The Wisconsin Ledge AVA is an American Viticultural Area in northeast Wisconsin along the Niagara Escarpment (locally referred to as "The Ledge") in Door, Kewaunee, Manitowoc, Sheboygan, Ozaukee, Washington, Dodge, Fond du Lac, Calumet, Outagamie, and Brown counties.[3] Certified by the United States Department of the Treasury's Alcohol and Tobacco Tax and Trade Bureau on March 22, 2012, it covers an area of 3,800 sq mi (9,800 km2) and is the second AVA designation wholly in Wisconsin, following the Lake Wisconsin AVA established in 1994. The state's third is the gargantuan Upper Mississippi River Valley AVA which also covers land in Minnesota, Iowa and Illinois.[4]
The topography of Wisconsin Ledge is the result of ancient glacial movement over the region. The land on the peninsula slopes gently upward from the shores of Lake Michigan to the top of the Ledge, before dropping sharply off into Green Bay. Most of the vineyards lie on these eastern-facing slopes that benefit from constant air movement from Lake Michigan, which stores warmth during the summer. The presence of the lake produces a vacuum of sorts during the growing season: warm air over the lake rises, sucking colder air off the land and creating offshore breezes. Cold air cannot settle over the vineyards and there is a constant flow of warmer air, making the growing season here longer than in other parts of Wisconsin. Wisconsin Ledge's glacial soils are made up of gravel, sand and clay over limestone bedrock. An aquifer below the AVA provides mineral-rich ground water to the vines, encouraging deep root growth.[5][6]
