Absinthe

Absinthe is not strictly a liqueur. It substitutes bitter for sweet. This strong spirituous liquor, so prejudicial to French health and morality, is, however, commonly called a liqueur. Its base is an alcoholate, composed of anise, coriander, and fennel. It is flavoured with wormwood, a species of artemisia, and other plants containing absinthin. It is said to be commonly coloured with indigo and sulphate of copper. In the late 1800s it was prepared chiefly in Switzerland or Bordeaux.
