Rows of grapevines grow in a vineyard under a clear blue sky, with green hills and a distant mountain in the background.

Our Vineyards

Every wine starts with a vineyard site. Here are the farms we work with and why each one matters.

We source from organically farmed, family-owned vineyards across California — from the Central Coast up to Mendocino. In 2023 we became owners of Fox Hill Vineyard, the first site we farm directly. Every other vineyard is a long-term sourcing relationship, most going back a decade or more.

Our home base

Fox Hill Vineyard

After a decade of sourcing Italian varieties from this site, Chris and Bridget purchased Fox Hill in 2023. Planted with twelve Italian varieties on rocky redvine clay above the Russian River, it is also the source of Broc's estate olive oil and fruit for our syrups and preserves.
