Join winegrape growers from northwest Michigan at the 2021 Northwest Michigan Grape Preharvest Meeting on Friday, Sept.17 from 2-4 p.m. hosted by the Michigan State University Extension Grape Team.

This in-person meeting will be held at the research vineyard at the Michigan State University (MSU) Northwest Michigan Horticultural Research Center (6686 S Center Highway, Traverse City, MI).

In northwest Michigan, most winegrape varieties are in the middle of or have completed veraison. Harvest begins soon on early winegrape varieties being picked for sparkling wine.
