Mystery Molecule - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

This molecule is for a liquid found useful by many visitors to RF Cafe.

OK, I'll take a crack at it. Is it Ethyl Alcohol?

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

"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."
