But I gave it a try, because it was an organic one from a micro brewery in Cologne I did not know.
Heller is a small brasserie in the south of Cologne. Without any serious prejudices, I had two bottles and was positively surprised: unlike the thin taste of regular Kölsch, this one has a decent character, spicy and a little hoppy. Due to the fact, I had to be the family chauffeur, I switched over to water later the evening. Otherwise I would have stayed with the beer much longer.
But what always happened with Michael and Kölsch, also happened with Hellers the next morning: waking up, I felt like having drunken 10 bottles of the stuff, not just two. This curiosity happens anytime I give Kölsch a try. I won't complain, pointing out the "bad" quality of brewing tradition in Cologne. My explanation: being from Düsseldorf, my body just developed special defence shields for a beer from Kölle ;-)
