HappyFace Beek Quadrupel from Stadsbrouwerij De Koperen Kat is a robust quadrupel aged for two months in oak casks previously used for Barbados rum. This Delft-based brewery, established in 2011, brings depth and warmth to the style through careful barrel maturation.

The rum barrel aging imparts warming sweetness with almond notes and a pleasant alcohol warmth. The beer displays a full body, dark ripe fruit character, and a restrained bitterness that provides balance. A serious quadrupel for those seeking complexity and character in their Belgian strong ale.
