Cantillon Geif Coroge
Description
According to Jean Van Roy, Geif Coroge was not a beer brewed by Cantillon. Instead, it was a labeled bottle given to the brewery by a patron as a token of encouragement in the 1980's when the brewery, like many other lambic producers, fell on hard times. Geif Coroge is often referenced on older lambic-related websites.
