So, I tried to re-read this entire thread to find this answer but here's my question! If primary is for fermentation and secondary is for clarification (essentially, NOT fermentation) then if I used a cool/cold fermentation can I leave the secondary fermenters in a different temperature environment, just so they can clarify? Or would this change in temps cause some problem that I'm not seeing? I have a fridge that I've got my primary's in and I'd like to use it for continual primarys rather than having to use it for the same batches in secondary. If that makes sense? Thanks in advance for your thoughts/help! :fro:
Hi August,
Your "cool/cold fermentation" suggests that you are brewing a lager, in which case you should maintain the cold temperature for several weeks after fermentation has finished (lager means cold storage) while the beer ages and clarifies. Even some ale styles, such as Kolsch, are traditionally lagered.
You weren't too specific about the nature of your "different temperature environment" but conditioning an ale at a little higher temperature should be OK. Some people purposely bottle condition in the mid-70's to speed up the bottle fermentation. Once fermentation is complete, temperature becomes less critical.
When I brew an ale, I prefer to leave it in the primary for at least a week after fermentation has completed, then I transfer to a secondary and condition it at around 32F deg. for another week or so. The colder the temperature, the quicker it clarifies.
