Pascal Potaire and Moses Gadouche of Les Capriades are known as "Les Rois du Pét-Nat" (the Kings of Pét-Nat) in France. Their expertise on the subject makes them a reference for winemakers who want to learn to raise and handle of cuvée of natural bubbly.

For the La Bulle Rouge, Pascal uses only Gamay "teinturiers", aka Gamay that has both red flesh and red juice, with fine bubbles and a nose of red fruits and fresh raisins, with beautiful acidity and a dry finish.
