Bartholomew Estate Winery

Sonoma, CA

Bartholomew Estate Winery sits on one of California's earliest premium-wine sites — the heritage property marked 'where California premium wine began,' tracing back to 1857 in Sonoma Valley. The property is now owned by the non-profit Bartholomew Foundation and operates alongside a public park on the grounds. The tasting room is open to the public. This is a public-interest heritage estate rather than a family-owned winery; descriptions should carry the non-profit stewardship model rather than a conventional family-ownership frame.
