Wine Selection

As seekers of the truth, we strive to create wines that express the unique character of the site and soils in which they are grown. We are partial to wines made from mountain fruit, which led us to the mountain estate vineyards we own in the Diamond Mountain and Moon Mountain District AVAs. Our philosophy aligns perfectly with the viewpoint of our winemaker, Thomas Rivers Brown, who has crafted Theorem wines since our founding in 2012. Thomas’ philosophy of letting the site dictate the way a wine is produced has made him one of Napa Valley’s most respected winemakers. His wines have earned the highest acclaim, including more than twenty-five 100-point scores in Wine Advocate.

  • Voir Dire

    Voir Dire is the flagship wine of Theorem Vineyards. Produced from the oldest vines on our Diamond Mountain estate, this 100% Cabernet Sauvignon is a complex, captivating and timeless wine.

  • Hawk's Prey

    Hawk's Prey is a Cabernet Sauvignon from our Diamond Mountain vineyard. The young vines in this block give us a wine similar in flavor profile to Voir Dire; however, Hawk's Prey is more vibrant, youthful, smoother, and more approachable at a younger age.

  • Merlot

    Our Diamond Mountain Merlot comes from a one-acre block our family planted in 2014. From the moment this wine touches your lips, it shows power, structure, and personality. Our Merlot tastes amazing now and will continue to evolve for years to come.

  • Syrah

    Our 2018 Syrah comes from a vineyard at the top of Moon Mountain District at 1,600 feet of elevation. The grapes are treated with warm days and cool nights. It's silky, voluptuous, and rolls over the palate with fine grained tannins and focused acidity.
