Purity Wine Kerfufle Pet Nat 2020

Kerfufle Pet Nat is made from 100% Carignan grown in Madera County, California, from a single vineyard planted in 1915. At over 100 years old, the vines are dry-farmed and head trained, meaning no irrigation and no trellising support — the old bush vines regulate their own yields. Carignan from ancient California plantings is known for vivid color, lively acidity, and expressive red fruit character, all of which translate naturally into the pet nat format.

Pet nat, short for pétillant naturel, is made by the méthode ancestrale: the wine is bottled while primary fermentation is still active, trapping CO2 as fermentation finishes in the bottle. The result is gentle, low-pressure carbonation with fine, somewhat frothy bubbles — less uniform than traditional method sparkling but more expressive of the raw fruit. This bottle carries no added sulfites, no fining, no filtering.

Winemaker Noel Diaz runs Purity Wine out of a warehouse cooperative in Richmond, CA, where roughly 14 natural winemakers share space and equipment. His label philosophy is full transparency: the back label lists every ingredient used in production. For Kerfufle, the ingredient list is one item: grapes. All fruit sourced for Purity is grown organically, a standard Diaz committed to from 2016 onward.
