Doppelbock or double bock is a stronger version of traditional bock that was first brewed in Munich by the Paulaner Friars, a Franciscan order founded by St. Francis of Paula.
Bockbiers are strong beers that can be traced to the town of Einbeck Germany, circa 1250. They were originally spontaneously top-fermented dark beers primarily made of wheat. Einbeck is also one of the areas responsible for the propagation of lager yeasts that have become commonplace in the modern world.
