Come See Us Soon

We are nestled on the northern slope of Diamond Mountain in Calistoga on 60 acres of some of the most beautiful land you've ever seen. Blessed with a little fog, abundant amounts of sunshine, and porous volcanic soil, our vineyard is not only stunning to look at, it's talented at crafting rich, memorable, and delicious wines. Currently, we grow mostly Cabernet Sauvignon and a small amount of Merlot.

Our Location:
255 Petrified Forest Road
Calistoga, CA 94515
