Lake Michigan Shore AVA is an American Viticultural Area located in southwest Michigan.
Located in the state's traditional "fruit belt region", Lake Michigan Shore is the oldest modern commercial grape region of the state and home to a majority of Michigan vineyards and half of the state wine grape production.
The AVA boundaries include the smaller Fennville AVA and extend as far as 45 miles (72 km) inland from the lakeshore; however, the climate and glacial moraine soils are relatively similar throughout.
Lake Michigan Shore AVA has a warmer growing season, as much as two weeks longer than the Leelanau Peninsula AVA and Old Mission Peninsula AVA, both of which are in Northern Michigan.
