In August of 2015, the TTB received a petition from the Straits Area Grape Growers Association proposing the establishment of the “Tip of the Mitt” AVA on Michigan’s Lower Peninsula. As announced on July 21, 2106, the new Tip of the Mitt AVA has been approved and will be effective as of August 22, 2016.
The 2,760 square mile AVA (American Viticultural Area) is bordered by Grand Traverse Bay, Little Traverse Bay, and Lake Michigan to the west; the Straits of Mackinac to the north; and Lake Huron to the east. The AVA includes the counties of Charlevoix, Emmet, Cheboygan, Presque Isle, Alpena, and Antrim Counties (or portions thereof). There are currently 41 commercial vineyards and 8 wineries in the area. There are now just 94 acres of commercial vineyards, although there are plans for an additional 48 acres to be planted in the next few years. The AVA is not contained within any existing AVAs.
According to the petition, the unique features of the AVA include its climate and soils. The surrounding lakes, straits, and bays provide a moderating effect on the climate, making the area slightly warmer, less prone to freezing temperatures, and with a slightly longer growing season than the areas to the south.
The soils in the area are comprised mainly of coarse-textured glacial till (a mixture of clay, sand, gravel, and boulders). The soils within the Tip of the Mitt AVA have much higher levels of organic matter and water-retention capacity than those to the south, so one challenge of wine growing in the area is to control moisture accumulation and the vigor of the vine canopy. A positive aspect of the soils within the AVA is that they heat slowly in the spring, which effectively delays bud break until the greatest risk of spring frost has passed
The term “Tip of the Mitt” refers to a common nickname used for the area, referring to the mitten-shaped landmass of Michigan’s Lower Peninsula. (For reference, the mid-eastern region is often identified as “The Thumb.”)
The Tip of the Mitt is the fifth AVA in Michigan. The others include the Lake Shore Michigan AVA, the Leelanau Peninsula AVA, the Old Mission Peninsula AVA, and the Fennville AVA.
