Wine-Grower-News #97 August 14, 2009 (Next Newsletter in One Week!) Midwest Grape & Wine Industry Institute: http://www.extension.iastate.edu/wine Information in this issue includes: From VINES to WINES A Book Review Wines of The World New Class at VESTA this Fall It s Grape Sampling Time Northwest Iowa Grape Growers Host Harvest Preparation Workshop New Iowa State Fair Vine/Wine Display has been a HUGE Success We now have 5 mechanical grape harvesters in Iowa Show n Tell Comments from Readers Quote of the Week Articles of Interest Neeto-Keeno WWW Stuff From VINES to WINES A Book Review From VINES to WINES The Complete Guide to Growing Grapes and Making Your own Wine by Jeff Cox, copyright 1999 is a book I have been slowly reading through over the last few months. I purchased this paperback book for $18.50 from Mary Jo of MDT & Associates at their vendor booth when they attended the Iowa Wine Growers Association s March, 2009 annual meeting in Des Moines. They always have an excellent display of vine/wine books as part of their vendor display. This 236 page book is oriented as a hobby winegrower/winemaker overall guide, but is thorough enough to be read by commercial winegrowers/winemakers. It covers all the bases a hobby winegrower/winemaker needs to consider to get started. It starts with picking the vineyard site and takes the reader through planting the vineyard, trellising, growing, pest control, winemaking, bottling, and cellaring. It has an excellent section on pruning. It covers both vinifera and American/French hybrids. Jeff Cox, the author lives in Sonoma where he 1

has a hobby vineyard and is a hobby winemaker. He has written over 17 books on food, wine and gardening. You can read more about him and his other books here: http://www.jeffcox.net/ I would definitely recommend this book to the hobby winegrower/winemaker or commercial winegrape grower. The winemaking portion is pretty basic, so I would NOT recommend it to a commercial winemaker to read. Wines of the World New Class at VESTA this Fall Viticulture Enology Science and Technology Alliance (VESTA)is pleased to introduce Wines of the World, VIN 274, to the course curriculum beginning in the Fall 2009 semester. The Fall class enrollment deadline is 8-29-09. This course, taught by VESTA instructor Ray Johnson, is intended for those individuals who wish to further their understanding of wine styles and builds on the knowledge developed in VIN 266, Sensory Evaluation. It is appropriate for commercial winemakers who wish to understand how the wines that they produce compare and contrast with the most popular and important wine styles around the globe. It will also be of benefit to the wine enthusiast who is interested in reaching advanced levels of appreciation and an understanding of global benchmarks. Students will practice sensory analysis at home to further their sensory evaluation skills and techniques. Please visit http://vesta-usa.org/ for complete details including the course syllabus, registration information, and class times. For further information contact Emily Gray, VESTA Graduate Assistant: Ph: 417-836-8967 or Emily323@MissouriState.edu Northwest Iowa Grape Growers Host Harvest Preparation Workshop When: 7 9 p.m. Tuesday, August 18, 2009 Where: ISU Extension Calhoun County office, 521 4 th St., Rockwell City, Iowa http://www.extension.iastate.edu/calhoun/ Who: Scott Schweers of Spotted Horse Vineyard and Winery, Arcadia, Iowa: http://www.spottedhorsevineyards.com/ Sponsored by: Northwest Iowa Grape Growers Association: http://nwiowagrapegrowers.com/ Cost: $12 each. Comments: Scott Schweers will lead a discussion of harvest parameters and concerns for harvesting your grape crop. He will explain what wineries are looking for in terms of grape sugar levels, PH levels, and acid levels in harvested grapes, and show you how to monitor ripening of your crop. As we do at every meeting, we will end the evening with a tasting of local Iowa wines. Two more workshops are planned for this year, a winemaking and winery issues discussion on September 22, and October 20, which we hope will be a winery tour. Walk-in's are always welcome, if you know that you will be attending this workshop, please Contact Norm Lewman so that they can have adequate materials on hand at: nwiaagrapegrowers@yahoo.com 2

