Obsidian Wine Co. is the Molnar family's wine house, built on two estate vineyards: Poseidon Vineyard in the cool, windswept Carneros region and Obsidian Ridge, planted at 2,640 feet among volcanic obsidian rock in the Red Hills of Lake County. The portfolio pairs Carneros Chardonnay and Pinot Noir with intense mountain-grown Cabernet Sauvignon.
