As you can see from the subject line, the gases that are escaping my air lock stink. It smells like rotten egg.
This was an extract with specialty grain (munich, chocolate, crystal, and biscuit) recipe. I used Williamette hops for bittering and Tettnang for 20 min and then again at flame out (both in hop bags). The yeast was American Ale yeast (1056) Wyeast.
Temp of wort at yeast pitch 24C. Temp of my yeast starter 22C. Ambient temp of room where primary is located is 18C.
Lag time: 30 hrs (which is significant, I think, given the starter).
Yeast: seems obvious given the lag time. The yeast I used was in the fridge for a while (1 month) as a starter. I had planned to use it on a batch back then but something came up. I could dormant the yeast cells in the fridge.
Two days before brew day I took the starter out of the fridge and carefully poured off the top liquid into another vessel, and left it in a dark room to warm to room temperature.
The day before brew day, I fed the little guys some light DME and then again on Brew Day. The starter 'looked' active enough.
Now. I've read about poor yeast health, petite mutants and all that – I don’t fully comprehend – but I'm almost certain that my yeast handling is the culprit (probably in fridge too long).
Is this beer ruined? (the smell is… well… difficult to miss).
Does anyone have experience with this?
Do you think extended conditioning in the secondary will save the beer?
The primary is still pretty active at this point. I’m waiting for it to settle before evaluating on its way to the secondary.
Sorry about the long winded post – I just wanted you to have all the information.

Beer has always turned out just fine, and I don't secondary. Does it still smell at least somewhat beery? I'd be willing to bet your beer will be just fine...
Hi Goulaigan, what do you mean you don"t secondary? you go direct from primary to bottling? what does it do to beer? what does secondary really do to your beer? sorry, Newbie questions. =)

I believe this has been debunked. Leaving your beer undisturbed in a single vessel for an equal length of time as a combined primary/secondary protocol should actually result in clearer beer, in addition to decreasing the risks of oxidation and infection.
