Michigan winemakers face new threats from wildfire smoke

Winemakers in Michigan are facing new climate-related concerns as wildfire smoke begins to impact the region. In July, smoke from wildfires in Canada and Minnesota blanketed northern Michigan, creating significant haze and minimal visibility in areas such as the Leelanau Peninsula.

While current harvests appear unaffected because the smoke arrived early in the growing season, industry professionals are concerned about “smoke taint.” This phenomenon occurs when grapes are exposed to smoke for extended periods, resulting in unwanted flavors in finished wines, such as notes of burnt bacon or barbecued food.

The Michigan wine industry, valued at nearly $9 billion, may need to adopt new adaptation strategies similar to those used by wine regions in Australia and the U.S. West Coast. Winemakers are considering increased laboratory testing to detect smoke-associated compounds in grape samples to mitigate future risks.
