In wine, the optimal temperature for malolactic fermentation is 63-72 F, with the maximum temperature around 77 F. Temperatures below 50 F will slow the metabolism of malic acid to the point that the fermentation is significantly delayed. Low temperatures in the wine do not necessarily kill the cells, but under most conditions, make them dormant. In most cases, if all parameters are good, the fermentation can be restarted by heating the wine to optimal temperatures. Temperatures above 77 F can kill Oenococcus oeni. Storage Chr.

Gusmer Enterprises MicroEssentials TM Nutrients Gusmer s MicroEssentials fermentation nutrients include a complete range of supplements for yeast rehydration, primary fermentation and malolactic fermentation. MicroEssentials nutrient formulations incorporate findings from the latest research and are based on premium ingredients. Our complex supplements contain highly refined polypeptides and amino acids, and a full spectrum of essential vitamins, minerals and yeast survival factors for a rich source of compounds that are highly assimilable by yeast and bacteria. These nutrients comply fully with the TTB regulations and are produced locally in our own facility, under GMP conditions. Used to support cell growth, general metabolism, protein synthesis and alcohol tolerance, fermentation nutrients contribute greatly to healthy fermentations and help guard against the formation of hydrogen sulfide and other unwanted metabolites. Gusmer s MicroEssentials nutrients are designed to fit any wine production protocol. Nutrients for Yeast MicroEssentials Prime yeast rehydration nutrient provides assimilable organic nitrogen and micronutrients. The addition of bioavailable nutrients during yeast rehydration helps to ensure survival during the stressful transition of inoculation. Studies comparing MicroEssentials Prime to other yeast rehydration nutrients show MicroEssentials Prime to provide a healthier and faster fermentation -- even at a lower dose rate. MicroEssentials Powder is a full spectrum nutrient blend in powdered form, which is dosed into the must during inoculation, and as required during alcoholic fermentation. It is recommended for use in both red and white wine fermentations when juice analysis shows low levels of YAN or when fermentation conditions prove challenging. MicroEssentials Trace is a pure vitamin and mineral complex, used to supplement other yeast nutrients when additional micronutrients are required. Time-Release Nutrients for Yeast Winemakers commonly make incremental additions of nutrients during the first half of the fermentation as a means to manage the fermentation rate through the quantity and composition of available nutrients. The nutrient demand is greatest during the exponential phase, when cells require more organic nitrogen rich compounds to reach the desired level of biomass. This leaves limited nutrients available for subsequent generations of yeast to maintain the biomass through to the end of fermentation. Incremental addition assures nutrient availability to these later generations of yeast. The MicroEssentials Complete-TR and MicroEssentials Boost-TR were developed as a solution to the logistical difficulties of incremental additions. Nutrients are compressed into tablets creating a distinct time-release profile, delivering the proper dose and composition of nutrients as needed throughout the fermentation -- but with a single addition. MicroEssentials Complete-TR is a combination of two tablets, each with a distinct time-release profile and nutrient composition. Both tablets are added together at the onset of inoculation. One tablet contains a higher percentage of organically derived nitrogen, along with inorganic nitrogen, vitamins, minerals and yeast survival factors, and has a faster dissolution rate. This tablet provides the nutrients required to build biomass during the exponential phase. The other tablet is formulated As a winemaker who builds big wines, I need my fermentations to be able to stand up to the rigorous conditions of high sugars and elevated alcohol levels. Nutrition is key. So, I rely on Gusmer s MicroEssentials to give my fermentations the right nutrition to get me there. I have grown to trust the development team at Gusmer and believe in the way that MicroEssentials is produced. The proof is in the incredible success rate completing fermentation, in a difficult medium, even in the most problematic vintages. Jeff Farthing M.

