krausen

[johnsonbrew]

This is the first time I have brewed with a larger primary vessel and I was curious about the krausen. I have always used a 5 gal glass carboy primary, but it was suggested to go bigger to avoid losing so much volume of beer during the aggressive fermentation process. So I tried a 6 gallon plastic carboy and have noticed very little volume loss in the beer, but there was also no krausen blow off in my blow off tube. All the krausen fell back into my beer. Is this a problem? Will it have any affect on the flavor of my beer? The aggressive primary duration seemed to last bit longer than usual, although I used a different yeast strain this time, Wyeast 1056 as opposed to Safale 05. Any advice or ideas on what happens in this case?

You're fine. There was less in the blowoff tube because it didn't reach as high. It will fall back into the beer and you won't even notice it.

Knock on wood, but I have never had krausen go into any of my blowoff tubes. So obviously it has all gone back into my beer. No issues.

It depends on how healthy the yeast pitch was,& how close to wort temp the yeast hydtrate or starter was. If it's within 10 degrees,it'll take off like mad.
Sometimes it just doesn't blow krausen due to lower fermenter temps. No worries either way...

I like to think it isn't my process, but my insistence on fermenting at the very bottom on the yeast's preferred range.

Who knows? Maybe I really suck and my yeast is in terrible shape and that's why I haven't had blowoffs. Like I said, I prefer to think it is my control.

At any rate, it sounds like OP has some healthy yeast in most batches.

It won't affect the flavor of your beer any more than normal. I almost never have a blow-off (only seems to happen when I only have an air lock on) Anyways, the yeast is doing it's thing either way, what is normally blown off, really isn't that much considering everything else that's going on in the beer.

Like I said,lower temps can keep it from blowing off krausen like crazy.
