Prospice produces Cabernet Sauvignon and Bordeaux blends from Walla Walla Valley, the acclaimed red wine region of southeastern Washington. The winery's portfolio centers on structured, age-worthy wines built from the valley's signature Cabernet Sauvignon, supplemented by Petit Verdot, Cabernet Franc, and Merlot. BDX, a Bordeaux-style blend, and the single-varietal Phinny Hill Vineyard Cabernet Sauvignon represent the winery's core offerings. Wine Enthusiast, Decanter, and Wine Advocate have rated Prospice's releases, with BDX and Phinny Hill Vineyard Cabernet Sauvignon earning particular recognition among prestige critics. The Walla Walla Valley's warm days, cool nights, and well-drained soils create conditions suited to ripe, balanced Cabernet-driven wines with the structure to evolve in bottle.
