Supermassive Cellars is a small, handmade winery in West Seattle crafting wines from Washington grapes with a distinctive focus on texture and mouthfeel. Owner and winemaker Chris MacDonald draws from premium vineyards including Wahluke Slope, Naches Heights, and Umpqua Valley to produce Barbera, Pinot Gris, Viognier, White Pinot Noir, Müller Thurgau, and Chardonnay that prioritize elegance over fruit-forward intensity.
