Rhinefarm is for the whole pack! From vineyard strolls to tasting room hangs, we’re always happy to have a few extra paws around. Bringing your best furry friend along? Snap a pic and tag us! We love a good w**ery dog cameo.

Our Mystery Case Sale has made its eerie return. (Cue spooky ghost noises)⁠
⁠
What’s inside? That’s the mystery. We’ve hand-selected a pack of delicious w**es, but you won’t know exactly what’s lurking in the box until it lands on your doorstep! Don’t let these scary savings disappear into thin air!⁠
⁠
Shop the sale at the link below through October 31

Nothing spookier than a cave tour beneath Towle’s Hill. 👻⁠
⁠
Go underground for a little Rhinefarm history, six generations of Bundschu stories, and a curated flight of estate-grown w**es. Who knows what you’ll discover around the next corner?⁠
⁠
Book your cave tour and see for yourself!

You know what they say! The more, the merrier! ⁠
⁠
Settle in for our Rhinefarm Tasting: a flight of estate-grown w**es, a few seasonal bites (if you’re hungry), and hosts who feel more like friends!

Another day, another state! ⁠
⁠
It’s another Forehead Chronicles with Hernan! He’s been racking up the miles lately, taking GB from Minnesota, Illinois, Wisconsin and Ohio to Missouri, Connecticut, Massachusetts, New York and New Jersey.⁠
⁠
Between distributors, sales reps, retailers and customers, there’s always a good story to share, a new favorite spot to discover or an unexpected little piece of Sonoma waiting around the corner. And honestly, we love seeing just how far Rhinefarm reaches!⁠
⁠
Swipe through to see if you recognize a few of these spots. And if not, tell us where we should head next. We’re always looking for an excuse to stop by.
