What was the name of the Benedictine monk who legend has it invented Champagne?

You're thinking of Dom Perignon....WRONG! This is a common misconception. However, a group of monks did create it at the Abbey of Saint Hilaire near Carcassonne in 1531. It was called Blanquette de Limoux and it was sold in small cork stopped flasks.

The most recent scholarship now attributes the first production of sparkling wine to the English.
