Dunham Cellars operates in Washington's Walla Walla Valley, a region defined by its continental climate and gravelly soils that yield structured red wines and aromatic whites. The winery's portfolio centers on Lewis Vineyard fruit, where Cabernet Sauvignon and Syrah thrive. The Lewis Vineyard Cabernet Sauvignon expresses the valley's signature character—dark fruit and tannin architecture typical of the region's Bordeaux varieties. The Lewis Vineyard Syrah captures the peppery, mineral-driven profile Walla Walla is known for. A Late Harvest Riesling from the same vineyard rounds the range, showcasing the valley's capacity for both dry and sweet expressions of this versatile grape. Wine Enthusiast, Wine Advocate, Decanter, Wine Spectator, and Falstaff have all assessed the winery's releases, reflecting its standing within the broader Washington wine conversation.
