Greetings from Cologne!
This is a fantastic city if you have never been. Gorgeous historical buildings, including one of the greatest cathedrals I have ever seen. But more importantly - lots of beer! There are 20 local brweries that all brew Kolsch as near as I can tell. And pubs / beers gardens everywhere showing them off. However, interestingly, although mny beers between 950 and 975 were Kolsch, 975 was in fact Kulmbacher Eisbock, a 28% "starkbier". Although it packs quite a punch alcohol wise, it did not taste that strong, with a sweet taste, frothy head and dark colour more reminiscent of strong Belgian beers.
