Prothro Family Wines has captured top honors at the 2025 San Francisco International Wine Competition, earning the coveted Best Cabernet Sauvignon award for its 2022 Signature Release Cabernet Sauvignon. Prothro Family Wines is a boutique, ultra-limited production winery rooted in a passion for handcrafted quality that began over 25 years ago in a humble garage in Los Gatos, California. Today, the winery crafts wines sourced from some of Napa Valley’s most respected vineyards, focusing on balance, nuance, and ageable structure. Their portfolio encompasses classic varietals such as Cabernet Sauvignon and Chardonnay, all produced in small lots available mainly through their Wine Club and mailing list, creating a loyal following among collectors and enthusiasts.

The 2022 Signature Release Cabernet Sauvignon is classic in style: structured, powerful, and brooding, taking time to unfurl its layers of dark fruit, cocoa, graphite, and anise. This vintage exemplifies the winery’s approach to crafting wines that reward patience in the cellar, with bright acidity and firm tannins that promise a long life in bottle. 

With this win at one of the country’s most respected competitions, Prothro Family Wines solidifies its reputation for producing world-class Cabernet Sauvignons that appeal to both seasoned collectors and adventurous wine lovers. Whether enjoyed now or cellared for years to come, the 2022 Signature Release stands out as a benchmark expression of Napa Valley Cabernet.
