Well this thread has convinced me to give it a shot since I am brewing a kolsch with low IBUs. I am going to use 1.5 oz FWH of 2.1% Tettnang and throw in a bit of N. Brewer to get me around ~22 IBUs.
I have decided to go with a more traditional kolsch instead of my 'americanized' version. My brewing has been slowly shifting toward more simple and more traditional which I thought would never happen...