Bioseutica Lysozyme Using Lysozyme to Combat Wine Spoilage Lysozyme is used by winemakers to control the growth of gram-positive spoilage bacteria, to control certain aspects of malolactic fermentations, and to stabilize wines after alcoholic fermentation or when malolactic fermentation is completed. Lysozyme plays an important role in establishing a healthy environment for alcoholic fermentation. Rather than use high levels of SO 2 to control the growth of Pediococcus, Lactobacilli, and other spoilage organisms, lysozyme may be used. Unlike SO 2, lysozyme does not inhibit yeast. It is recommended to add lysozyme to the grape must as early as possible at low levels between 100 and 150 ppm (10-15 g/hl). This allows early inhibition of some of the organisms that cause stuck and/or sluggish fermentations that can increase production of volatile acids. These low levels of lysozyme will also control the development of indigenous bacteria, thus preventing premature malolactic fermentations and allowing the alcoholic fermentation to progress smoothly. When using lysozyme to treat a sluggish fermentation, add it to the must at a level of 250 to 350 ppm (25 to 35 g/hl). If a wine begins to develop volatile acidity as a result of lactic acid bacteria activity, an immediate lysozyme dosage of up to 250 ppm (25 g/hl) will assist in reducing the bacterial count and help bring the volatile acidity production under control. Lysozyme will not inhibit acetic acid bacteria. Bioseutica Lysozyme Dose 100-500 ppm = 0.1-0.5 g/l = 0.4-2 g/gal Pack Sizes: 500 g and 5 kg Lysozyme Helps Control Histamine Production in Wine In general, biogenic amines (histamines) do not pose a major health risk for consumers; however, in some individuals histamine can trigger harmful or severe effects, known as false food allergies. Histamine can be produced by some types of bacteria in fermented food, and ethanol in wine may inhibit the metabolism of histamine, allowing further increase of histamine levels in the body. Recently, some large wine retailers have set a limit of 10 ppm histamine in the wines they will sell. In studies, the formation of histamine and other biogenic amines was mainly due to some strains of Pediococcus damnosus. Some strains of Lactobacillus and Oenococcus can also produce histamine. Lysozyme is effective in controlling the growth of bacteria which are responsible for histamine production.

Manufactured by BASF, Divergan F is used throughout the world for fining must and wine. BASF s unique polymerization process produces the purist polyvinylpolypyrrolidone, which is completely insoluble in must and wine. Divergan F is selective in binding phenolic species such as catechins and leucoanthocyanidins with minimal effect on flavor and aroma. It is frequently used to stabilize the delicate color in White Zinfandel and to help prevent pinking in certain white wines, thus ensuring a proper shelf life. Main Uses for Divergan F Correct and stabilize color in wine, particularly white and blush wines Help prevent browning and pinking (see below) Micrograph of Divergan F (PVPP) Freshen slightly oxidized wines Reduce astringency and bitterness in red and white wines Unmask fruity character Improve mouthfeel and finish of wine Treat press juice prior to fermentation to reduce astringency and bitterness Divergan F can be added directly to must or wine in a powder form or as a 5% w/w slurry in water (1 pound of Divergan F per two gallons of water). Typical dose rates are 0.5 to 4 pounds per 1,000 gallons with a contact time of 20 to 60 minutes and sufficient mixing. Divergan F is available in 20 kg and 5 kg packages. Prevention and Treatment of Pinking in White Wines with Divergan F White Vitis vinifera varietal wines can be prone to a phenomenon referred to as pinking. Pinking is the conversion of white wine to a pink color through slight oxidation of polyphenols. This reaction typically occurs in wines that are protected from contact with air and then suddenly exposed to air. Pinking generally takes place in white wines just after fermentation or bottling, although musts are not excluded. It is speculated that pinking and browning may occur simultaneously with pink compounds above visual threshold, acting to mask brown compounds that are just below visual threshold. Pinked wines usually retain positive flavors and aromas and are not influenced by ph changes or sulfur dioxide additions; however, warm storage temperatures and exposure to light increase the pinking rate. If the oxidation process continues, the pinked wines begin to brown, leading to undesirable sensory characteristics. Treatment of must (prior to yeast addition) with Divergan F - PVPP is an efficient preventative action. Divergan F at low dosages offers a cost effective means of treatment for high quality wines susceptible to pinking. 22 2017-2018 Gusmer Enterprises, Inc. Wine Products Catalog

