Beers of mixed fermentation
Versnijbier or blended beer, is brewed by blending old and young beer or mixing beers of spontaneous fermentation with high and low fermentation beers (e.g. Petrus Aged Pale, Cuvée Watou, Vicardin Tripel Geuze, etc.). The most traditional type of this blended beer is the so-called ‘oud bruin’.
