A unit is the measure of the amount of alcohol in a drink. One UK unit is 10 ml or eight grams of pure alcohol. A typical pint of ale contains one or two units, whilst a glass of wine can contain anything from around one and a half to three units, depending on the size of the glass and the strength of the wine.
What is Absinthe? Absinthe is a strong herbal liqueur which is distilled with a great number of flavorful herbs including anise, often partially substituted with star anise, veronica, fennel, lemon balm, angelica, licorice, hyssop, Florence Melissa, and Roman wormwood (Artemisia Pontiac).
Anethole is one of the main flavoring ingredients in several liquors and spirits, including absinthe. In absinthe it helps to form the opaque effect that occurs when water is added to the spirit. 13 times sweeter than sugar, anethole can be used as a sugar substitute. It also has powerful anti-microbial properties, attacking bacteria, yeast, and fungi. It has been found to be effective against insects.