Application Notes for Gusmer Oak Products Whether you are relying on oak to add complexity, reduce vegetative character, set color, or increase mouthfeel and suppleness - there is a convenient application method that will allow for reproducible and precise additions. Common Application Methods: 1. Crusher (granular) dose directly to red grapes at a reduced rate at the crusher to help with color stabilization and reduce vegetative character, but not impart recognizable oak character. Typical dose rates are 2-4 lbs / ton of fruit. 2. Fermentation (granular/chip/infusion bag) dose directly to juice and ferment in the presence of oak. This allows the oak character to become well integrated in the wine similar to fermenting in a barrel. The oak settles out with the lees. Typical dose rates are 15-30 lbs / 1,000 gal. 3. Wine (granular/chip/infusion bag) dose directly to barrels or tanks in a loose form or in an infusion bag during aging, micro-oxygenation, or pre-bottling processing steps. Typical dose rates are 5-30 lbs / 1,000 gal. 4. Concentrated Blending Wine (granular) dose at a very high rate directly to a portion of wine in a tank or tank press and blend back to finished wines. This allows for precise blending. Typical dose rates are 50-300 lbs / 1,000 gal. 5. Concentrated Blending Wine During Fermentation (granular) dose at a very high rate directly to juice in a tank and ferment in the presence of oak. This creates a blending wine with well-integrated character that can be used to blend back to finished wines. Typical dose rates are 50-300 lbs / 1,000 gal. Common Evaluation Methods: The true sensory characteristics of oak are revealed through extraction in wine; therefore, attributes may not be fully perceived in the dry oak. The oak extraction process allows soluble flavor and aroma compounds in the oak to be completely expressed, offering a better means to evaluate sensory characteristics and make decisions in regard to the optimal oak product and dose rate for the wine. Simple laboratory blending wines can be made by soaking a small sample of the oak in the subject wine at the desired corresponding weight/volume dose rate over a period of days. A more detailed method is offered below. Oak Granular Extract Protocol for Laboratory Blending Wines 1. Using a graduated cylinder, measure 1 liter of wine intended for oak treatment. a. Add 100 ppm of total SO 2 if the oak extract will be stored for long periods. 2. Add 36 g of oak per liter of wine. This is equivalent to 300 lbs / 1,000 gal or 3.6 kg / hl. 3. Add wine and oak to container with minimal headspace and seal or cover with Parafilm or Press-n-Seal. Stir or agitate multiple times during the first 24 hours to ensure oak becomes thoroughly wetted by wine. a. Stir daily, allowing the wine to extract oak compounds for 5-7 days at cellar temperature. 4. Remove oak particles from blending wine by passing wine through filter paper. Collect blending wine in small bottles to minimize oxidation. Sealed bottles can typically be stored in the refrigerator up to 8 weeks. 5. Based on the table below, set up seven 50 ml samples of wine to be evaluated including a control sample. 6. Conduct sensory evaluation of the samples to determine optimal dosage. Further variations may be desirable to achieve optimum results.

Application Notes for Sheet Filter Presses Operation Typically, a filter press consists of a series of plates equipped with inlet and outlet ports. Depending on the type of press, the ports may be internally or externally ported. When the press is closed and tightened through manual or hydraulic means, the plates, gasketed ports, and sheets are closed to form a tight seal for feed and filtrate passage. The unfiltered product passes through the inlet ports of the plate to the depth filter sheet. The depth filter sheet separates the undesired contaminant and allows the cleaned product to flow to the outlet plate. The outlet plate distributes the cleaned product to the discharge or outlet port. Advantages of Filter Presses Very versatile - full range of wine filtration applications Large filter area and additional surface area available with more plates Flexible, modular design with ability to conduct twostage filtrations Good process scalability from bench to production scale Consistent and reliable filtration results Low maintenance costs Outlet Port Stationary stainless steel plate Inlet Port Filter Press Flow Diagram (top view) Head plate Filter Sheets Outlet Plates Inlet Plates Filter Sheets Head plate Troubleshooting As with other separation and filtration equipment, regular cleaning, maintenance, and inspections should be conducted on filter presses.

Gusmer is proud to offer a full range of MilliporeSigma products, including those for filtration and microbial monitoring at bottling and throughout the winery. The Key to Reducing the Total Cost of Filtration: An efficient winery must operate on a Total Cost of Filtration basis. This method of operating recognizes that superior filter performance will yield better process economics over time. A Total Cost of Filtration approach also recognizes that factors influenced by filter performance are often more costly than the filters themselves. These factors include: Filter cartridge cost Wine lost or damaged Bottling line downtime and labor Cleaning and sterilization water and chemicals Quality assurance personnel and materials Product holds Product spoilage and recalls A high quality filter cartridge is key to maximizing total throughput and reducing the total cost of filtration. What final membrane is best for your winery? The membrane is the most important component of a cartridge filter. There are a variety of different membrane options available to the wine market with polyvinyldene fluoride (PVDF) and polyether sulfone (PES) being the most common. MilliporeSigma s PVDF cartridge filters provide many critical advantages over those with PES membranes.

