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).
For the most common distilled drinks, such as whiskey and vodka, the alcohol content is around 40%. The term hard liquor is used in North America to distinguish distilled drinks from undistilled ones (implicitly weaker). Vodka, gin, baijiu, tequila, whiskey, brandy, and soju are examples of distilled drinks.
