Trinafour Cellars

Trinafour Cellars is a small, vineyard‑first Mendocino producer devoted to old vines, organic farming, and honest, small‑lot winemaking. Winemaker Alex MacGregor works with some of the county’s most historic dry‑farmed sites, crafting bright, textured wines that let each vineyard speak for itself. From Petite Sirah to quietly expressive whites like Sémillon and French Colombard, Trinafour wines are fresh, food‑friendly, and deeply rooted in Mendocino’s farming tradition, the kind of bottles you discover once and remember.