Ozonated water generated on site, as required, eliminates the need to store, handle and dispose of harsh sanitizing chemicals. Ozone (O 3 ) is a naturally occurring, broad spectrum oxidizing agent that readily disintegrates organic material. When dissolved in water, it is an ideal sanitizing agent for food and beverage applications since it has the ability to disrupt cell wall membranes in microorganisms such as bacteria, yeast, mold, fungus, spores, viruses and biofilms faster than hot water, steam or chlorine. Produced when three oxygen atoms form a short-lived and unstable molecule (O 3 ), ozone will naturally revert back to atmospheric oxygen (O 2 ) after a brief period of time. Apply ozone enriched water (1-3 ppm ozone dissolved in ambient temperature water) as a sanitizer to the inside and outside surfaces of tanks, barrels and kegs, or on picking bins, sorting tables, conveyors, crushers, walls, floors and drains. Wet equipment surfaces with a low pressure spray of ozonated water and allow the surface to remain wet for a few minutes or more. Ozonated water leaves no harmful residue on contact surfaces, and requires no rinsing thus reduces water use. The PC series of ozone generators deliver a reliable and consistent supply of ozonated water at the workable flow rate range required to support good sanitation practices. An output of 1-3 ppm ozonated water, at a flow rate of 10 30 gpm*, gives the concentration/time (CT value) required for good log reduction of cells in mixed microbial populations.

Feed Gas Preparation concentrates atmospheric oxygen for efficient conversion to ozone Ozone Generation high energy fields in patented Floating Plate Technology TM reactor cells convert oxygen to ozone gas Mass Transfer ozone gas is dissolved into a stream of water; excess ozone gas is destructed Control/Monitoring maintains correct ozone concentration for application The standard PC16 and PC25 deliver a stable output of ozonated water that is easily controlled by the operator. With the available proportional control option, the PC16 and PC25 have the ability to adjust the output of ozonated water, while proportionately maintaining the desired concentration of ozone. *With typical water quality conditions PPM (Parts Per Million) PC25 Dissolved Ozone Output 5 PSI Inlet Pressure 15 PSI Inlet Pressure 25 PSI Inlet Pressure 5 PSI Inlet Pressure 15 PSI Inlet Pressure 25 PSI Inlet Pressure 10 10 Optimal 9 9 Optimal 1 Flowrate Flowrate Range 2 8 Range 8 3 4 7 7 5 6 6 6 7 8 5 5 9 4 4 10 11 3 3 12 13 2 1 2 1 14 15 16 17 0 0 18 19 0 5 10 15 20 25 30 35 0 5 10 15 20 25 30 35 GPM (Gallons Per Minute) Note: Municipal water supply, ambient temperature 60 o F and water temperature 60 o F for both trials.

How does it work? The OenoFoss wine analyzer uses Fourier Transform Infrared (FTIR) technology, a proven technology widely used for years to determine wine chemistry. Once the Start button is pressed, the OenoFoss executes numerous steps to deliver precise results in two minutes. First, the sample is scanned by mid-infrared light at two different path lengths using a Michelson interferometer. Wine components, such as ethanol and organic acids, absorb portions of the light during the scan. The scans are received by a detector and converted into digital interferograms. After the interferograms are collected, an algorithm based on Fourier mathematics transforms the interferogram frequency data into single beam spectra. By generating spectra at two different path lengths, potential sources of interference, such as scratches in the cuvette windows or internal moisture are compensated for, and a single corrected spectrum is generated. Patented calibration models developed and validated by FOSS using partial least squares (PLS) regression algorithms are used to transform the spectrum into wine chemistry values. These values are displayed on the computer screen. This ingenious device saves time and produces reliable and consistent results every time I use it. The OenoFoss saves money too considering how long it took before to run tests manually with other lab equipment. During harvest, juice samples could be run quickly allowing the winemaker to make decisions in an efficient manner. I love the OenoFoss and am so glad Renwood Winery made the decision to invest in this great tool!

