Cider (called Cidre in French, also known as "Cider" from English Cider) is the world's second largest fruit wine, second only to wine in terms of production. It is popular in Europe, the United States, Australia and other countries, and is a hot spot in the international beverage market. Cider is a fruit wine made from apple as the main raw material, crushed, pressed, fermented at low temperature and aged. Cider is an alcoholic beverage made from pure fruit juice fermentation. In addition to apple cider, there are also pear cider, peach cider, or fruit wines made from other fruits. Cider is low in alcohol content, ranging from about 2%-8.5% or so.

Cider was traditionally produced mainly in the south of England and in Normandy in northeast France, where grapes are not suitable for cultivation. Many countries have begun to produce cider, and modern Australia has become the world's largest producer of cider with a rapidly rising production of cider, while China has begun to produce cider in recent years.
