liqueurs 
Liqueurs (French Lehnwort liqueur, from Latin liquor for "liquid") are aromatic spirits with a relatively high sugar content (at least 100 grams per liter). The alcohol content is usually 15 to 40% vol, but there are also stronger and weaker liqueurs, for example Chartreuse verte with 55% Vol or Aperol with 11 or 15% Vol.
