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).
Gin is a flavored white spirit. All gin is flavored with [J]uniper berries, and often other ingredients too. Unlike liqueurs, where flavorings are added to the distilled spirits, gin is made by re-distilling the spirit with the botanicals. The name is an English shortening of Genever, the Dutch word for juniper. Vodka is one of the world's most popular distilled beverages.
