Is stirring valuable? If there was a lot of froth, then it was fermenting fine. I suspect that you didn't have a real great seal on the fermenter, so whatever CO2 was coming out didn't have to go through the lock. When you replaced the lid after stirring you got a better seal. I once did a lager that gave me no bubbles, and no head either, for over a week. I was about ready to toss it, figuring if it hadn't started yet it was sure to be contaminated. A gravity check showed about a third of the starting value, so it must have been fermenting slowly all along. -don perley Return to table of contents

It is present in Pilsner Urquell in spades. My wife once likened this to the smell of manure, not to attack it but rather to attempt to describe it. There is a similarity. (It tastes like horse shit, but in a pleasant way. ?!?) Assuming, though, that it's not the Saaz hops, lets talk about I.M. I've been meaning to ask about it myself. I use it in my grain beers; it's suppossed to improve the kettle break. It's so cheap I use it even though I'm not convinced that it's doing anything. But if I felt it were doing harm....
