Beer Duchesse de Bourgogne.

The name of the beer is meant to honour Duchess Mary of Burgundy, the only daughter of Charles the Bold, who was born in Brussels in 1457 and died in a horse riding accident in 1482. Like all Flemish red ales, Duchesse de Bourgogne has a characteristically sour, fruity flavour similar to that of lambic beers.
