Ondeugende Gappie is a craft tripel brewed by Stadsbrouwerij Vos in Elburg, named after Gerrit 'Gappie' Vos, the family's founding entrepreneur. This beer departs from classic tripel conventions, instead delivering a fresh, full-bodied expression with fruity and malty character.

The nose reveals malt with citrus notes. The palate is fuller and more substantial than a traditional tripel, with pronounced fruitiness balanced by soft, refined bitterness. The finish lingers with gentle bitterness, lending the beer a sophisticated complexity.
