Proprietary potent classic French high proof multi-herbal monastic liqueur of the green variety. Only three Carthusian monks know the formula of 130 herbs and flowers for the 110 proof Chartreuse at any given time. It is still produced today (now in Voiron) on monastery property as it has been since 1764. It was spawned by the more concentrated and intense Elixir Vegetal, and has itself since spawned a yellow variety (in 1838). Called for in many cocktails, notably the Widow's Kiss.
Generally available. Produced and sold in France. Distributed world-wide. Available for on-line ordering in some markets.
