Hertog Jan Bockbier is a Dutch bock beer that the brewery claims was the first top-fermented bock produced in the Netherlands. This stronger beer follows the traditional autumn brewing season, using fresh hops and barley harvest—a custom with deep roots in German brewing.

The aroma presents rich malt with notes of dried fruit, dates, and subtle roasted character. The palate opens with sweet caramel and malt depth, followed by dark chocolate and warming alcohol. The finish turns dry with a nutty edge, a quality that makes this beer well-suited to cold winter evenings.
