Is Yeast Nocturnal ?

[Mutilated1]

Is yeast more active at night time than during the daytime ?

I've got 6 batches in primary right now, and they don't burp all day long except after midnight till about the time I get up in the morning.

I'm starting to think that yeast likes to wake up and be more active at nighttime. Is there anything to this or just my imagination ?

your house may be warmer at night when you are home and turn on the heat. Yeast are not nocturnal.

I didn't think it was that much warmer, but I guess you're right. Either that or the house is quieter at night time so I can hear the burps that I don't notice during the day.

That's the funniest question I've seen in a while!

Well seriously...

I get home from work about a quarter to 7 and check the beer. Look at the temps, watch it for a few minutes to see which ones are still bubbling. Haven't noticed any bubbling for a few days.

And then after wife and kids go to bed and I'm sleeping... "Blurp!" "Blurp!" every few seconds...

From all I can tell the temperature is the same. I've got a thermometer on the thermostat, a thermometer on the shelf near the beer, and most of the fermenters have a thermometer on them too, which is why I was kind of not sure it was the temperature or anything.

Maybe the wife has been drinking your beers all day

... and no yeast aren't nocturnal. They can't sense light.
