The specific style of Billecart-Salmon champagne is due to Jean Roland-Billecart. At the end of the 1950s, he introduced a method of fermentation in which – among other things – the temperature does not exceed 13° C. This slows down the fermentation process, allowing all delicate aromas to fully develop. The long aging on the lie (the sediment) that follows gives the wine a unique clarity and purity. The result is fresh champagnes, with a lot of finesse and fine bubbles. It is not for nothing that Billecart-Salmon is one of the top ten most appreciated champagnes and is the favorite of sommeliers in top gastronomic restaurants.
