As with all Gueuzes, Hanssens is a mixture of several vintages to produce a lambic which is refreshingly fruity. This is the result of blending different lambics of different ages. The second fermentation takes place inside the bottles and therefore they are stored for minimum six months in constant temperature kept cellars.
Despite being one of the smallest blenderies in Belgium, Hanssens can still claim to be one of the oldest. It has been on the same site since 1895 and there is evidence it was been making beer decades before that.
