Not Legal Advice: Absinthe contains a lot more alcohol than most other liquors.
Absinthe does have a very high alcohol content -- anywhere between 55 and 75 percent, which equates to about 110 to 144 proof. It makes whiskey's standard 40 percent (80 proof) seem like child's play, which is why absinthe is supposed to be diluted. Absinthe is not a hallucinogen; its alcohol content and herbal flavor sets it apart from other liquors.
Traditional absinthe is made of anise, fennel and wormwood (a plant), and various recipes add other herbs and flowers to the mix. The anise, fennel and wormwood are soaked in alcohol, and the mixture is then distilled. The distillation process causes the herbal oils and the alcohol to evaporate, separating from the water and bitter essences released by the herbs.
The fennel, anise and wormwood oils then recondense with the alcohol in a cooling area, and the distiller dilutes the resulting liquid down to whatever proof the absinthe is supposed to be (based on brand variations or regional laws). At this point, the absinthe is clear; many manufacturers add herbs to the mixture after distillation to get the classic green color from their chlorophyll.
