I just recently learned that I could bottle from a keg. I've got everything I need and experimented a little. I know I have to lower the CO2 pressure. So now I'm looking for additional tips/tricks/knowledge/information on "how to". I want to minimize waste, overflow, and get the bottles filled w/ liquid. When doing this do you use something sanitary under the bottles to "trap" the overflow and have drinkable excess? Actually anything you can tell me is both welcome and appreciated ... (caviat: as long as you aren't leading me astray so you get a good laugh later )
