temp of beer in fv

[mattybabsy]

so i started a brew on thursday night- checked the temp of the brew again today and its down at 16 degrees. is this too low for fermentation? I moved it outside to the garage yday and am worried its too cold out there.

its the belgian brupac triple

thanks

16 is a bit low and will be slow, 20 is probably bang on and the reason I say 18 is, a brew produces it's own heat and can jump a few degrees.

I've not been brewing because it is too warm here mid 20s is lovely weather but sh?t for brewing. I need a fermentation fridge

I placed my fv in a container with a about 5 inches water in which i placed a 25w aquarium heater and a digital thermometer with probe, all for a few quid off ebay if anything it is not on in the day with our warmer weather of late but comes on at night in garage to stop temperature variation, its around 22 degrees. it worked fine on my coopers aussie lager and currently i have woodfordes wherry best bitter on the go. from what i read its the temp variation that can give a off flavour. aussie lager in grolsch bottles tangy for first few weeks but now after 5 weeks really nice.

thanks guys! it's been 5 days now with the same beer. I just did a hydro reading- it was 1.20. I'm not sure what the starting reading was cos I didn't have a hydro at the minute. so my question is, is it ready after 2 days of the same reading? or could the yeast have stopped cos it was outside and too cold and therefore needs a stir to get it going and get a lower hydro reading?

on the up side, it tasted absolutely incredible.

Could leave it for a bit longer what fermenting time did it say on instructions I have read that a slow stir could lower the fg ideally to around 1010 but don't get air into the brew at this stage, can you get it to a warmer place around 20-22 degrees ? it may help to reduce the chance of secondary fermenting in bottle after priming.

moved to to a room which is constantly 19. slightly lower than I would prefer- but best I can do. Should I stir it? I'll know later tonight if I'm getting 2 consecutive same hydro reading.

In the winter, before I got a heater, my brews were around 16C, & they ended up with a slightly low final gravity, so they turned out weaker than hoped. After I got a heater, all my brews were bang on FG.

It's a bit too warm in my shed at the moment. It gets like a sauna in there & can be 35C, on the warmest days. But in the winter it's around 10C, if not colder. The house is a constant 18C, so thats the place to be

Keep it around 20C, & you can't go wrong. From my limited experience, below 16C makes it weaker, & over 25C makes it taste like Diesel, so 20 is the magic number
