French for “cooperage”, each beer in the series shares one core trait: they were all fermented in oak. Beyond that, the recipes and styles are as unique as the cues they take from nature. Quadrupel Tonnellerie, a barrel-fermented Belgian-style quadrupel with blackberries, is no exception. A style known for being at the more malty, complex and rich end of the Belgian strong ale spectrum, this quad revels in layers of sweet caramel, dark fruit and figgy flavors, and complementary undercurrents of oak. The natural esters from the Belgian yeast compliment the rustic, earthy qualities derived from the barrels and piquant flavors from the fruit for a dynamic flavor profile and mouthfeel that will evolve over time.
