Waterstone produces wines from Napa Valley, the North Coast region synonymous with Cabernet Sauvignon and structured red blends. The winery's Cabernet Sauvignon draws on the valley's signature varietal, while Study in Blue—a blend of Cabernet Franc, Petit Verdot, Shiraz, Cabernet Sauvignon, and Merlot—demonstrates a more complex approach to the region's fruit. A Cabernet Sauvignon Reserve rounds out the portfolio. Wines from Waterstone have been assessed by Wine Enthusiast, Decanter, Wine Advocate, Wine Spectator, and Falstaff.
