I love it when my airlock gets dirty, that's how I know the yeast is happy!

I did a german wheat with wyeast 3638 on saturday and look at it today...





I just rinsed out the airlock with tap water. Didn't even bother with sanizer.

....or the fermenter is too small for the volume of wort fermenting.

I would agree with this if it happened for every fermentation.  But if it happens <10% of the time, then there has to be a different explanation, or an additional explanation.  My opinion.

Absolutely.... wort composition, yeast strain, pitch rate, temp, etc... all contribute to fermentation volatility.

(maybe I missed where he said it only happens 10% of the time. )

3638 needs at least 25-30% headspace; it produces the mother of all krausen. Anything smaller than 7 or 8 gallons is "too small" for a 5 gallon batch of that stuff.

He didn't, that's my bad.

I guess I'm still a bit twitchy because this unexpectedly happened to me recently.   :)

oh ok, so my 7.5 gallon carboy is too small for a 5 gallon batch?

You should be good under a lot of circumstances. Just not the one in the photo.

I personally don’t have an issue with blowoff.
I routinely ferment 5.5 gal in a 7 gal fermenter. When i get some yeast in my blowoff jar i just shrug it off ...there are a lot of variables.

No problem.

What is wrong in the photo? Are you trying to tell me my beer won't be good?

Absolutely not. The outcome of the beer has nothing to do with blowoff.

I’m just saying the photo shows a vigorous ferment that would have benefited from more headspace if blowoff is a concern. Like I said, i just shrug it off. It’s no biggie.

Either that or a blowoff tube.

Didn’t Mark Twain say it’s not the size of the fermenter it’s the size of the beer in the fermenter? or something like that ;)
