Always to Napoleon's time, Pauwel Kwak was a brewer and the owner of the 'De Hoorn' Inn in Dendermonde.  Mail coaches stopped there every day. But at that time coachmen were not allowed to leave their coach and horses to have their thirst quenched along with their fellow passengers.  As a result, the inventive innkeeper had a special Kwak glass blown that could be hung on the coach.  In this way, the coachman had his Kwak beer safely at hand.  Today Kwak is one of the few remaining historic Belgian beers and is still served with respect for tradition in its original Kwak glass.  Recognizable, special and just as idiosyncratic as the taste of the beer itself.
