Pet Nat wine | What is a Pet-Nat?

While pet nats might seem like a hip new fad, the method of winemaking used (called the Ancestral method) is actually one of the oldest for making lightly sparkling wine! Unlike the fully sparkling traditional method wines of Champagne, Cremant or Cava, these wines are produced by a single fermentation (whilst traditional method wines see two fermentations).

The trick lies in the partially fermented juice being bottled, with no SO2 addition. The fermentation then finishes inside that very bottle. As the yeasts convert sugar to alcohol and complete their journey to dryness (leaving a little residual sugar behind) the by-product of carbon dioxide is created and captured in the bottle - voila, bubbles!
