About the Cavern Club Our Cavern club costs nothing to join, and will save you plenty. Imagine paying wholesale pricing. 25% off each bottle of wine you purchase, and if you purchase five or more cases, you will receive an extra 5% off your order. Club members always receive a 25% discount on wine purchases, and 10% off gift items at the winery. Four times a year receive four bottles of wine. You may pick up your wine or have it shipped to your door. (Shipping is extra.) Call 530.620.2402 to join, or click here for a printable membership form. Or, for more info, send an email.
