Visitor FAQs

Do you require reservations for experiences?

Reservations aren’t required but are highly recommended, especially Friday through Sunday which are our busiest days.


How do I make a reservation for an experience?

Reservations can easily be made online HERE or by calling 707-938-5277, 9am-5pm for personal assistance any day of the week. Our hours of operation are 11pm- 5:30pm Monday-Sunday. Your reservation will be confirmed via email. We are happy to extend all guests a 15 minute grace period after the reserved time before the reservation is canceled. Please call if you are running late.

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

We recommend making reservations so we can give you the best experience. However, you’re always welcome to drop by and we will do our best to accommodate!

How many people can you accommodate for an experience or tasting?

We accommodate groups of up to 8 people for our Rhinefarm Tasting Experience. For groups larger than 8, please reach out to our private events team at

Are children allowed at the winery and can they come on a tour?

We’re thrilled to welcome guests of all ages to Gundlach Bundschu! If you’re bringing someone under 21, please ensure they’re accompanied by an adult. Kids of all ages are always welcome to join our tasting experiences and most events. While we don’t charge a tasting fee for children, for seating purposes, we might need to include older kids in our headcount. Additionally, please note that for safety reasons, children must be at least 12 for our tour experiences. Children on tours will be charged 50% of the adult price. Also please note that due the nature of our working winery and farm, those under 18 must always be with their party. We appreciate your understanding and look forward to hosting your family!

Are pets allowed?

We absolutely adore our furry friends here on Rhinefarm. We welcome well-behaved pups on leashes to join in on the fun for tastings. We ask that you keep your dogs home for tours, events and concerts. To ensure everyone’s enjoyment, we kindly ask that all dogs remain on a leash held by an adult during their visit. If any doggos are feeling a bit too rambunctious and start causing a ruckus, we may have to politely ask them and their humans to take a breather. Thanks for your understanding and cooperation in keeping our space enjoyable for everyone, both human and canine alike!

Can we bring a picnic to your property?

Unfortunately no, we offer a wide variety of picnic supplies at our bars and Marketplace as well as other seasonal fares. 


Do you allow large groups on property?

Yes! For groups larger than 8, please reach out to or submit a request via our event form here. For our regular Rhinefarm tasting experiences, we can sit a max of 8 per table. We strongly recommend booking groups larger than 8 with our private events team as we can’t guarantee that multiple Rhinefarm tasting groups booked together can sit next to each other.

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.

What is the difference between GUNBUN and Gundlach Bundschu?

GUNBUN is our long-term nickname that inspired a new brand launched in 2023. GUNBUN wines include a Pinot Noir and Cabernet Sauvignon that we source from sustainable vineyards across Sonoma County compared to our Estate Gundlach Bundschu wines which are primarily sourced from our Regenerative Organic Certified Estate, just outside the town of Sonoma. Our GUNBUN wines are made with less new oak and are meant to be enjoyed immediately, whereas Gundlach Bundschu wines are more complex and ageworthy. You can find GUNBUN wines across the country at stores like Target, Total Wine, and other grocery stores and restaurants. Gundlach Bundschu wines are primarily sold through our Bacchus Club, tasting room and website, but may be available in fine wine shops and restaurants. Check our wine finder for more info on where you can find GUNBUN and Gundlach Bundschu wines near you.
