The state of the USA with the capital Madison borders on Lake Michigan in the east and on the Mississippi in the west. In 1841, the Hungarian Agoston Haraszthy (1812-1869), who had immigrated from Austria-Hungary, founded today's Sauk City. He was engaged in the cultivation of hops and grapes before he later went to California, where he gave decisive wine-growing impulses. Lake Wisconsin is the only AVA classified. The wine-growing center is the land around Green Bay, especially Door County. Well-known production companies are Cedar Creek Winery, Orchard Country Winery, Orchard Country Winery and Woodland Trail Winery. From Wisconsin comes the important vine grower Elmer Swenson (1913-2004).
