The Kasteel beers have inspired the innovative degustation beers that go under the name of ‘by Kasteel’. Cuvée du Château has all the elements of a bottle-aged Kasteel Donker, using exactly the same ingredients and without any additives. The result is a young beer with the full – madeirised – aromas and flavours of a mature Kasteel Donker. The brewer had been searching for a refined madeirisation with a certain degree of oxidation to develop fruity aromas adding to the flavours of sherry and port and touches of caramelised and roast malt and bread, without increasing the alcohol content.
