We invite you to visit our tasting room on the edge of the Dunnigan Hills AVA. Surrounded by picturesque vineyards, our tasting room offers the perfect setting to unwind and explore our estate-grown, small-lot wines. Enjoy a guided tasting of our latest releases, sip on award-winning varietals, and learn about our sustainability practices from our knowledgeable team.
Whether you're a longtime wine lover or just beginning your journey, we invite you to relax, savor, and make lasting memories with us.
Plan your visit and discover Grindstone—where every glass tells a story. Cheers!
