The stuff worth experiencing happens off the beaten path. Off the beaten path is where it is real. No place embodies this more than Sonoma. And no one has been doing it longer or with more zeal than Gundlach Bundschu.

Named one of Travel + Leisure’s best wineries in Sonoma, Rhinefarm Estate has been owned, farmed and operated by our family since 1858. Our winery is known for our warm people, our cool climate, and our creative spirit. We make approachable, unpretentious wines of outstanding quality. Come on over and visit us for a wine tasting, vineyard experience or live music to get to know our laid-back Sonoma vibe.

We are open every day 11am – 4:30pm for tours and tastings, with the last reservation at 3pm. Reservations are encouraged, especially on the weekends. If you prefer to walk-in, we recommend stopping by on a weekday for your best chance for a seated tasting. Our property is family and dog friendly. Please, no outside food. We offer an assortment of cheese, charcuterie boards and other seasonal fares for purchase.

Winter Cave Tour

Everyday at 11AM & 2PM. Thurs-Suns tours offered at 11AM, 1PM, & 2PM.

Picture this: You are exploring the underground world of Gundlach Bundschu in our wine caves and organic vineyards. First, glass of wine in hand, your wine educator will guide you through our wine cave and tell legendary stories of the Bundschu family’s deep roots in California winemaking history. Taste different wines as your walk will venture outside the back cave doors (weather permitting) to learn more about our regenerative organic vineyard, sheep, old vines, and sustainability practices. The tour culminates with a tasting of our Vintage Reserve Cabernet in our majestic cave dining room. Epic, right? Yeah, we think so, too.

Pinz Excursion

Closed for winter season. Pinz tours reopening in spring 2024.

Climb aboard our Pinzgauer (“pinz-gower”), a Swiss Army transport vehicle, for an off-roading experience across Rhinefarm. Cruise through our regenerative organic vineyards with a glass of wine in hand as your guide takes you on a journey of our history as the oldest family-owned winery in California and what makes our wines so unique. You’ll stop at several spots in the vineyard including an enclave amongst the vines to taste two wines alongside cheese and charcuterie. Back in the tasting room, your experience culminates with a splash of our icon Cabernet, Vintage Reserve. What happens on the pinz stays on the pinz, so if your friends back home want to know, well, they’re just going to have to see for themselves.

Flanked by historic stone buildings and barns, this intimate and idyllic location is sure to be the highlight of your day. Kick back as your experienced and eccentric host guides your group through a memorable flight of five of our wines with light bites.
