Cold Stabilization

Cold Stabilization – the process of cooling the wine that causes tartaric acid to form tartrate crystals, also known as wine diamonds.

WHY DO WE DO IT?

Well, as fun as wine diamonds sound, most people would prefer that they weren’t in their wine. They are completely harmless and have no taste. Oddly enough, crushed tartrate crystals are the same thing as cream of tartar, which makes snickerdoodle cookies taste better.

We put all of our white wines through cold stabilization. For 2 weeks before bottling, the wine sits in the tank at 30 degrees. The copper pipes freeze, as well as the outer coat of the tank.

Our primary objective is the safety of our guests and our staff, while providing a relaxed and enjoyable experience. Our abundant outdoor spaces prove ideal for safe distancing as we continue to create memorable experiences with you!

Outdoor tastings are by reservation, 7 days a week from 10am-5pm (last reservation at 3:30pm).

 We follow procedures established by Sonoma County and the State of California.

Please Reserve online by clicking on the “Visit” tab on our website. Several options are available for members and guests. Our maximum group size is six people per reservation. We ask that you review our Updated Visitation Policy prior to making your reservation.
