So I've been lagering now at 33 degrees for about three weeks. Fermentation is done and the marks were hit and a sample tasted great. I ferment under pressure and I noticed that I still have a lot of yeast and such in suspension floating around. I'm going to filter this beer but I would have thought that 3 weeks at 33 degrees would have cleared this beer right up a la cold crash. Is this not the case with lagers?
