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. Trignac XII is the successful marriage between Kasteel Tripel and cognac. Barista Chocolate Quad unites the worlds of coffee, chocolate and beer. Our brewer regularly experiments with new By Kasteel formulas. Follow our innovations!
