Contrary to popular misconception, the namesake of the famous brand didn’t invent champagne. But Perignon, a Benedictine monk who worked as cellar master at an abbey near Epernay during the 17th and 18th centuries, did have quite an impact on the champagne industry.
In Perignon’s day, sparkling wine wasn’t really a sought-after beverage. In fact, the bubbles were considered to be something of a flaw, and early production methods made producing the wine somewhat dangerous. (Imprecise temperature controls could lead to fermentation starting again after the wine was in the bottle. If one bottle in a cellar exploded and had its cork shoot out, a chain reaction would start.) Perignon helped standardize production methods to avoid these explosions, and he also added two safety features to his wines: thicker glass bottles that better withstood pressure and rope snare that helped keep corks in place.
