IJndejaars is Brouwerij 't IJ's winter flagship, a full-bodied strong ale at 9% ABV that evolves slightly in character each year. The brewery's signature spice blend—coriander seed and licorice—anchors a profile of caramel sweetness, fermentation-driven fruit esters, and warming alcohol.

The aroma is bold and complex, leading into a palate where malt sweetness and spice interplay with subtle acidity in the finish. Despite its strength, it drinks with surprising approachability. Brewed in Amsterdam since the mid-1980s, when the brewery pioneered craft beer in the Netherlands, IJndejaars embodies the house style: characterful, unpretentious, and designed for convivial winter evenings.
