High temp ferment in buckets

General Homebrew Discussion

I’ve gone mid-high 80’s before with no problems, but curious if anyone has experienced off flavors from fermenting at ultra-high temp in well-cleaned and sanitized plastic brewing buckets - of course not associated with other brewing faults, such as from chlorinated water, improper pitch rate or yeast health, minimal aeration, lack of nutrients, etc.

So just based on plastic bucket at high temp.

I have a couple buckets temp-controlled holding at 90F (beer temp) for my version of Randy Mosher’s Saison Buffoon using Wyeast Saison Yeast (WY 3724),and just curious of other people’s experience.

FWIW, I pitched at around 92F and have held it at 90F since then.

Sure.  A plastic bucket is no different than any other fermenter in that regard.

Ok. Cool!  I just figured glass (carboy) or SS are completely inert, whereas more pliable (looser molecules?) plastic might just a little bit possibly be more prone to a threshold for flavor impact due to temperature.  Well, below melting point.  :o

I think I’ll RDWHAHB - at least at happy hour.

Food-grade HDPE won’t leach anything until at least 110°C.

Which is 230F.  Cool!  Thanks Sean.

I’ve fermented around 90F in a bucket with no problms.

There are people who install heating elements in buckets and boil in them.
