The Northern Grapes Project was funded in 2011 by the USDA NIFA Specialty Crops Research Initiative.  The emergence of cold hardy, Vitis riparia-based wine grape cultivars in the 1990s created a new and rapidly expanding industry of small vineyard and winery enterprises in more than 12 states in New England, northern New York, and the Upper Midwest, boosting rural economies in those regions.  Read more.

Tales from the NE1020 Coordinated Variety Trials

Tim Martinson, Cornell University

Tuesday, February 14th, 2017

12:00 Noon Eastern (11:00 am Central)

7:00 pm Eastern (6:00 pm Central)

With Tim Martinson, and NGP team members with variety trials in their state.

Confirmed participants (as of February 7th):  Harlene Hatterman-Valenti (ND), Diana Cochran (IA), Terence Bradshaw (VT), Sonia Schloemann (MA), Anne Fennell (SD)

Since 2012, yield, fruit composition, and vine performance has been evaluated at experimental vineyards in ND, SD, NE, IA (2), MI (2), NY(2), VT, CT, and MA, as part of the “NE1020 Coordinated Variety Trial” multistate project.  We chose to focus on Frontenac, with four to five years of field data at each site providing a window on how the climate and site characteristics influenced vine performance.  Several challenges – including the 2014 polar vortex, and late spring frost (2015) – occurred at different locations, which illustrates some of the risks growers face.  In the first half hour, Tim Martinson will summarize overall data trends.  Then we will open it up to other project team members for informal questions and descriptions about trial results at their sites.
