Grutte Pier Brettune No 16 is a Dubbel from Grutte Pier Brouwerij in Bartlehiem, Friesland. This beer results from a distinctive process: a single batch of base beer spanning 2000 litres is divided across different vessels, each developing its own character. The Brettune No 16 is a blend of barrels 23 and 24, built from Grutte Pier Dubbel and Tripel with natural yeast and wild yeast strains. Natural maturation in wooden casks lends this beer its characteristic complexity and fruity depth.

At 6% ABV, this is an approachable yet flavourful Dubbel that embodies the brewery's philosophy: beers full of character, brewed with passion and simplicity, straight from Bartlehiem.
