Heineken® launched H41®, a limited edition Wild Lager brewed using a rare 'mother' yeast discovered in the deep forests of Patagonia. Developed over the course of multiple years by the brand's Master Brewer, the new lager has a fuller taste, with spicy notes balanced by subtle fruity hints.

The name H41 is derived from the latitude co-ordinate of the beech forest in Patagonia where this yeast was discovered. The H stands for Heineken®.
