Bias Vineyard, near the small city of Berger, is located within the Hermann American Viticultural Area (AVA), designated in 1983. Röbller Vineyard and Winery near New Haven is also in the Hermann AVA. Wineries along both sides of the Missouri River are part of the Missouri Rhineland, whose vineyards were started by German immigrants in the mid-19th century. Before Prohibition, Missouri was the second-largest wine-producing state in the nation. Everything was closed down except for limited production of wine allowed for religious purposes. The state's wine industry had to be completely rebuilt, which has been taking place since the 1960s.
