In a nutshell: A full and clean Marzen beer from Rothaus Badische Staatsbruaerei in the Black Forest.
The lowdown: Marzen beers are typically brewed in the spring, cool cellared over summer and released in the autumn. They have plenty of body a quite a full malty flavour. Rothaus Eiszäpfle is gently hopped and has the classic full-bodied clean taste.
Rothaus's flagship beer Tannenzapfle is sometimes touted as the world's best pilsner and it's indeed a stunning example of clean, delicious lager brewing. The brewery itself was founded by the abbot of a monastery in the German Black Forest. It was meant to bring prosperity to the region, and has done exactly that. Being entirely state owned after the abolition of the monastery it donates millions every year to the state, while producing near enough 1m hectolitres without ever compromising its world-famous flavour.
