I pitched as instructed into the fermenter four days ago. Just looking into the fermenter the beer looked clean. Kegged yesterday and am drinking it today. First 6oz was quite clear. Second was more clear. Third kolsch glass is bright as in "last beer in the keg" bright!
I am convinced it works. Furthermore, the beer at 3 weeks tastes conditioned; more like 6-8 weeks along in the conditioning process.
