Absinthe! Cheers mate!

Absinthe is a distilled, highly alcoholic (45%–74% ABV) beverage with a flavor of anise. It derives from herbs, including the flowers and leaves of the herb Artemisia absinthium, commonly referred to as "grande wormwood". The color of Absinthe traditionally ranges from a light yellow to a natural green color but it can also be colorless. It is commonly referred to in historical literature as "la fée verte" (the Green Fairy). Absinthe is not bottled with added sugar and is therefore classified as a spirit. Absinthe is unusual among spirits in that it is bottled at a very high proof but is normally diluted with water when consumed.
Absinthe originated in the canton of Neuchâtel in Switzerland. It got a great popularity in late 19th- and early 20th-century in France, particularly among Parisian artists and writers. Due partly to its association with bohemian culture, Absinthe was opposed by social conservatives and prohibitionists. One of the opposition to the consume of Absinthe was the presence of high levels of thujone, a monoterpene, with a menthol odor, found in the leaves of Artemisia absinthium. Recently chemical analysis with GC-MS, even about old samples of Absinthe, found contents of thujone between 2 and 20 mg/kg, under the limits of 35 mg/kg of the recent EU regulations. This is due to the fact the thujone is extremely volatile compound and that it looses during the dry of the Artemisia absinthium leaves and of course by cutting the head of the distillation of the mix of herbs during the preparation of this beverage. No worries when you drink a good Absinthe, but be worried because it is not easy to find a good one on the market. There are some rules to follow, the famous 5 rules:
It has to be a spirit distilled from a specific mix of herbs (Artemisia absinthium, anise, melissa, coriander and others)
It has to be highly alcoholic (45%–74% ABV)
It has to become opalescent when cold water is added
It has to contain green anise instead of star anise
It has to be balanced in the global aroma
