Winemaking & Lots of Fun!


San Giorgio is all about fun with wine. And, it's an event venue like no other. Located within the 140 year old Pierre Biane Winery complex in historic Rancho Cucamonga, San Giorgio celebrates the winegrowing history and heritage of the Cucamonga Valley. Taste and purchase our wines, plan your own event, attend one of ours, make your own custom wine, and much more. All the wines we serve are made by us, in small lots, with great care. And, although we don't make/serve beer, we do make and serve a wonderful Mead wine that will more than satisfy beer lovers. We love sharing our passion for "everything wine"! 



San Giorgio of Cucamonga Winery is not just a winery, it is also an awesome event venue. You can rent our venue for parties, celebrations, weddings, you name it. We also periodically host our own events, such as comedy & magic shows, wine tastings with Karaoke, small live music events, and more. And, our winery is geared toward producing exceptional, small-lot wines and brandy, and educating the public on all facets of winemaking. We help families throughout the Southland make their own wines from their own home vineyards or from grapes sourced by us from premium vineyards throughout California. We love wine. We are passionate about wine. We are passionate about sharing our passion for winegrowing, winemaking, and wine appreciation. Join us!

Totally Different

We have an ultra private room that we call our "speakeasy." We could talk about it here, but it is meant to fly below the radar. Our little room harkens back to the days of Prohibition when booze and fun had to be hidden behind dark doors where Franco the Knife required a passwork for you to enter. Perfect for a girls' night out, a friendly poker party, a bachelor(ette) party, or just a cozy night with friends/family. You'll have to see it to appreciate it. If you can get the password.