Unequaled Technology The WineScan measures multiple parameters of wine and must using Fourier Transform Infrared (FTIR) technology to scan a liquid sample. This same FTIR technique is used to measure SO 2 levels by simultaneously scanning both the liquid wine sample and SO 2 in the gas evaporated from it. This new and unique gas detection technology provides both free and total SO 2 results in just over one minute. The information gained from both the liquid and gas phases provides the basis for an accurate measurement. During times when you only need the traditional liquid parameter results you can switch off the SO 2 gas phase measurement and get your results in only 30 seconds. Results for free and total SO 2 are delivered to a computer screen alongside the many other quality parameters provided by the WineScan. This provides a convenient onscreen comparison against other parameters of potential interest - such as ph and ethanol - in combination with SO 2. The instrument software makes it easy to look into different aspects of data with a range of user definable views. The WineScan is a complete wine analysis solution, providing rapid routine analysis of all critical wine parameters in one package that allows you to: Determine sugar levels for deciding when to pick for harvest Achieve the right balance between sugars and acids Measure yeast assimilable nitrogen (YAN) for avoiding stuck fermentation Measure volatile acidity Obtain a full picture of your wine with powerful combinations of parameters available simultaneously Ready-made calibrations for wine, must under fermentation, and must cover most quality parameters of all major types of wine.

Please call 707.224.7903 to discuss your needs, and for further information. Sulfide Detection Many wines are flawed with the off-aromas of sulfides. These compounds range from hydrogen sulfide and mercaptans to the higher molecular weight disulfides. The lower weight compounds tend to be treatable with copper alone, while the higher weight compounds first require treatment with ascorbic acid. Our Sulfide Detection and Treatment Panel uses varying levels of ascorbic acid and copper sulfate, followed by sensory trials to determine the nature and treatment of sulfide problems. See the following pages for prices. Gusmer s analytical services have been with us since the beginning of Six Hands Winery. We have always depended upon them for up to date technical advice on new and existing products and extensive analytic wine testing. We rely on Gusmer to help us make the best decisions possible for our products and ultimately our customers reap those benefits. Peter Marks, Winemaker Six Hands Winery - Walnut Grove, CA Membrane Filterability Will my wine prematurely clog my sterile membrane? The Membrane Filterability test will provide a clogging index - a numerical value that will tell you if the wine is ready to be sterile filtered or if further depth filtration is needed. The test requires 500 ml of wine and should be done not more than 5 days prior to sterile filtration/bottling. Membrane filterability test $40.00 Juice Panels and Organic Acids We offer two harvest juice panels - our regular juice panel and an extended juice panel that contains an organic acid profile (analyses shown on following pages). The organic acid profile will quantify tartaric, malic, lactic, acetic, succinic, and citric acid. The organic acid profile can be done on any sample. See the following pages for prices.

It is important to know the Total SO 2 and the Free SO 2 of the wine being adjusted. Total SO 2 includes both Free SO 2 and Bound SO 2. Bound SO 2 is SO 2 that is bound to other compounds in wine, like acetaldehyde, and does not provide significant antimicrobial or antioxidant protection. Free SO 2 consists of three species: molecular SO 2, bisulfite (HSO - 2-3 ), and sulfite (SO 3 ). Of these three species, molecular SO 2 possess the antimicrobial and antioxidant properties. The concentration of these species is ph dependent (refer to graph below), which is why ph should always be taken into account when calculating SO 2. At low ph levels, molecular SO 2 is the dominant form. Bisulfite is the dominant form at the ph levels of most wines (3.0 4.0). Sulfite exists as the dominant species at higher ph s (>7.0).

Wine Products Catalog Molecular SO 2 is responsible for the antimicrobial effect in wines and produces an indirect antioxidant effect by inhibiting oxidase enzymes. Literature suggests a molecular SO 2 level of 0.8 ppm for white wines at bottling, and a molecular SO 2 level of 0.5 ppm for red wines at bottling. These are general guidelines and each wine is unique, and other considerations should be taken into account before making SO 2 decisions and additions. Wines with a higher ph may need to have the ph corrected before making SO 2 additions. The chart below shows the distribution of Free SO 2 species at various phs and the level of Free SO 2 required to achieve the target molecular SO 2 level.
