We are open for tastings in our Historic Stone Cellar on Friday, Saturday and Sunday!

Our Purpose

We believe in the power of community, the sanctity of the soil, the inspiration of collaboration and the notion that all voices deserve to be heard. We stay committed to doing the right thing in service to our land, our people and our customers.

Protecting the Land

SUSTAINABILITY CERTIFICATION

Only 10% of Napa wineries have dual Napa Green Certifications. We believe in being good neighbors and responsible stewards of the land. Our sustainability practices replenish our natural resources, improve air and water quality and protect our ecosystems and wildlife habitats.

Freedom and security are precious gifts that we, as Americans, should never take for granted. We must do all we can to extend our hand in times of need to those who willingly sacrifice each day to provide that freedom and security. While we can never do enough to show gratitude to our nation’s defenders, we can always do a little more.

Gary Sinise, Founder and Chairman of the Gary Sinise Foundation