It s Grape Sampling Time Grape harvest is here. Edelweiss grapes are are now being harvested in southern Iowa. Marquette and GR-7 will soon follow. Make sure you take a good berry sample when determining your harvest date. A correct sampling procedure per cultivar sampled should take into account: a. Sun exposed clusters b. Shaded clusters c. Berries from top, middle and tip of cluster (berries at tip of cluster ripen last) d. Berries from either side of row (Above) Crushed Frontenac berries in a e. Berries from different parts of the canopy Zip Lock bag with refractometer. f. Berries from primary, secondary or third clusters on cane (If you are not going to harvest the green clusters, don t sample them!) g. Avoid sampling from vines at end of row or from odd vines. h. Sample at the same time of day Page 145 of the Midwest Grape Production Guide suggests sampling a minimum of 100 berries from multiple clusters on at least 20 vines. http://ohioline.osu.edu/b919/index.html Page 576 of General Viticulture, Winkler, Cook, Kliewer and Lider recommends berry sampling over cluster sampling and suggests taking berry samples from 20 random sampled clusters. Sampling should start 2-3 weeks prior to harvest. Page 69 of Growing Grapes in Missouri, recommends collecting a random sample of 200 berries representing the entire crop. Sample different cultivars and areas separately. Start sampling 3 weeks prior to harvest every 3-4 days prior to harvest. Collect samples the same time of day. Crush the grapes and extract the juice to test. http://mtngrv.missouristate.edu/publications/ggimpub.htm Page 97 of From Vines to Wines by Jef f Cox recommends taking two separate 100 berry samples, testing separately and averaging the results. I would suggest using the following procedure for berry sampling: 1. Start sampling 3 weeks prior to harvest every 4-5 days, shortening your sample times the closer you get to harvest. 2. Sample the same time each day 3. Randomly select 20 vines. (no vines at end of the row) 4. Randomly select 1 berry each from the middle of 5 randomly selected clusters on each of the vines. 5. Place the 100 berry sample in a plastic ziplock bag and hand crush 6. Sample the juice poured from the bag. 3

Taking a good representative sample of clusters instead of berries is also a recommended practice by some winemakers. Paul Tabor of Tabor Home Vineyards & Winery at Baldwin, Iowa recommends this procedure to his growers. He feels that cluster or bunch samples are far closer to the actual parameters for Brix, ph and TA in the must than berry sampling. His experience has shown that berry sampling tends to show the vineyard to be riper than it actually is. The cluster sampling also shows the vineyard to be a little riper than it actually is from measurements taken from the must, but much closer than berry sampling. New Iowa State Fair Vine/Wine Display has been a HUGE Success There is new Iowa vineyard and winery display at the Iowa State Fair this year. Grandfather s Barn and surrounding grounds have been turned into a large walk through Wine Experience fairgoers can stroll through. Barb Rasko, publisher of MakeMineWine magazine is the barn superintendent. Over 35 volunteers have signed up to help staff this display (Thank You!). Kevin Smith (Turkey Time Concessions & Middle River Vineyard), Randall Vos (DMACC) and myself have also been helping with this display. FEEL FREE TO STOP BY AND VOLUNTEER A FEW HOURS IF YOU ARE VISITING THE STATE FAIR we have been VERY busy! This Wine Experience has been VERY successful so far. This has been the largest attendance at any Iowa vine/wine activity that I have ever been involved with. I thought it was amazing when people picked up over 2,250 Iowa Wine and Beer Promotion brochures during the 3 days of the Farm Progress Show held in Boone, Iowa last year. Fairgoers have picked up over 3,500 of these brochures in the first 2 days of the fair this year. Conversations with people visiting this display have been absolutely amazing. The comments and discussions have ALL been very positive. I can t tell you how many times Iowan s have come into the barn and expressed how excited they are about the growth of our industry. Many have great stories to share about wineries they have visited and the wines they have tasted. I think our Iowa vine/wine industry has now been officially accepted by Iowans. You can see the PRIDE in their eyes when they walk through the display and talk with their friends. These are some of the things people can see and do when visiting the Wine Experience: a. Taste Iowa wine. b. Buy bottles of 2009 State Fair labeled wine. c. Three rounds of Grape Stomping at 5:30 p.m. each day. d. Special topic speakers at 2 p.m. each day. e. View the winners of the amateur wine and beer competition. f. View the winners of the commercial wine competition. g. Watch videos about our industry. h. Watch how we test grapes for ph and Brix. i. View the many exhibits. The Iowa State Fair opened on Thursday, 8-13-09 and will run through Sunday, 8-23-09. They expect to have over 1 million people attend again this year. Feel free to stop by and spend some time talking about our industry as people come through. Grandfather s Barn is the large white barn on top of the hill on the east side of the Fairgrounds. The Des Moines Register listed the Wine Experience as the #5 pick to visit at the Iowa State Fair. I guarantee that you will enjoy this experience. 4
