Orange Bitters: Orange bitters is a form of bitters, a cocktail flavoring made from such ingredients as the peels of Seville oranges, cardamom, caraway seed, coriander, anise, and burnt sugar in an alcohol base. Orange bitters, which are not to be confused with the standard Angostura aromatic bitters, are currently enjoying a resurgence among cocktail enthusiasts. It is to be noted that the well-known House of Angostura is one of the producers of orange bitters.
Chartreuse: Chartreuse is a French herbal liqueur available in green and yellow versions that differ in taste and alcohol content. The liqueur has been made by the Carthusian monks since 1737 according to the instructions set out in a manuscript given to them by François Annibal d'Estrées in 1605. It was named after the monks' Grande Chartreuse monastery, located in the Chartreuse Mountains north of Grenoble. Today the liqueur is produced in their distillery in nearby Aiguenoire. It is composed of distilled alcohol aged with 130 herbs, plants and flowers. According to tradition, a marshal of artillery to French king Henry IV, François Hannibal d'Estrées, presented the Carthusian monks at Vauvert, near Paris, with an alchemical manuscript that contained a recipe for an "elixir of long life" in 1605. The recipe eventually reached the religious order's headquarters at the Grande Chartreuse monastery, north of Grenoble. The formula is said to include 130 herbs, plants and flowers and secret ingredients combined in a wine alcohol base. The recipe was further enhanced in 1737 by Brother Gérome Maubec. The beverage soon became popular, and in 1764 the monks adapted the elixir recipe to make what is now called the "Elixir Végétal de la Grande Chartreuse".
