“It feels very remote out at Oso Vineyard, ... Knowing that any given morning I could be mauled by a Black Bear lends a certain verve and excitement.”

Wilderness Outnumbers Vineyards Here...

...creating a biodiverse patchwork that shapes vibrant, concentrated wines. Its amphitheater-like topography, stone-lined terraces, and rocky, well-draining soils force vines deep into the earth, yielding grapes with intensity and character.

A dramatic diurnal shift—warm days balanced by cool nights—preserves freshness and acidity, producing Cabernet Sauvignon, Sauvignon Blanc, Petit Verdot, and Petit Sirah with firm structure and excellent aging potential.
Three lakes set Oso apart in the dry valley, nourishing the vines while sustaining the diverse wildlife that inspired its name, “oso,” Spanish for bear. In 2022, Adaptation acquired Oso Vineyard to establish a permanent home for its vibrant, flavor-forward wines. Today, it stands as the backbone of Adaptation and a hidden jewel of Pope Valley, uniting natural beauty, biodiversity, and bold, expressive winemaking.

What makes Oso Vineyard special is the diversity of terroir, the crazy different exposures, and the diurnal shifts, which can be a 55°F change from the middle of the night to the peak of the day. It makes growing pretty tough, and I think that’s something special about that ranch, and that the vines can really withstand these extremes.
