There’s lots of glamour, danger and intrigue surrounding this anise-flavored, green liqueur. That’s probably why it’s called “the bad boy of beverages.” And also probably why it’s been banned in the U.S. and much of Western Europe for nearly a hundred years. During the late 19th century, it was believed that the wormwood (a bitter herb) in absinthe caused insanity and French Symbolist poetry—which, in some circles, could really be considered the same thing. High in alcohol content (75%), absinthe has seen a faddish reappearance in the U.K., where surprisingly, it’s always been legal. However, wormwood-free substitutes like Pernod, Ricard and Herbsaint are thriving among urban bar hipsters everywhere else.
