I read about the 'supertaster' status of certain folks who have extraordinarily acute senses of taste and found a test on the internet where they send you a liquid that you subsequently taste. Depending on what you do taste they grade your taste sense.

Has anybody tried this and are there any supertasters on SE? :)
