When did beer traditionally start becoming carbonated?!
Answers: I'm pretty sure monks that brewed it in the dark ages did not have access to any kind of carbonated water, maybe in the rare case of natural spring water but the carbonation wouldn't last through the brewing process. So where did the carbonation come from on the worldest favorite and oldest alcoholic beverage?
Wait, theres 2 types of carbonation in beers today.
The most common type is called "forced carbonation." They don't add carbonated water (although this would explain Bud/Miller's existence), instead they add CO2 gas to the brew during bottling.
The less common, and AUTHENTIC (ie, Monks), type is called bottle conditioning. You put a little sugar in the bottling bucket (if you homebrew) called priming sugar, and the remaining yeast will eat this IN THE BOTTLE. As you know, yeast convert sugar to alcohol and CO2. Thus, carbonated beer.
Beer is carbonated during the fermentation process, not using carbonated water. Additionally Lambics are carbonated by adding sugars or yeast in the bottle.. I don't mean to laugh but did you really think they used carbonated water?
if you look at the formula of how alcohol is made through fermentation, you will see CO2 as a byproduct. It gets released into the beer, then we drink the beer. We drink yeast excrement.
