CO₂ is a product of fermentation and does not need to be added to beer. Sodapop, yes, but not beer.

This was very confusing to me - I drink bottled or canned beer; but I think they’re referring to draft beer:

Maybe their fermentator is broke. Either that or nazis stole it. Aren’t they once again responsible for any and all evil taking place?

Yeast shortage. There can be no other answer.

Bingo!! Saccharomyces cerevisiae does its thing for beer and champagne. AP is fake news for the uninformed. How did they not know this, or was it intentional?

That is one way to “condition” beer and give it fizz. Add a little sugar when it is bottled and the remaining yeast will eat the sugar and nicely pressurize the bottle and give the beer its fizz and head.

But then the bottle will have a thin layer of spent yeast on the bottom and most brewers don’t want that.

Professionally made beer is usually micro-filtered and there is (virtually) no yeast left, so pressurized CO2 is used instead to provide fizz.

I agree. I’ve made a few thousand gallons of beer, and you don’t have to add CO2
