In 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 in order to have their thirst quenched along with their 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.
