Editing Calvados (section)

==Grades of quality==
The age on the bottle refers to the youngest constituent of the blend. A blend is often composed of old and young calvados. Producers can also use the terms below to refer to the age.

* "VS", ''Trois étoiles'' ***, and ''Trois pommes'' must be at least two years old.
* ''Vieux'' or ''Réserve'' must be at least three years old.
* "V.O." "VO", ''Vieille Réserve'', "V.S.O.P.", or "VSOP" must be at least four years old.
* "Extra", "X.O." "XO", "Napoléon", ''Hors d'Age'', ''Tres Vieille Reserve'' must be at least six years old, but are often sold much older.

High-quality calvados usually has parts which are much older than that mentioned. Calvados can be made from a single (generally, exceptionally good) year. When this happens, the label often carries that year.
