Mari Vineyards brings Old World ambition to Old Mission Peninsula. Founded by Marty Lagina — yes, the treasure hunter from History Channel's The Curse of Oak Island — the winery's vision was never small. A 37,000-square-foot underground cellar carved into the peninsula's glacial hills houses barrel rooms, a production facility, and a cave tasting gallery that feels transplanted from Tuscany.
The wines match the ambition. Winemaker Sean O'Keefe works with Italian varietals that most Michigan winemakers wouldn't dare attempt: Nebbiolo, Sangiovese, and Dolcetto alongside more expected regional stars like Cabernet Franc and Riesling. The maritime influence of Grand Traverse Bay on both sides of the narrow peninsula creates a microclimate that extends the growing season just enough to ripen these Mediterranean grapes.
The tasting room sits atop a hill with sweeping views of East Grand Traverse Bay and the surrounding vineyard blocks. It's easily one of the most striking winery settings in the state — and a must-visit for anyone exploring Old Mission.
