IJsbok from De Proefbrouwerij is a robust bock at 9% ABV, crafted using the eisbock method where the beer is frozen and concentrated to intensify flavour. De Proefbrouwerij, founded in 1996 by Dirk Naudts and Saskia Waerniers, has grown into a respected contract brewery based in Lochristi-Hijfte.

This bock delivers a full, malty character with deep caramel and toasted grain notes. The elevated alcohol content brings warmth and richness, while fermentation brings out the traditional character of the bock style. A beer for those who appreciate bold, malt-forward profiles.
