Which invention is credited to Dom Pérignon in the history of champagne making?

• A. Basket press
• B. Cork stopper
• C. Glass bottle
• D. Malolactic fermentation

Answer: (A)

Cork stopper is the invention often associated with Dom Pérignon in champagne history. While cork closures were used before his time, he became legendary for promoting and refining the use of corks to seal bottles, which helped retain the internal pressure and maintain the wine’s sparkle. The other options aren’t connected to him: the basket press was in use prior to his era, glass bottles existed long before, and malolactic fermentation is a later-development process not attributed to his innovations. So the cork stopper is the closure most commonly linked to Dom Pérignon in the champagne narrative.
