Observed annually on October 16, this day celebrates alcoholic beverages made from distilled spirits flavored with fruit, cream, herbs, spices, flowers or nuts and often bottled with added sugar or other sweetener.

Liqueurs are often sweet, but rarely aged. Some have resting periods during production to allow flavors to marry.

In the United States and Canada, where spirits are generally referred to as "liquor", there is often confusion over liqueurs and liquors. Liqueurs are usually sweet and often syrupy in consistency, while liquors are not. And liqueurs generally have a lower alcohol content than spirits.

In the United States, liqueurs are sometimes called cordials or schnapps, while in large parts of the British Commonwealth, cordials are fruit-flavored soft drinks. In Germany and Scandinavia, a schnapps is a type of brandy or aquavit.
