Green Chartreuse is a distinctive herbal liqueur with a vibrant green color, produced by Carthusian monks in the French Alps. It is known for its complex flavor profile that includes notes of herbs, spices, and flowers, derived from a secret blend of 130 different plants and botanicals. With an alcohol content of 55%, it is one of the stronger liqueurs available, making it a potent and flavorful addition to various cocktails.

In the context of cocktails, this herbal liqueur is often used to add depth and complexity to drinks. Its unique taste can enhance classic cocktails like the Last Word, where it is mixed with gin, maraschino liqueur, and lime juice, or the Bijou, which combines it with gin and sweet vermouth. Due to its strong and distinctive flavor, Green Chartreuse is typically used in small quantities to balance other ingredients while imparting its characteristic herbal notes.
