The Old Mission Peninsula extends northward from Traverse City into the crystal clear waters of the Grand Traverse Bay of Lake Michigan, ending at the lighthouse at Old Mission Point. The Peninsula is 19 miles long and 3 miles wide at its widest point.

Recognized as an American Viticultural Area, Old Mission Peninsula AVA is known for its well regarded Michigan wine. The climate of the peninsula is moderated by the surrounding deep waters of the Grand Traverse Bay, with the West Bay reaching depths of over 400 feet and the East Bay reaching depths of over 600 feet. This deep water helps to prevent frost during the growing season, and keeps the air temperatures milder during the winter months.

The tip of Old Mission Peninsula is also located on the 45th parallel which is exactly half way between the equator and the north pole. Internationally recognized wine regions such as Bordeaux, France; Piedmont, Italy and the Willamette Valley in Oregon are all located along this same parallel. Cool climate varietals thrive in this region, such as Riesling, Chardonnay, Gewürztraminer, Pinot Gris, Pinot Noir, Cabernet Franc and Merlot.
