I was in Austrlia for 6 months where Absinthe was legal. First off, you have to like the taste of anise (that licorice taste in Jager and Sambuka). It's also a pretty high alcohol content; there's normally a number in the name of a good bottle, and this represents the %. I perfer 53%'s to some of the higher 60's/low 70's because there's a lot more in the taste than alcohol.
I'm not one who belives that Absinthe has some psychedelic properties because of the lack or wormwood in most modern stuff, but it's drunk is very euphoric and relaxing. I have had some great conversations on it.
One more thing; don't light it on fire. Please. It's simply a barberic thing to do.
If you want more info, check out http://www.feeverte.net/
, probably the best site on the net for information. It also has some good vendors if you're looking to "get" (yes, it's an illegal import, but many of the good stores will insure against seizure). Here's a few suggestions for you if you're interested.
Francois Guy 45
Any of the Clandestines (mostely 53's)
Un Emile 45
I have had the Emile and Kubler before. The Guy is also highly recommended. I just noticed that the Jades, which are probably the best around these days, have gotten much cheaper. They used to sell for over $150, and can now be found for $75.
