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. It was on display at the brewery for some time. Geif Coroge is often referenced on older lambic-related websites as a beer brewed and bottled by Cantillon.
