Kwak is a top-fermented beer. It is dark amber in colour with a beautiful white head. It has a deliciously malty flavour and a slight hint of bitterness can be detected. Kwak is brewed using three different malts and also involving sugar candy. The special feature of this beer is that it is served in a glass with a very particular shape, the stirrup cup. According to the brewery, the glass was created this way so that coachmen were able to hang it on the coach so that they could drink from it without having to get down.
