Straffe hendrik Quadrupel, launched in 2010, is an intense beer, dark in colour and full in taste. The sophisicated blend of special kinds of malt give the beer a complex character, combining a delicate dryness with hints of coriander, dark fruits, anise and roasted chestnuts. The palate finishes is a syrupy taste. The refermenation in the bottle creates a living beer that will evolve over the years.
