Obsidian Ridge Vineyard is planted at 2,640' atop the Mayacamas range north of the Napa Valley. This is one of the newest American Viticultural Areas, named Red Hills Lake County for the distinctive volcanic soils that define this remarkable mountain appellation. The vineyard′s red soils are shot through with obsidian rock—this steep, sloping terroir of obsidian gravel is all that a winemaker could hope for. The unrestricted drainage and meager soil fertility produce wines with great tannic structure.

Your nose is teased with coffee nibs, blueberries and black pepper, but a shy side emerges after time in the glass: blackberries and a gentle floral lift. Flavors of dark chocolate, coffee and fresh blackberry are carried on silky tannins—they speak clearly, but don’t shout. 2017 is a riper, fuller, but quieter vintage of our signature bottling of Cabernet Sauvignon.
