Default What Does Filtering Do???

Wow,
Thanks everybody. Some really good suggestions here. I'm thinking, the
cold stabilization idea may be the best for me. I may also bottle in 22 oz.
beer bottles so if I do have some blow outs, it's just a cap, not a glass
bottle that explodes.
Thanks again.
Nate
