Michigan's wine industry dates from after the repeal of Prohibition. With large plantings of Concord in the southwest, mostly for the Welch Grape Juice Company, the state was well positioned to enter wine production. Four large wineries (out of eleven wineries established by 1946) came to produce almost all Michigan wine: La Salle Wine and Champagne Company which was established in Windsor, Ontario, and moved to Farmington, Michigan; the Bronte Champagne and Wines Company of Hartford; Michigan Wineries (now Tabor Hill Winery) of Buchanan; and St. Julian Winery, which was also established in Windsor, Ontario, on the Canadian shore across from Detroit during Prohibition and moved to Paw Paw, Michigan, after repeal.
