Grutte Pier Brouwerij in Leeuwarden has crafted an ambitious quadrupel that matures for eight months across four distinct barrel types: maple syrup, beer, bourbon and sherry. This multi-barrel ageing process builds considerable depth and character into the finished beer.

The glass reveals a dark ruby red with a beige head. The nose shows vanilla, wood and red fruit, while the palate delivers roasted malt, whiskey and bourbon notes. This is a beer of many layers: the inherent richness of the quadrupel style is amplified by the contributions from each barrel type, resulting in a complex, full-bodied experience with a warming finish.

This edition is limited—only 3130 bottles of no 27 were brewed. The beer reflects Grutte Pier's innovative spirit, named after the legendary Frisian folk hero.
