Temperatures of Ale beer fermentation

[shanek17]

hey there, so Iv successfully brewed my first pre hopped extract ale beer and they turned out better than expected! my roomates also agreed. However this batch fermented at high temperatures around 80F. So this batch I have going now i put in the basement so it should be around 65-70F, im hoping this will help the overall appeal of the beer. So far the beer has been fermenting for 15 days and im assuming that its fermented dry now but my question is this. Is it best to leave the beer downstairs in the cooler temperatures or bring it upstairs to warmer temperatures well it undergoes its conditioning. My basement is roughly 63F and now that its done fermenting there wont be any extra heat being produced from fermentation so im wondering if it will become to cold and effect the beer!

The basement temps are good for fermenting. just leave it till it settles out clear or slightly misty. bottle,then put in a dark place upstairs where the higher temps will get it to carbing & conditioning at a normal rate,which is about 70F. Too cold & they have trouble carbing ime.

Once in bottles get.it.to where its 70F and leave alone for at least three weeks before chilling one for a week and then pouring into a glass for drinking. As for fermenting temperatures the ambient is not the same as fermenting temp. We're talking about the temperature OF the fermenting beer, not the room its sitting in. A fermometer will help give you an idea of the temp inside the vessel. Also, different yeasts will have different temperature ranges. Some even produce different flavors, or esters, at different temperatures. Read up about the yeasts you're using before you use them and keep them in the correct temp range.

Ambient temp has a direct effect on ferment temps by means of convection. Swamp coolers,etc by the same means.

 

[Golddiggie]

But fermenting beer temperatures will always be above the ambient temp. Even the ambient in a fermentation chamber will be below the brew fermenting temperature. A beer fermenting temp can be as much as 10F above the ambient temperature. Do not look at ambient and assume the fermenting beer is at the same temperature.

For bottling, 70 is where I leave my bottles (my upstairs closet). Then after 3 weeks I move to my basement (around 60) for storage. My wife recently did a science experiment for a class involving yeast activity at different temps. 1 gallon starters were made with 5g of US-05 (The control was not given any yeast). They were placed in different areas with different temps and monitored to FG. The one in the basement (60F) looked the best, cleared the most, and smelled the best.

All temps are room temps, not temps in the fermenters.
