We live in the Rhineland, near the beautiful Cologne and have this holster ordered as a gift for a grill enthusiastic friend. We enjoyed the delicious Kölsch is usually directly from Maurer bottle (0.5 liters).
And this should holstering !!! Nope. Unsuitable. Neither early Kölsch nor Reisdorf, gaff, or any other ... Also no Pils: Jever, Bitburger, Köstrizer ...
The only good thing: Looking for the matching 0.5 liter bottle, we now have an excuse to try many different varieties ...
