Kasteel Rouge is based on our Kasteel Donker. This fruity beer makes a great aperitif on a sunny terrace. It’s certainly a beer for lovers of sweet cherries with an intense aroma of the fruit. The cherries get the better of the malt in the Kasteel Donker mother beer, although it contributes touches of chocolate and pepper to remind you it’s there. It is surprisingly easily digestible for quite a strong beer.
