The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the approximately 2,760-square mile "Tip of the Mitt" viticultural area in all or portions of Charlevoix, Emmet, Cheboygan, Presque Isle, Alpena, and Antrim Counties in Michigan. The viticultural area is not located within, nor does it contain, any other established viticultural area. TTB designates viticultural areas to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase.
