Each year a new Masterpiece (Meesterstuk) is brewed to honour Saint Maarten the saint of the Haarlem Brewersguild in Haarlem.
This years edition is a oatmeal Quad; the aroma is malty and fruity, due to the chosen yeast in combination with some coriander seeds. A full, rich silky and fruity flavour shows the use of oats and dark malts.
