Every wine Theorem makes comes from one of two mountains — where elevation, volcanic soils, and ocean air shape everything we do. We grow the grapes ourselves and pick by taste in small passes, keep each lot on its own, and use a light hand in the cellar, so the vineyard leads. No purchased fruit. No blends. Just the purest expression of what the mountain tells us each vintage — each bottle holds only a single grape varietal from a single vineyard.
Our Napa Valley estate wines come from Diamond Mountain in Calistoga, where heritage clones of Cabernet Sauvignon produce black-fruited, age-worthy reds of structure, depth, and patience: Voir Dire, Hawk's Prey, Decree, alongside a plush, structured Merlot. Our Moon Mountain vineyard sits on the Napa-Sonoma border, where Pacific crosswinds and shallow rocky soils give us a savory, spice-lit Syrah and whites that reset expectations — a crisp, mineral-driven Chardonnay and a vibrant, layered Sauvignon Blanc.
Winemaker Andy Jones leads the cellar with precision and patience. Each wine is its own study. What the mountain gives, the wine carries through — beautiful on release, and better with time.
