Uiltje Tonka Fever is a 10% ABV imperial porter from Haarlem, brewed by Uiltje Brewing Company since 2015. This is a bold, full-bodied porter built around tonka bean as its defining ingredient—an unusual choice that gives the beer its distinctive character.

On the nose, vanilla and tonka dominate, with molasses and wood notes underneath. The palate delivers cherry and honey alongside rich tonka, finishing with a warming, boozy warmth. This is a beer for drinkers unafraid of intense, unconventional flavours and willing to explore the extremes of the porter style.
