6 THE TECHNOLOGY Here is another classic example of a unique VA Filtration technology doing the job smarter. Our Lo-Cross-Flo mobile microfiltration system is not a cross flow filter system, but uses low cross flow filtration mode, where tangential wine flow is kept to a minimum. Instead, utilising the considerably increased surface area, to compensate for any loss in flow rate, we can feed semi dead-end, as well as have a lower flux rate per m² with an immediate lower trans-membrane pressure. And when needs be, the filtered solids within the membrane can be backwashed into a system storage tank where it can be further filtered using cross flow filtration. Ultimately this system, operating in Australia, South Africa and USA, creates a far gentler, one-step filtration for your wine. THE SPECIFICATIONS Flow rate: Power required: Final filtered quality: Membrane type: Maximum operating pressure: Average operating TMP: Maximum inlet turbidity of wine: Expected losses 2,000-4,000 Litres/hr (White) (530-1,000 gal/hr) 1,200-2,400 Litres/hr (Red) ( gal/hr) 208/240V (20 amp), 480V (20 amp) or 380V (30 amp) <1 NTU Hollow fibre polyethersulfone or spiral wound 20 psi 3-8 psi 600 NTU (White), 200 NTU (Red) 1-2% of overall volume THE ADVANTAGES One step, sterile filtration No heat increase in process means less oxidization Less handling of your wine Your wine passes through bottling line filter cartridges

8 UNTAINTED WINE FOR GOOD Since 2004, we have been providing winemakers around the world with a unique single-pass treatment process to remove the musty, moldy aroma of TCA (2,4,6, Trichloroanisole) and TBA (2,4,6, Tribomoanisole). The wine passes through a system of filter media canisters that targets TCA/TBA and all related anisoles. Once again, this is a gentle, oncethrough filtration, and wine quality is untouched. One barrel to large volumes can be processed. THE SPECIFICATIONS Volumes processed: Processing Rate: Detectable TCA/TBA levels in wine: TCA levels treatable successfully: Levels analysed exiting the system: Wine quality after TCA/TBA removal: Single barrel to 400,000+ Litres (100,000+ gallons), 4-4,000 Litres/hr (1-1,000 gal/hr) < 2 µg/litre (0.5 µg/gallon) Depending on wine type < 30 µg/litre (7.5 µg/gallon) < 1µg/Litre (.25 µg/gallon) Excellent POTENTIAL CAUSES OF TCA There s quite a few but be particularly aware of chlorinated process water, barrels, wooden pallets, corks, filter media, oak chips, packaging products and wooden structures. CORK TAINT PROBLEM! WHAT DO I DO? First, send a sample of your suspect wine in a foil capped, glass container to a reputable lab. Then, if the results aren t good, send us two 750ml sample bottles for a TCA removal test. We ll have a result back to you in 2 days.

9 LESS IS MORE Bottom line Lees can make you money. Our experience has shown that after picking, crushing and tanking, Lees still contains about 80% juice. With roughly 5% of your volume being Lees, that adds up. With your choice of a 10m² or a 4m² rotary drum vacuum filter, and treating from 400 litres up to 2,400 litres an hour from fully self-contained on a trailer, you will be increasing your profit. THE SPECIFICATIONS Flow rate: Power required - Uninterrupted: Final filtered quality: System type: Anticipated recovery: Cake disposal: On Site Requirements: Litres/hr (4m²) ( gal/ hr (4m²) 208/240V (30 amp) or 480V (20 amp) NTU Rotary Drum Vacuum Filter 60-80% on Red wine lees 70-80% on White wine lees Winery responsibility Continuous water supply Sufficient 3 phase power supply

11 Have you had a stuck ferment? Have you tried a re-start, but the fermentation has stuck again? Are you struggling to re-start a fermentation due to excessive VA or ethanol content in the wine, but would rather not pay for both VA reduction and ethanol reduction? Would you like to stop your fermentation at 14.7% ethanol, but there is still 10 g/l of residual sugar remaining? NOW YOU CAN WITH OUR LATEST RESIDUAL SUGAR RE- DUCTION PROCESSTHE TECHNOLOGY Wines with residual sugar levels of up to 20 g/l (2%) can be reduced to less than 4g/l using a revolutionary membrane filtration process. The process, developed though extensive in-field testing, is designed to target the glucose/ fructose only and remove these compounds from solution. During the reduction of residual sugar, several other processes are possible, these include VA reduction, DES reduction as well as other low molecular undesirables present in the wine at the time. The ethanol content of the wine remains constant throughout the treatment. If ethanol reduction is required though, this can be achieved through our on-site ethanol reduction system. Typical losses depend on the starting content of the residual sugar in the wine. A typical example follows: Starting volume: Starting glucose/fructose: Required glucose/fructose: Sugar to be removed: Starting TA: Volume of sugar solution: Volume of wine at end of run: Ending TA: 10,000 liters 10 g/l 2 g/l 80 kg 7 g/l 400 liters (at end of run) 9,600 liters containing 2 g/l of glucose/fructose 6.1 g/l As one can see there is a reduction in the TA as well as the volume associated with the process. The remaining sugar solution is at a 20% concentration, with a TA of close to 15 g/l and can be utilized as a concentrate for additions to other ferments. The process is gentle on the wine and has been designed as usual with the integrity of the wine in focus.
