Who is the Benedictine monk that invented champagne?

The Benedictine monk credited with inventing champagne is Dom Pérignon. He was a cellar master at the Abbey of Hautvillers in France during the late 17th century. While he didn't actually invent champagne as we know it today, he significantly improved the wine-making process, particularly in the production of sparkling wine. His methods laid the groundwork for the development of champagne as a distinct beverage.
