Status of the Native Iowa Wine Industry - Latest Report

Craig Tordsen with our ISU Value Added Agriculture Program has just completed a financial report showing the current status of the Native Iowa Wine industry as of the state of Iowa’s fiscal year ending 6-30-13. The following table shows our wine sales and production over the last three years.
IA Native Wine Production & Sales June 2013
Iowa native wine sales as a percentage of total wine sales has been in the 5-6% range for the last 4 years with total sales running from 225,000 to 267, 000 gallons. The number of licensed wineries has been in the 90-100 range over this same period. Our industry has matured with new wineries starting as others close down. We now have approximately 310 commercial vineyards down from a high of around 425 several years ago. Our commercial acreage seems to be steady at round 1,200+ acres. Consumer demand for U.S. wine continues to grow each year. So what seems to be slowing our Iowa native wine industry?
I understand that each additional 1% of market share is increasingly difficult to obtain but,….do we need a stronger statewide marketing effort? Do we need to improve our wine quality? Are our prices too high? These and other questions need to be investigated by our Iowa Wine Growers Association in the near future. We need some new and better methods to gain greater market share for Native Wine in Iowa. mlw

Performance of recently released New York grape cultivars in Iowa trials

(Dr. Paul Domoto, Professor of Horticulture & Extension fruit specialist )
Aromella grape clusters‘Aromella’ was named and released in 2013 by Cornell University and the New York State Agricultural Experiment Station, Geneva, NY. It is a cross between ‘Traminette’ and ‘Ravat 34’, and was evaluated in Iowa as NY76.0844.24 in the 2003 Wine Grape Cultivar Trial http://viticulture.hort.iastate.edu/research/research.html#trial . Vines of NY76.0844.24 were planted at the Armstrong Research Farm, Lewis (ARF), Horticulture Research Station, Ames (HRS), Northeast Research Farm, Nashua (NERF), and Southeast Research Farm, Crawfordsville (SERF) in 2004. Vines at the trial sites were exposed to several freezing events that affected performance and primary bud survival (Table 1). Based on primary bud survival, NY76.0844.24 would be classified as a "hardy" selection. As reflected by the annual pruning weights and length of established cordon (Table 2), the vines were difficult to establish in the ISU trials and never attained the pruning weights reported in New York (4.1 lb/vine). This can be attributed to late lignification (periderm formation) of the shoots on more vigorous growing sites such as HRS, ARF and SERF, and an extreme sensitivity to drift from 2,4-D and similar growth regulator herbicides (Table 3).
Under Iowa growing conditions, bud break on NY76.0844.24 occurred with Frontenac and Frontenac gris. Compared to the production reported for New York (average production of 25.4 lbs/vine with clusters averaging 0.27 lbs), it was not productive at the ISU test sites and cluster weights were variable (Table 4). This was attributed to exposure low winter temperatures, spring frosts, poor fruit set from exposure to growth regulator herbicide drift or rain during the bloom period, and berries being prone to shelling (dropping) as they approached maturity. Harvest dates and fruit quality indices varied between sites (Table 5) and growing season (Tables 6).

Lisa Smiley Elected 2014 Chair of ASEV - ES

Lisa Smiley of Cannon Falls Minnesota was recently elected Chair of a national organization, the American Society for Enology and Viticulture Eastern Section (ASEV-ES).
The American Society for Enology and Viticulture, founded in 1950, is a non-profit, scientific organization dedicated to promoting the interests of enologists, viticulturists, and others in the fields of wine and grape research and production throughout the world. It's membership of 2,400 includes professionals from wineries, vineyards, academic institutions and organizations. In addition, it has 120 Industrial Affiliates.
The society publishes the American Journal of Enology and Viticulture and is headquartered in Davis, California. ASEV-ES consists of all US states east of the Rockies and includes the Canadian Provinces of Ontario and Quebec.
Véraison is a viticulture (grape-growing) term meaning "the onset of ripening". It is originally French, but has been adopted into English use. The official definition of veraison is "change of color of the grape berries." Veraison represents the transition from berry growth to berry ripening, and many changes in berry development occur at veraison.

8-(8 or 13), Harvest Time Sensory Workshop – Perryville, MO

What: MU Grape & Wine Institute
These workshops will consist of a short presentation about grape physiology with an emphasis on the changes that occur during ripening and an introduction to principles of sampling grapes within the vineyard after veraison. There will several "hands-on" experiences during which you will sample and evaluate all aspects of the ripening grape…pulp, skins, and seeds. We encourage you to bring grape samples from your vineyard, ideally picked the same morning, for evaluation.

Show n Tell

I was invited Irv Geary to meet with several other members of the Minnesota Grape Growers Association on 7-23-13 at the University of Minnesota's Horticulture Center at Excelsior, MN. Irv has a winery at Taylor, MN called Wild Mountain Winery. We met for a day-long session to outline Best Management Practices to consider for Minnesota Vineyards. Our meeting ended with a tour of the UMN Horticulture Research Center vineyards. The UMN HRC is located at Excelsior, MN.

(Above-R) Ventura grape. Peter Hemstad, the UMN HRC grape breeder felt that this grape would grow well in Iowa. It is a highly productive white wine grape that produces a somewhat acidic white wine with labrusca flavors . 7-23-13
Lenticel: Small, round or elliptical, pore-like structures, resembling freckles, on the bark of some woody plants that allow gas exchange between the atmosphere and the interior tissues. In most Vitis species of grapes, lenticels are absent on shoots but present on berries and pedicels.
The next day after being at the UMN HRC I stopped by to visit with Del Schott who owns and operates Bevens Creek Vineyard & Nursery that is located about 15 miles southwest of the Minneapolis metro area. Del is one of two grapevine nurseries in the U.S. that sell Petite Pearl grape plants. He also sells the Quebec selection of Frontenac Blanc grapes.
This 6 acre vineyard was established in 2002. Del also has a small research winery where he tests the wine quality of the new grapes he is growing. Del works very close with grape breeder Tom Plocher in planting and testing new trial cultivars. Bevens Creek Vineyard & Nursery is very well managed. It is an excellent site for a vineyard and nursery. I want to thank Del for showing me his operation. You can learn more about his Petite Pearl grape here: http://www.petitepearlgrape.com/

(Above-L) Del uses unique Geneva Double Curtain- GDC tubular metal trellis arms. The northarm is about 1ft. taller than the south arm and the wires lie in a U-shaped hook allowing the wires to be lowered at harvest. 7-24-13
(Above-R) Del cuts up pieces of permeable soil erosion control fabric for weed control around new vines. This fabric will last several years and can be re-used if needed. A 3’ wide roll will cost around 10 cents per running foot. 7-24-13

My next stop was St. Croix Vineyards in Stillwater, MN. Peter Hemstad, co-owner of the winery had his son Noah meet me and show me around the vineyard and winery. I really enjoyed the tour and the wines. Matt Scott, the General Manager and Ken who was behind the tasting room bar treated me very well. This is a winery that I highly recommend people visit. The wines were fantastic!

Cannon River Winery
My next stop was Cannon River Winery at Cannon Falls, MN. After checking out their spacious downtown winery and buying some wine I headed toward their 20 acre vineyard located about 5 miles south of Cannon Falls. The vineyard is located on top of a tall hill. Jarred McCarthy, the vineyard manager was there tending the vines when I arrived. I want to thank Jarred for giving me a tour of the vineyard.
