I’m a Bacchus Club member, do I need to make a reservation?

Yes and no. The Bacchus Bar in the tasting room and outdoor Bacchus Lounge on weekends, is our informal walk-in experience for members so no reservations are needed for a quick drop in or just to come pick up a shipment. Please note space is limited and on a first come, first serve basis. If you want to partake in one of our tours or formal tastings, including our Vista Courtyard Tasting or our Historic Tasting, please make reservations so that we can be sure to treat you like the rock star that you are.

How many people can you accommodate for an experience or tasting?
We accommodate groups of up to 8 people. However, we have many options for groups larger than 8. To speak with someone regarding tour or tasting options, please contact our Hospitality Department at or call 707-939-3005.

What is your return policy?

At Gun Bun, we have a Happiness Guarantee. We want you to enjoy every purchase and stand behind that promise. We will replace or refund you for any bottle of wine that is damaged, flawed or that you find unsatisfactory within one year of purchase. By law, we cannot accept returns of alcoholic beverages unless the product is corked or flawed. If your shipment is damaged in transit, we will do our best to send a replacement as quickly as possible (subject to inventory availability). Please note that this return policy applies only to wines purchased directly from the winery and does not apply to wine purchased from wine retailers or restaurants. We will also happily refund or exchange unworn and unused merchandise. Please contact us at (707) 938-5277 or email to review options for your purchase.
