Beresan Winery draws from the Walla Walla Valley, a subregion of Washington's Columbia Valley known for its continental climate and ability to ripen Bordeaux varieties with structure and depth. The winery's portfolio centers on Cabernet Franc and Merlot blends, with Viuda Negra—a Cabernet Franc and Merlot blend—leading the lineup. Stone River, a four-varietal blend of Cabernet Franc, Shiraz, Merlot, and Cabernet Sauvignon, demonstrates the winery's approach to layered, complex reds. Tom Foolery, a Cabernet Sauvignon and Cabernet Franc blend, rounds out the core offerings. These wines have been assessed by Wine Enthusiast, Wine Advocate, and Wine Spectator, reflecting the winery's engagement with serious wine criticism.
