About Us

Sonoma Portworks is the only winery in Sonoma County that specializes in ports and after-dinner wines, and one of only a handful in the entire state. As a pioneer in the industry, we like to discover what’s possible—whether that means using an unusual grape to make a port or creating unique flavor combinations in our after-dinner wines.

Made with love by hand (and foot)

Our certified organic and sustainable petite sirah and petite verdot grapes are harvested by hand from the Heringer Family vineyards in Clarksburg. The Heringers have proudly worked their vineyard land for five generations.
Instead of using a propane forklift we move the bins in our cellar using a hand-powered pallet jack. We then use five-gallon buckets to move the must through the portmaking process by hand. Using a handmade press specially designed for us, we press the grapes by foot for our award-winning ports and after-dinner wines and age them in recycled barrels.
The pomace left after pressing is distilled into our grappas at Stillwater Spirits next door. Whatever remains after distillation is recycled back into the vineyard.

Pairs well with life

Part of the Sonoma Portworks tasting room experience is sharing our food pairing discoveries with you. Our ports and after-dinner wines pair perfectly with a variety of cheeses, chocolates and desserts. And we’re more than happy to show you how to recreate the magic at home.
We’re always on the lookout for new ways to explore how our ports and after-dinner wines can bring fun and flavor into your life!
