Alta Orsa Winery

Alta Orsa is a mountain vineyard rooted in the hills above Hopland. For more than three decades, the estate has been farmed with a light hand — no‑till soils, cover crops, and organic practices that treat the land as a living system. Led by winemaker Martin Bernal‑Hafner, the team works with their high‑density estate vines and a few trusted Mendocino and Sonoma growers who share the same farming values. In the cellar, the approach stays minimal so the vineyard and the season can speak clearly, letting the hillside leave its own imprint.
