Hey Zymurgrafi, thanks for the link. Lots of good info. I think I am finally beginning to understand all of this stuff. Going to be brewing my first batch ever tonight, an american pale ale. I'm only going to use a primary, and I was really confused about how long to keep it in there, but now I know why everyone suggests about 3 weeks versus the 1 week that the kit tells you, which is good cause I gotta save up some more bottles! Thanks again.
