The Klootzakske is named after the "bollocks" the friends of this brewery play on each other. Especially in the run-up to their annual friends' weekend; it is a tradition in their group to cross the organizers as much as possible.

A beer was brewed especially for this weekend. In the meantime, the friends did not sit still. The list of pranks became quite long: incarceration, garbage blockade, sabotage, kidnapping, graffiti, ... But the icing on the cake was "stealing" the beer at the brewer's. Fortunately, a reclamation was avoided by smuggling the beer in after all, labeled "Klootzakske."
