Appellation
An appellation is a legally defined and protected geographical indication used to identify where the grapes for a wine were grown; other types of food often have appellations as well. Restrictions other than geographical boundaries, such as what grapes may be grown, maximum grape yields, alcohol level, and other quality factors, may also apply before an appellation name may legally appear on a wine bottle label. The rules that govern appellations are dependent on the country in which the wine was produced.
History
The tradition of wine appellation is very old. The oldest references are to be found in the Bible, where wine of Samaria, wine of Carmel, wine of Jezreel, or wine of Helbon are mentioned. This tradition of appellation continued throughout the Antiquity and the Middle Ages, though without any officially sanctioned rules. Historically, the world's first exclusive (protected) vineyard zone was introduced in Chianti, Italy in 1716 and the first wine classification system in Tokaj-Hegyalja, Hungary, in 1730.
