Hi , I am having another weird krausen but this time it started in secondary a few hours after racking. I didn´t check FG before racking (error), I believed it was done cos it had a strong fermentation during 2-3 days and was progressively winding down during 8-9 days , a normal fermentation in my opinion. Moreover, I pitched it with a ton of windsor yeast of previous batch (very fresh yeast). My concern is this issue has started 10 days ago and it seems there´s no sign of stopping, I thought a few remaining points at high temperature fermentation wouldn´t hurt beer flavor , but now I am afraid they were not just a few points(maybe fusels issues). I left it alone these last days (vacations)while temperature has reached 80 F cos I thought it wouldn´t last more than 2-3 days to be finished. Im going to have a sample tonight to see what has happened in regards off-flavors . What could be the cause/s ?

I took a sample last night, it has a malty taste at the beginning turning in a quite dry finish. It is still bubbling , krausen is diminishing though. I am a bit worried if I don´t stop fermentation it´s going to get harsh-astringent flavor. Overpitching could be the culprit here, I don´t know.

Do you know where your gravity is now? I don't think overpitching could result in much over-attenuation. Underpitching can result in yeast failing to finish, but the impact of overpitching on attenuation should be marginal if anything. Also, how high did you raise the temperature in the secondary? I wonder if your bubbling activity might be mostly related to CO2 outgassing.
No , I didn´t take a gravity read , room temperature raises due weather , it´s getting warmer here . I couldn´t upload a photo where bottom layer can be showed, it is a big and thick yeast layer for a secondary, so I think there was a high qty. of yeast in suspension at the moment I racked from primary but it wasn´t working(at least is what I thought)
It certainly sounds like your fermentation wasn't as far along as you assumed it was when you racked. I wouldn't lose a lot of sleep over this.
