The state was founded in 1858 and is located in the Midwest of the USA in the north on the border with Canada. Because of its many lakes, Minnesota is also called the "Land of 10,000 Lakes". There are extremely cold winters with temperatures below minus 30 °Celsius. Therefore, the University of Minnesota has pushed forward research into cold weather viticulture and extremely frost hardy new varieties. These include Edelweiss, Frontenac, La Crosse, St. Croix and St. Pepin, which were created by the vine grower Elmer Swenson (1913-2004) on his farm near Osceola. The over 400 grape growers are united in the "Minnesota Grape Growers Association". The only AVA area is called Alexandria Lakes. Well known producers are Alexis Bailly Vineyards, Luedke's Winery, Minnesota Wild Winery, Morgan Creek Vineyards, Saint Croix Vineyards.
