Charles & Charles operates in Washington's Columbia Valley, a region defined by warm days, cool nights, and deep volcanic soils that shape structured red wines and mineral-driven whites. The winery's portfolio centers on Cabernet Sauvignon and Syrah-based blends, varietal expressions that thrive in the valley's continental climate. The Bolt Cabernet Sauvignon anchors the lineup, a wine that has drawn attention from Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff. The Post No 35, a Cabernet-Syrah blend, offers a different angle on the region's dual strengths in both varieties. A Chardonnay rounds out the core range, capturing the mineral precision Columbia Valley whites can achieve. The winery's approach reflects the valley's capacity for both power and balance—reds with tannin structure and whites with acidity and complexity.
