Here's what the fine print says: Aventinus. The wheat-dopplebock of Bavaria has been known to the most intense and complex wheat beer in the world. This was the case in the past, but not anymore...Recently, Hans-Peter Drexler, brewmaster at G. Schneider and Sohn. Heard stories about some extra special Aventinus resulting from a partial freezing during a cold winter transport in the 1930s. He decided to recreate this classic "mistake" to further concentrate Aventinus in a modern controlled facility. Thus, the Aventinus Eiisbock was reborn prost!
