 The <unk> produced in the Languedoc is made according to the <unk> <unk> - formerly known as <unk> <unk> , the same method used to produce the Champagne , including a second fermentation in the bottle to <unk> the carbon dioxide produced by the yeast - in the small villages around the town of Limoux . The wines are normally composed of 70 % Mauzac and a 30 % combination of Chardonnay and <unk> blanc . AOC regulations require a year of aging on the <unk> . The <unk> de Limoux , when labelled <unk> <unk> , is composed entirely of Mauzac , undergoes only one fermentation and is aged approximately three months less on the <unk> before the <unk> , the actual date being determined by the moon 's cycle .
