Here's the official absinthe "Industry Circular" from the United States Department of the Treasury, Alcohol an Tobacco Tax and Trade Bureau, usually shortened to "TTB". Dated October 16, 2007, it is probably as good a date as any to celebrate as the beginning of real absinthe's return to the table as a licit, not illicit, drink.
This circular is just chock a block full of bureaucratese like "pursuant" (does anyone use this word in normal conversation?), "revoked by operation of regulation" (huh?) and "certificates of label approval" (with its helpful acronym, COLA). They seem to be more concerned with the artwork on the label than the contents of the bottle, because you certainly wouldn't want an image "of hallucinogenic, psychotropic, or mind-altering effects", which hearkens back to Lance Winters' quote about "You get all that from a monkey?". Still seems a little vague to us, but hey, if keeping psychotropic images off the label means easier access to some good absinthe here in the US, we're all for it here at inAbsinthia.
Be sure to also check out the TTB's process for thujone screening. Maybe you could do this at home! Perhaps we'll try it out in inAbsinthia's deep cellar laboratory.
