Question on Carbonation
|
|
Hello,
Why does the priming sugar added during bottling cause carbonation, but not the sugar frm the wort during fermantation?

During Fermantation, the yeast has eaten all the fermentable sugar.. The sugar add at bottling is to give the remaining yeast food so they can fart in your bottle and cause the carbonation.
The Sugar during fermentation is carbonating, that's where you get your airlock bubbles from.

CO2 is produced during all phases of fermentation, in huge amounts while you beer is in the primary fermenter. It's simply allowed to escape to atmosphere.

...and not absorbed by the brew...thus, no carbonation.

I will never see carbonation the same way again.

About half of the fermentation sugars become CO2 and half C2H5OH. Yeast farts and vomitose!

yeah, yeast are nasty when you think about it. I've always thought of it as urine, not vomit.
We let fungus float around farting CO 2 and pissing alcohol, right in our beer. then we line up to drink it.

I think I'm more partial to the piss...
But it sure tastes weird without the farts!!
Oh and - If you could seal your primary fermentor, the beer would carbonate then. But you would have to use a vessel that could handle some serious pressure.

Reminds me of why I drink beer instead of water. It has to do with the way fish procreate in the streams.
