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.
Absinthe: Absinthe is an anise-flavoured spirit derived from several plants, including the flowers and leaves of Artemisia absinthium ("grand wormwood"), together with green anise, sweet fennel, and other medicinal and culinary herbs. Historically described as a highly alcoholic spirit, it is 45–74% ABV or 90–148 proof US. Absinthe traditionally has a natural green color but may also be colorless. It is commonly referred to in historical literature as la fée verte ("the green fairy"). It is sometimes mistakenly referred to as a liqueur, but is not traditionally bottled with added sugar and is, therefore, classified as a spirit. Absinthe is traditionally bottled at a high level of alcohol by volume, but it is normally diluted with water before being consumed. Absinthe originated in the canton of Neuchâtel in Switzerland in the late 18th century. It rose to great popularity as an alcoholic drink in late 19th- and early 20th-century France, particularly among Parisian artists and writers. The consumption of absinthe was opposed by social conservatives and prohibitionists, partly due to its association with bohemian culture.
