Matias produces Pinot Noir and Chardonnay from the Sonoma Coast, a region defined by cool maritime influence and the structural precision it imparts to wine. The Sierra Mar Vineyard Pinot Noir and Rosella's Vineyard bottlings—both the Pinot Noir and Chardonnay—represent the winery's focus on single-vineyard expression. Pinot Noir from this coastal terroir typically shows the varietal's characteristic elegance: red fruit, silky tannin, and the mineral tension that cool-climate viticulture develops. The Chardonnay, grown in the same maritime-influenced conditions, expresses the richness and complexity the variety achieves in Sonoma Coast's diurnal temperature swings. These wines have been evaluated by Wine Enthusiast, Wine Advocate, Decanter, and Wine Spectator.
