Folie a Deux was founded in 1981 by two psychiatrists who, as a nod toward their profession and their interest in wine, named their winemaking enterprise the French term for “a passion shared by two.” The Oakville estate has vineyards in the Russian River Valley, Dry Creek Valley and Alexander Valley. Today the estate is owned by a group of private investors and makes Chardonnay, Merlot, Cabernet Sauvignon, Zinfandel and Pinot Noir.
