In accordance with Governor Newsom’s directive on March 15, 2020, we are closed for tastings until further notice. Please continue to check our website and social media channels for updates.

We invite you to visit our store to explore and purchase our small production wines. We are thankful that we can ship to most states and are offering local delivery within Sonoma County with the purchase of six (6) or more bottles. If you are interested in talking to us before your order, please call Diane at 707-484-5162.

Thank you for your understanding and we look forward to visiting with you soon.
