98% Cabernet Sauvignon, 2% Petit Verdot. 84% Sonoma County and 16% Napa. The Rock Arch vineyard block, the primary source for this wine, is still going strong after 38 years, pruned to vertical cordons that create an ideal dappled-light environment for the clusters to ripen in.

A purple core with a cherry purple rim, on the palate dense and concentrated with grippy, tooth-staining tannin and full body, crème de cassis and dark chocolate, mint and rosemary herbal notes, dusty soil and Oolong tea.
