What makes Capriades so amazing? Well, they manage to combine the best elements of Pet-Nat and Champagne in a way that I've never seen anyone else pull off. They are made like most Pet-Nats, with the secondary fermentation occuring with no additives. The bubbles occur because the wines are put in bottles while there are still some unfermented sugars. However, Moses and Pascal of Les Capriades were not only pioneers of natural sparkling wines, but also the pioneers of disgorging their Pet-Nats, i.e., shooting out the spent yeast from the bottles to make a cleaner, clearer sparkling wine. It's common in Champagne, but was not the norm for Pet-Nat, at least until other winemakers started tasting what Pascal and Moses were up to.
