Dineen produces wines from Columbia Valley in Washington, a region defined by its continental climate and deep alluvial soils. The winery's portfolio centers on Bordeaux and Rhône varieties, reflecting the valley's capacity for both structured reds and aromatic whites. Heritage Red, a blend of Cabernet Franc, Cabernet Sauvignon, and Shiraz, demonstrates the region's ability to ripen dark-skinned grapes with complexity and balance. Condriesque White pairs Roussanne and Viognier—a nod to the Northern Rhône—capturing the stone fruit and mineral character those varieties express in Washington's climate. Vintner's Blend, built from Shiraz, Cabernet Franc, and Cabernet Sauvignon, rounds out the core range. Wine Enthusiast and Wine Advocate have rated these wines, affirming their technical merit and consistency across vintages.
