From a young couple, non-interventionist vintners Lise and Bertrand, who tend their 25 small vine parcels by hand without chemicals, comes this thoroughly dry, gently sparkling Pétillant Originel, a bubbly style from Montlouis, often called Pétillant Naturel, or Pet’Nat. Pétillant Originel, which won AOC status in 2007, must be absolutely natural, nothing added. It is illegal to add sugar or yeast at any stage of the wine’s production, although both are required in Champagne.
