The Neuzelle Kloster Brewery (Neuzeller Klosterbräu) is located in Neuzelle, Germany, and is best known for its Neuzeller "Anti-Aging-Bier".
Helmut Fritsche purchased the Neuzeller brewery in 1992, which has been producing beer commercially for over 400 years, and is situated on the grounds of a 12th century Catholic monastery.
The "Anti-Aging-Bier", which, in addition to the four cardinal ingredients of beer, adds spirulina and flavonoids in order to, supposedly, increase health and longevity, was first marketed in February 2004, and claims to have double the anti-oxidant effect of other beers. However, the German Beer Brewers' Association isn't entirely willing to label these drinks beers, as their contents differ from those original Reinheitsgebot ingredients.
The brewery also produces a locally successful Schwarzbier, Pilsner, Bock, cherry beer, energy beer, a beer specifically developed for bathing, and a berry-flavored soda used in making a Potsdamer.
