How about beer?Jason wins the prize!
Well, there isn't really a prize other than the satisfaction of knowing that you were the first to figure it out. Jolly good.
I ran across it while looking for some other chemical information. It was the Molecule of the Week on Chemstry.org.http://www.chemistry.org/portal/a/c/s/1/home.html#
"Beer flavor is a complex balance of sweetness from sugars and bitter from the humulones in hops (Humulus lupulus) flowers. When wort (unfermented beer) is boiled, humulone molecules rearrange to form the more soluble isohumulones (one example shown here). Isohumulones retard bacterial growth and contribute to beer's bitter flavor."
