Löwenbräu is a traditional German beer with a rich history. It's one of the six breweries originally included in the Munich Beer Purity Law (Reinheitsgebot) of 1516, which stipulated that beer could only be made from water, barley, and hops. Löwenbräu produces several varieties, but its most well-known is Löwenbräu Original, a classic Märzen or Oktoberfest beer.
