The Charles Quint beers refer to the historical figure Emperor Charles V. Born in Ghent, he spent his youth in Mechelen in Belgium. However, as becoming of a real Belgian, Brussels was also very dear to his heart.
It is fitting that he is considered as one of the greatest emperors ever. His empire was eventually so great that people used to say that 'the sun never set on it'. Furthermore, he was also an ardent beer lover. During his distant voyages he always brought along his own cask of beer!
