I suspect it is because she has tasted a cucumber kölsch that she enjoyed. Maybe more than one ... although how many Cucumber Kölsch beers can there be out there?
Anyway ... I was thinking about what to brew. I thought maybe that a Cucumber Kölsch might be fun to try to make. I asked the Beer Model and she said it was a good idea. She liked it much better than the spruce tip beer idea that I was also thinking about.
So ... it seems to me that a Cucumber Kölsch should be pretty simple. Brew a Kölsch. Add Cucumbers. Not very hard. I've already brewed a Kölsch, which was a big success. My local grocery store sells cucumbers. The only question is how many cucumbers should I add?
