Widely acknowledged as the first 'tripel' in the world, it was based on a recipe by Henri Vanderlinden, master-brewer of nearby Witkap in Brasschaat. He was then acting as an advisor to Westmalle.
The word ‘tripel’ makes reference to the fact that ingredients are used in quantities larger than usual. It is a strong, predominantly blond beer with a strong taste of malts and/or hop bitters. You can tell the Westmalle Tripel from the Dubbel by its label, which looks antique and yellowed, and the bottle cap in the same colour stamped with the brewery’s initials.
