Note: this does not refer to the type of headache that comes from drinking too much wine. Panos Kakaviatos (decanter.com) writes:
A Nasa scientist has developed a device that can assess levels of headache-causing agents found in some wines.
Some biometric amines - compounds which occur naturally in some red wine - cause headaches by elevating heart rates, amongst other triggers. The modified amino acid tyramine is a particular culprit.
Now University of Berkeley chemistry professor Richard Mathies - who suffers form wine-induced headaches - has created a device to detect these agents.
Great stuff! Can't wait for it to hit the shelves.
