so i got the new issue of brew your own and checked out the article about "upgrading" my bucket. has anybody tries this yet? i'm mostly interested in attatching the ball valve. i'm not worriied about not having to siphon, but i like the spigot idea for testing the gravity. i figure it would be easier and risk less contamination if i can just turn the spigot to get a sample rather than remove the lid and stick something into my wort to take a sample. what do you guys think? am i risking any sort of contamination?
