Also, Kolsch is one of my favorite brews I've made. I did an extract honey kolsch last spring. This spring I did two batches of all-grain and added some pilloncillo (mexican brown sugar) to one of them. Super delicious all around.
Are you using the Wyeast 2565 Kolsch yeast or a different one?
Also, I just noticed your location. Congrats on your newly legal homebrew status!
