A Crémant, made using the traditional Champagne method. The grapes were manually harvested and carefully transported in harvesting bins. The juice was gently extracted using a pneumatic press, which allowed 30 to 40% of the juice to be extracted without having to re-press. The juice was then allowed to settle before the alcoholic fermentation, which occurred at a controlled temperature of 18°C. Meticulous blending of the various terroirs and grape varieties was then carried out, with bottling throughout January to encourage secondary bottle fermentation. Aged on its fine lees for at least three years, the Code Rouge was riddled and disgorged according to the Champagne method. This cuvée has all the traditional features of Gérard Bertrand's wines: the emblematic red colour of the bottle and the Alpha and Omega symbols, symbolising the endless cycle of nature which inspired its name 'Brut Eternal'.

Code Rouge is a Blanc de Blanc, showing great finesse and elegance. Almost crystalline in colour, with fine bubbles, this pale sparkling wine has a floral bouquet combined with aromatic notes of ripe pear, green apple, citrus, and a touch of creamy vanilla. It is fresh, with a refined mineral on the palate and a vibrant finish.
