How much science is behind some of the ideas we have about beer? These sound convincing, and we’re inclined to believe them, but we’ve never really seen any evidence, as such:
- If you pour beer with too big a head, the hop oils will come to the top and disappear (“migrate”).
- Beer spoils more easily in clear bottles because of the action of light.
- Artificially carbonated beer tastes noticeably different from naturally carbonated beer.
We’re going to be asking some brainiacs of our acquaintance to give us their views, but we’re also interested to hear of any evidence you know of to confirm or deny any of these, or of any other theories you’d like to prove/debunk.
As a starter for ten, I’ve got this nagging feeling that, just as sea salt is still sodium chloride however you package it, surely carbon dioxide dissolved in water is the same stuff however it got there?
