Visitor FAQs

Do you require reservations for tastings and experiences?
While we do our best to accommodate walk-ins, we highly encourage making reservations to ensure you can experience the awesomeness of Gundlach Bundschu.

How do I make a reservation for a tasting or experience?
Reservations can easily be made online HERE or by calling 707-938-5277, 9am-5pm for personal assistance any day of the week. Tasting reservations are available from 11:00am – 4:30pm daily (November – April) or 11:00am – 5:30pm (May-October). Your reservation will be confirmed via email. Please note guests will be given a 15 minute grace period after the reserved time before the reservation is cancelled. Please call if you are running late.

Our tour experiences run daily Th-M at 11:15, 2:30 or 3pm. For more information on these experiences please check HERE.

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

Yes and no. The Bacchus Bar in the tasting room 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. We also reserve a few Bacchus Club tables in the Vista Courtyard for seated tastings, from May – October. They are available on a first come first serve basis, you and a guest are complimentary and additional guests are 25% off for tasting. Food is available for purchase. But if you want to take part in one of our more formal tastings, or one of our tours, please do 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.

Are children allowed at the winery and can they come on a tour?
Anyone under 21 years of age visiting the winery must be accompanied by an adult. For our experiences, children must be at least 12 years of age.

Are pets allowed?
Well behaved dogs are allowed and must be on a leash at all times.

Can we picnic on your property?
Yes, we can accommodate picnic groups up to 8 people; there are tables in the Picnic Arbor and on Towle’s Hillside as well as picnic blankets for sale. All tables are first come, first served. If you have a group of 8 or more, picnic reservations are required. Please contact our Hospitality Department at or 707-939-3005.

What is your cancellation policy?
We ask that you please cancel 24 hours before your reservation to avoid cancellation fees. Fees vary based on experience booked. We understand your travel plans may change, please call us to cancel your reservation as soon as you can to avoid incurring fees. If you need to update your party size or adjust your time, please cancel your existing reservation and rebook.

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.

Do you offer promotions for large purchases of wine?

We are so glad you asked. We have temporary promotions all the time (get on our email list!) but regardless of what’s going on, we offer certain deals 365 days of the year. We always honor discounts of 5% off 6 bottles or more, 10% off 12 bottles or more and 15% off 24 bottles or more. If you purchase multiple cases (12 bottles = a case) you also receive a shipping break. The first case is full price, the second is half off, and the third (and beyond) is $12 per case ($20 for states with restrictions). Both the case discount and shipping discount are automatically applied at checkout and do not require a coupon.

Can I use your shipping promotion to send wine to my home state when I’m visiting?

Maybe. Standard shipping promotions are not applicable to orders going to AK AL AZ AR HI IN KY LA MS UT. If direct shipping is available we can apply 50% discount to your rates. For states with restrictions, please contact the Direct Sales Team at 707.938.5277 or at for additional information on travel time and exact shipping costs.
