approach to winemaking


"pét project is about creating wines that are painstakingly simple and as complex as possible using only one ingredient - organically farmed grapes"

- winemaker, Jay Anderson


organic grapes only.

Zero additives. Because we only use one ingredient, we want to make sure it's the best, without the unknowns that come along with chemical inputs.

never fined or filtered.

Fining and filtering can remove the good stuff that gives wine complexity and texture. That's why we don't filter or use fining agents. 

no added sulfites.

While sulfur can be an important part of age-worthy still wines it is not needed in the production of pét-nats.  All our wines contain only naturally occurring sulfites.

always changing.

Experimentation is what we do best. Our lineup is different every year, growing with new varieties, styles, and techniques. 

"Pét-nat has a reputation for being unpredictable and at times a little funky but ... it’s part of what makes them exciting...You can, and absolutely should, check out Anderson’s fizzy selection in Seattle at Foundry’s Pioneer Square tasting room."


" It requires a bit of witchcraft to dial in sparkling wine using the ancestral method. Jay Anderson does it in Walla Walla with a sense of tropicality and without leaving a mess. Enjoy with popcorn topped by a dash or two of truffle salt."

"Pet-nats, often released young, within months of harvest, tend toward vibrance and play. Maybe the bottle gets a little funky. Maybe the maker releases it cloudy. Maybe, like Pét Project’s grüner veltliner, it has delightful, if enamel-stripping, acidity."
