Theorem Vineyards

Theorem strives to create wines that express the unique character of the site and soils in which they are grown. Owners Kisha and Jason Itkin are partial to wines made from mountain fruit, which led them to the mountain estate vineyards they own in the Diamond Mountain and Moon Mountain District AVAs. The couple's philosophy aligns perfectly with that of their winemaker, Thomas Rivers Brown, who has crafted Theorem wines since the company's 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.

“In vino veritas.” That’s the philosophy at Theorem Vineyards, one of the most enchanting vineyard estates in all of Napa Valley. Nestled on the northern slope of Diamond Mountain in Calistoga, Theorem Vineyards houses one of the most significant collections of historical buildings in Napa Valley.
