Default When does autolysis begin?

I've had a batch in primary for 30 days. When am I screwed?

A lot of it depends on the health of the yeast at the beginning. Did you pitch in a bunch of happy, health, sugar chomping monsters, or were they flacid, half dead, trub-encrused bug food? A month is fine if you have happy yeast at the beginning. Pitching crapped out yeast is asking for problems.

I've never seen autolysis except when trub is left sitting for a couple months. If the brew is left in the fermenter, it doesn't seem to happen. I've left a melomel in the fermenter for 18 months & it still smells fine. One of those factoids that will never die.

My pitching was healthy. I'm glad to hear that I'm not screwed

I'm not an expert in off flavors at all but I think my last batch of pale ale has a yeast autolysis aroma. It tastes fine, just has a bad yeast smell. I have a feeling I overstressed the yeast. I took a slurry from my blonde, kept it in the fridge for 10 days, pitched into 10 gallons of amber, then racked 10 gallons of pale directly onto the cake. I just think the number of dead cells crept up on me which is why yeast washing is important. So. I agree that it's not how long it sits.
