Old Mission Peninsula is an American Viticultural Area (AVA) located in Grand Traverse County on the Old Mission Peninsula landform extending into Grand Traverse Bay of Lake Michigan in Northern Michigan. The peninsula is approximately 19 miles (31 km) long and no more than three miles (4.8 km) wide at any point bracketed by Traverse City at the southern end and Old Mission Point on its northern end. The wine appellation was established as the nation's 92nd and Michigan's fourth AVA on June 8, 1987, by the Bureau of Alcohol, Tobacco and Firearms (ATF) after reviewing the petition submitted by Edward O'Keefe, President of the Chateau Grand Traverse Winery, proposing a viticultural area named "Old Mission Peninsula". The total size is approximately 30 square miles with 1,800 acres (730 ha) of vinifera vineyards for wine production in the Old Mission Peninsula.
