Obsidian Ridge Vineyard is sits on a volcanic flow at the northern tip of the Mayacamas Range at a half mile of elevation. Vines planted in 1999 on red volcanic soils shot with black obsidian are subject to an unforgiving, mountain climate. Low humidity, cold night time temperatures, and ultraviolet exposure 10% greater than at sea level all contribute to developing small grapes with dark color, thick skins, and intense flavors. The Estate Cabernet Sauvignon captures the personality and verticality of this complex site. Multiple vineyard blocks are harvested in dozens of unique lots. Fermentation is completed in 8-10 days and wines are pressed immediately to avoid over extraction of the skins. Obsidian wines are the only Cabernet Sauvignons in California (perhaps the world) aged in 100% Hungarian oak barrels. Our source forest in Tokaj is planted to the same oak species used in France, Quercus Petraea, however the trees grow more slowly due to the volcanic soils, resulting in 30% higher density of the wood. Tasting notes: The Estate Cabernet is the signature wine of Obsidian Ridge and embodies the complexity and wildness of the site. The structure and intensity of upper blocks is complemented by aromatics and acidity of cooler blocks. Aromas of freshly-cut red cherries with hints of cinnamon and spice. Flavors of mulberry and plum, woven with dried oregano and chaparral, are supported by a rich texture of fine, leathery tannins. Notes of star anise, cinnamon, and orange peel inspire pairing with Mediterranean dishes. Fresh acidity keeps the wine lively on the finish. 2021 Blend: 90% Cabernet Sauvignon, 2% Petit Verdot, 3% Malbec, 2% Syrah, 3% Petite Sirah.
