The fizz in a brewski

While drinking some of my Becks Premier Light beer (only 64 calories, which technically if you drink it, according to Aaron, makes you a fag) I got to some thinking, why does beer have fizzles, otherwise known as carbonation?

I’m sure there was a scientific explanation to the fizz, probably a by product of some part of the brewing process. However, I had no idea where, nor why in this advanced time ot fermentation arts we would continue to keep the fizz from beer alive.

Is there a reason for it? Does it serve some purpose? Personally, I think we keep the fizz because its fun. Few things are better than a big old burp after downing a few cans of suds.

Here is a website with some more information on beer fizz, and the finer aspects of brewing it:
