Aaltje Kraak is a brown ale from Brouwerij Brouwersnös in Groenlo, Netherlands. This beer emerged from an inventive brewing process: a single base recipe of 2000 litres was split into five distinct fruity variants. The result is a 6.3% ABV brown ale that showcases the brewery's experimental approach.

The name Aaltje Kraak reflects this creative spirit – a beer born from one foundation but expressed in multiple forms. It demonstrates how Dutch breweries blend tradition with innovation in their craft.
