Here at Red Dog Vineyards and Grapevine Nursery we are currently growing many Elmer Swenson varieties and other cold hardy grape varieties from around the world to determine their usefulness as wine grapes in the Midwest. For many of these grapes we will be conducting wine trials as soon as we can produce enough fruit!
We are also researching the use of various root stocks to improve vine performance and match the rootstock to soil types. Currently we are working with SO4, 1103P, Teleki 5C, 101-14Mg, and 3309C rootstock.
We have been planting many winter hardy French hybrid and Eastern European grapes to see what will work in our 5a climate zone. Many of these vines could hold great winemaking potential.
We are also using these grape varieties in our private breeding program to develop new grape varieties!
