The FAQ listed Chartreuse as similar to absinthe. It's moderately popular over here, particularly as a shooter to get the birthday boy off his tits as quickly as possible. The best description I've heard of the taste is "grass clippings and methylated spirits," which is not too far wrong. It's 55% alc./vol, but hits pretty hard...it seems to hit harder than 151 rum (at least 76% alc./vol), but that might just be my imagination.
I like it
Absinthe has recently been allowed back in Australia, but I haven't had an opportunity to try it yet, and I'm not sure if the stuff you can get here is 'real' absinthe.
