Theorem Vineyards is a Calistoga winery on 60 acres of Diamond Mountain in Napa Valley, where volcanic soils, sun, and cooling winds produce bold, expressive wines. They craft energetic, age-worthy wines with patience and precision under winemaker Andy Jones, picking by taste and keeping lots separate. Custom private tours and tastings offer panoramic views, stunning architecture, and aromatic gardens.
