Cider
Cider ( ) is an alcoholic beverage made from the fermented juice of apples. Cider is popular in the United Kingdom, especially in the West Country, and widely available. The UK has the world's highest per capita consumption, as well as its largest cider-producing companies. Cider is also popular in many Commonwealth countries, such as India, Canada, Australia, and New Zealand. Aside from the UK and its former colonies, cider is popular in other European countries including Ireland, Portugal (mainly in Minho and Madeira), France (particularly Brittany and Normandy), northern Italy (Piedmont and Friuli), and Spain (especially Asturias and the Basque Country).

In the U.S. and parts of Canada, varieties of fermented cider are often called "hard cider" to distinguish alcoholic cider from non-alcoholic "cider" or "sweet cider", also made from apples.

"Stagecoach and Tavern Days", written by Alice Morse Earle, describes a 16th-century New Hampshire settler proudly recounting "he made one barrel of cider, one barrel of water-cider, and one barrel of charming good drink" from his first apple crop of eight bushels.
