Default What's that smell?!

I have an all-grain lager fermenting at 48 F in my chest freezer. It's actively bubbling away and is about at high krausen or maybe just a little passed. I used WLP830 (German Lager) yeast. It has that great sulfur aroma, but if I really get my head down in the chest freezer (without losing consciousness) there's an acrid (but somehow pleasant) odor that burns my nose! Anyone know what that is? It's almost estery, but I was surprised at how it burned my nose and took my breath away.

That there is CO2.

Pop a cold 7-Up. Pour it into a glass without ice and take a whiff. It'll give you the same suffocating burn.

Sounds like CO2 build up and the smell of your beer fermenting. Your chest freezer doesn't allow much of the co2 to escape and since its heavier then oxygen it contains almost pure co2 and will burn if inhaled.

We have a big 7'x3'x3' incubator at work, kept at 5% CO2, when you open that thing you get a big nose full of it. Yeah, takes you breath away, literally.

That yeast will throw a lot of sulphur with the co2. Enjoy it. It is supposed to smell that way.

Thanks for the responses everyone. I just thought it had to be more than CO2. CO2 is an odorless gas so why would it burn my nose?

I think that yeast is the same as WY2308. And if it is, then a diacetyl rest will be in order before you rack to secondary.

Yes, that's part of my regimen. Even if it could do without, I try to do it anyway... just to have the yeast clean it up and ensure fermentation is really complete before lagering.

Yeah, me too. I do a rest anyway. Don't hurt.
