Kateel Bier aka castle beer is bottle aged in a "castle" that dates back to 1736 in West Flanders. The bottle aging process is usually 6-12 weeks.
Due to the alcohol strength this brew packs a punch and has a heavy malty flavor. Made with tree malts and dry hopped. The beer carries a port like richness and has notes of dried tangy fruit. This however isn't a smooth brew, it has quite a bit of texture at the end.
