What are the best parts of Minnesota for growing grapes?
Grapes can be grown as a hobby throughout the state, although only very early ripening and cold hardy types should be tried in northern Minnesota. In terms of commercial viticulture, the most promising areas in the state are along the Mississippi, Minnesota, and St. Croix river valleys in the southern third of the state. These valleys were created in glacial times and have large hills surrounding them as well as gravelly or sandy soils well suited for grapes.
