Spencer Roloson produces wines from California vineyards that have drawn assessment from major critics including Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter. The winery's portfolio centers on distinctive varietals: La Herradura Vineyard Syrah, a single-vineyard expression of Shiraz that shows the depth characteristic of the variety, and Noble Vineyard Viognier, capturing the aromatic white potential of its grape. Palaterra, a field blend of Valdiguié, Syrah, and Carignan, demonstrates the winery's approach to blending Old World varieties within a California context. These wines reflect the winery's focus on varietal expression and site-specific character drawn from its California sources.
