Grutte Pier was the largest and strongest man in the world in his day. With his huge sword he beheaded six Dutchmen in one fell swoop. The strength he needed came from his love for his family, friends and Fryslân. There are also stories that he fed his power with a special drink from a picturesque Gallic village. This magic drink has medicinal properties and would strengthen life. The alchemists who made these drinks were also the source of the very first recipe for the Frisian drink Beerenburger. The ingredients of these drinks are used in this beer. Elixer is a Frisian hero Stout with Boomsma Beerenburger and is so powerful that you have to taste it with caution.
