Estate & Grower Vineyards

The Old Mission Peninsula AVA is an American Viticultural Area, established by Chateau Grand Traverse and located in Grand Traverse County, Michigan. The area is now known for well-regarded Michigan wine. The Old Mission Peninsula extends northward from Traverse City into the Grand Traverse Bay of Lake Michigan, ending at Old Mission Point. The peninsula is 19 miles (31 km) long by 3 miles (5 km) wide at its widest point. The climate on the peninsula is moderated by the surrounding waters (500 feet deep), helping to prevent frost during the growing season.
