Beer with caffeine

The two Austrians Joris Narath and Anton Krisper, plagued by the consequences of a drunken night out, wanted a beer with the effect of an energy drink. But it wasn't until ten years later, in 2014, that Narath and Krisper bottled their idea in 0.33-liter bottles. The beer is brewed at the Gratzer brewery in Styria.

Eule Bier is Austria's first caffeine beer - tart and quaffable, with hops from Leutschach in southern Styria. 30 mg of caffeine are contained in 100 ml of beer. By comparison, a well-known energy drink has 32 mg of caffeine.

Eule beer with caffeine is also available in Germany.
