Organically Farmed in Napa Valley
The Vineyard
Estate vines across Coombsville, Atlas Peak, Calistoga, and Mt. George — tended with regenerative, organic, and dry-farming practices. We are not certified organic. Sheep, deep roots, and living soil shape the wine.
Nurturing Napa Valley Terroir
Our vineyards span Coombsville, Atlas Peak, Calistoga, and Mt. George in Napa Valley. We treat each block as a unique ecosystem, employing regenerative farming practices to build resilience and vitality in the soil.

Organic & Dry Farmed
We believe that irrigation dilutes the expression of the land. By dry farming, we force our vines to send their roots deep into the earth in search of water, resulting in lower yields but significantly higher concentration and complexity in the fruit.
We employ organic practices, eschewing synthetic pesticides, herbicides, and fertilizers — we are not a certified-organic winery. We cultivate cover crops and compost to enrich the soil naturally, fostering a vibrant microbial community beneath the surface.
Sheep-Led Soil Balance
During the dormant winter and early spring months, a flock of sheep roams our vineyards. This ancient practice provides multifaceted benefits: they manage cover crops organically, their grazing stimulates root growth, and they naturally fertilize the soil.
This symbiotic relationship reduces our reliance on tractors, lowering soil compaction and our carbon footprint, while creating a truly closed-loop agricultural system.


Wild Yeast Fermentation
Rather than relying on commercial yeast, wild yeast fermentation allows naturally occurring yeasts from the vineyard and winery to guide the fermentation process. This traditional approach can create wines with greater complexity, individuality, and a distinctive expression of their place of origin.
