Adjacent to an ancient volcanic cinder cone and nestled into the remote eastern edge of High Valley, our Volcano Ridge vineyard features steep slopes and strikingly red volcanic soils. Originally planted in 2003 and 2004, the vineyard totals 85 acres and is planted to a sizable number of varietals, including Cabernet Sauvignon, Syrah, Malbec, Petite Sirah, Mourvèdre, Grenache and Zinfandel. The vineyard elevation ranges from 1900 ft. to 2200 ft. The volcanic sands and tephra (small, fused sand pebbles) of the Konocti series make for excellent drainage. Vines struggle in these soils, and the intensity of that struggle is reflected in the layers of complexity and structure, in the concentrated fruit, and in the final expression of Volcano Ridge wines.
