I've had some problems with fermentations stopping too soon this winter. Common sense says that temps are too low. However, my fermentation area stays over 66F, which should be in range for the yeast I'm using. I think my son's drumming is doing something to the yeast. If it is loud enough to hurt my ears, wouldn't it be loud enough to hurt the yeast? (or at least to annoy them?) I've moved my fermenter to a warmer and quieter area, but I was wondering if anyone has noticed problems with loud noise impacting fermentation, or seen research on the subject.

No,I play Bach to my yeast lol. If noise was a factor I think the vibration would keep the yeast in suspension longer causing it to ferment out to the lowest possible sg for the yeast and temperture conditions. Perhaps you didn't aerate enough? Must be a reason other than what you are suggesting. Are you AG or extract? What yeast and what OG and FG are you getting? I guess what I'm saying is more info is needed to help you out.

It's hard for yeast to reproduce with there hands over there ears.

Now if some of them had their feet over their ears.............................?

In theory, I guess vibrations at certain frequencies might possibly have some minor impacts by mechanical excitation. But I think that it would be the cause of your stuck ferments is pretty unlikely at this point :-)

If you still want to dig into it, maybe try to identify the resonance frequencies of the cell components and see if you can find it in the drum spectrum :-)

What more details do you have? receips? strains? starters? lagtimes? primary times?

Indeed the bobber is great! I believe it should become the official B&V trollage alert emblem.

No words required . . just the bobber.

All trolls aside I have my drum kit in the basement and the fermenters near by. I've never heard the yeast complain. I've never bothered to ask them either.

I've pilfered quite a few gif files over the years. The "right click" is your friend.

While I'm thinking of it, I gotta pass along a pretty cool thing:

It let's you quickly grab stuff off your screen for putting in an email, or, er, a forum post!
It can be very handy.

I purposely left out the gory details because I think I'll have better results in my new fermenting area (it's only been 2 days, so I don't know for sure). I took over the shower stall in a small under-used bathroom in my basement. I recently discovered that the baseboard heater works, so I now have good control of fermentation temps. But since I changed 2 variables at once (temp + loud drumming), I haven't isolated the single factor that was stopping my fermentations , so I thought I'd ask.

FYI, since I'm a new poster, I should introduce myself. I've been home-brewing for about 6 months with extract+specialty grains. I use 5-gallon glass for primary and secondary. I've made some very good beer before my recent high FG problems, so I'm pretty hooked on the hobby. All-grain is probably in my future, but (correct me if I'm wrong) I don't see a way to work my way up to it gradually, in terms of buying necessary equipment. Since I've been getting away with using a 3 gallon stainless brew pot I already owned, I'd need to buy a bigger brew-pot in addition to a propane burner setup (my electric stove won't cut it), plus mash/lauter equipment, plus wort chiller.

p.s. Does anyone listen to "John Barleycord Must Die" by Traffic when they homebrew?
