Grutte Pier 539 is a milk stout brewed by Grutte Pier Brouwerij in Leeuwarden, Friesland. Founded in 2014, the brewery has grown into the leading craft beer producer in the region. The 539 delivers a full, creamy body with pronounced roasting and chocolate character throughout the nose and palate.

The aroma shows roasted malt and chocolate notes. The flavour mirrors this intensity, balanced by malt bitterness against the beer's smooth body and mild sweetness. The finish is clean and satisfying.
