Dom Pérignon, a Benedictine monk, is widely believed to have invented the champagne. As a cellarer (cellar master) at the Abbey of Hautvillers in the Champagne region of France, he contributed many important innovations to the wine-making process that eventually led to the creation of champagne, including the use of cork stoppers and more precise blending techniques. However, it is important to note that while Dom Pérignon was undoubtedly an influential figure in the development of champagne, the drink as we know it today was not solely his invention.
