Thanks for your input digdan. I think that was about the most definitive post I can remember reading against filtering. I can't speak for Kaiser, but my beer comes out remarkably clear, so my methods are sound. The reason I'm looking into filtering the beer is get the last bit of yeast out of the beer; you know, the yeast you can't see, but is there? I'm not fixing any problems as I really have none.
As far as needing. No you don't need to filter, but then there are alot of things you don't need in homebrewing.
You don't
need a magnetic stir plate, a HERMS system, a HBC, a wort oxygen injection system, a brew scupture, a diffuser, brewing software and spreadsheets, a counterflow chiller, a pump, a glass primary fermenter, or even a hydrometer.
You should probably know that these are things that the typical (and not so typical) homebrewer
wants to either make the hobby more enjoyable, easier, or simply to add another toy to play with.
Sometimes you just need to feed the monster! I'm sorry that filtering did not add anything to your experience and I do appreciate your point of view. Brew on!
