Before the German Reinheitsgebot, in 1516 - beer was not explicitly brewed with water, malt, hops & yeast. In fact the Reinheitsgebot was as much a ban against certain substances & adjuncts as it was a government instruction to brewing beer. Until then it was common practice to use a variety of different spices & plants instead of hops to flavor and prolong the shelf life of the beer. Some of the adjuncts that were used even had anesthetic & toxic effects.

Grut beer has roots in many cultures and each culture had its own “special ingredients”: Egyptians (Mandrake based), Native Americans (Corn based), Arabian Tribes, Gaulles, Germanic Tribes and the Vikings.

Grut beer became especially popular during the Middle Ages in Germany in the regions of Westphalia & Lower Saxony close to the borders of Belgium & Holland. During this time the ingredients for beer were very expensive, in particular hops.

Professor Fritz Briem's interpretation of a traditional Grut Bier is spiced with Lorbeer (Bay Leaves), Ingwer (Ginger), Kummel (Caraway), Anis (Anise), Rosemarin (Rosemarie) & Enzian (Gentian). It is brewed with water, wheat & barley malt, “pollinated wild hops” and fermented using top fermenting yeast.
