Beer prior to filtration, I’d tried gelatin + kieselsol for around 2 week now in total at 0.4C:
Using the Sawyer SP-128 Filter:
- The filtered beer definitely tastes different (I am not planning to do this on all my beer)
- I noticed that when I attached this tiny filter in line to a corny keg, it does clog fast (back flushing with clean water does help fix it, but that’s only a temporary fix)! So I’m planning to add a 0.5 micron absolute filter prior to it, in 5″ or 10″ filter housing.
- Because this is sterile filtration (which will remove the yeast), I will add bottling yeast, when bottling and priming.
- Instead of filtering all beer, I’m going to alter my process including taking steps to encourage precipitation of cold break, by chilling potentially to 0C after boiling, leaving for a while then increasing to pitch temp.
