Absinthe is a high percentage alcohol ranging from 40-80% fermented from the plant Artemisia absinthium (wormwood)and often flavored with Anise (aniseed) and Fennel (these three ingredients are often called the “holy trinity”) it is naturally green in colour, but can also be colourless. The nick name “The Green Fairy” comes from it commonly being referred to as La Fee verte in literature. The drink is said to have significant mental and hallucinogenic effects and has been associated with crime and murder throughout history.
The process of most alcohol production is due to the fermentation of sucrose (C12H22O11) into ethanol (C2H5OH). Absinthe involves primary distillation to the colourless form and a secondary distillation where the plant is steeped and the traditional green colour is returned, due to chlorophyll extraction during this secondary process.
