This supposedly happened during the Winter of 1890.

A brewery worker in Kulmbach forgot to bring in a barrel of bock beer during a very cold winter’s night.

Naturally the beer froze and split the barrel wide open.

The Brew master was livid and ordered the worker to drink some of the non frozen liquid as penance.

This liquid had much of the water removed through the freezing process and was excellent.

This is the legend behind the origin of the “Bayerische G´frorne” or Eisbock
