There is an article in the November, 2005 Wired Magazine
entitled "The Mystery of the Green Menace."
I found it quite interesting. It's about a New Orleans analytic chemist who has reverse engineered historic samples of absinthe and has recreated it in a French distillery.
This production was possible because when the EU ergulations were recently recently written, they neglected to mention absinthe, which had previously been banned in all of Europe except Spain.
Among other things, he argues absinthe has only 1% of the level of thujone as has been previously suggested. Thujone is a substance found in the herb Artemisia absinthium
, a major ingredient of the liqueur, and which has been blamed historically for the alleged terrible effects of drinking absinthe.
