Gerardus Quadrupel from Gulpener Bierbrouwerij is a dark, full-bodied strong ale at 10% ABV that has matured for ten months in American oak barrels from Jamaica. This aging adds complexity and a rich, caramel-forward character with warming alcohol notes.

As a Quadrupel, it delivers dark fruit and spiced esters balanced against the oak influence. The result is a contemplative beer with substantial mouthfeel and a lingering finish—ideal for unhurried enjoyment. Gulpener's approach to barrel aging elevates the classic Belgian dark strong tradition.
