Hi all, Despite filtering, my beer it's still hazy. Here is what am doing: I'm brewing Kolsch in Speidel-Braumeister 50 liters. After transferring to conical fermentor adding Safale S-33 yeast, leaving for 3-4 days, until FG is constant, then transfer either to 30 liters Euro keg or another conical fermentor inside my cold chamber, where it is kept at temps between 3-5 Celsius (37-41 Fahrenheit) for 3-4 weeks. Then taking that keg (beer) at that temp and push it through 10" filter to another (also refrigerated) keg. I've started with 10 micron filter, no results, changed to 5 microns, nothing. Changed to 3 microns, nothing. Changed to 1 micron and again, no result. Beer seems almost absolutely the same as before filtration. I'm not using irish moss, gelatin or anything similar, since I don't want to add anything in my beer besides water, yeast, hops and malt. So, what am doing wrong!? Any thoughts appreciated! TNX!
