The German Hassan Rabbit Brewery, located in the southern German state of Bavaria, is one of the largest and oldest breweries in Augsburg, dating back to 1464. Since 1156, the Brewers Association has stipulated that all people who live in Augsburg and want to brew beer are allowed to brew only from water, malt and hops, 360 years before the Bavarian Purity Act was promulgated. It is the region with the largest beer sales in the world and the best water quality in the whole territory, and is known as the "spring city" of Germany. Therefore, it creates the unique, pure and authentic German "flavor" of Hasen-Biere Hassan Rabbit Beer.
