Wisconsin Ledge AVA
Wisconsin Ledge is an American Viticultural Area (AVA) located in northeast Wisconsin along the western end of the Niagara Escarpment (locally referred to as "The Ledge") within Door, Kewaunee, Manitowoc, Sheboygan, Ozaukee, Washington, Dodge, Fond du Lac, Calumet, Outagamie, and Brown counties. It was established as the nation's 203rd and the state's third appellation on March 22, 2012 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by Steven J. DeBaker of Trout Springs Winery in Greenleaf, Wisconsin, on behalf of himself and local vintners, proposing the viticultural area named "Wisconsin Ledge." The AVA lies on the Door Peninsula, a 138-mile-long (222 km) by 55-mile-wide (89 km) landform, encompassing 2.4 million acres (3,800 sq mi) within the state borders.
