Like most French wines, Calvados is governed by appellation contr�l�e regulations. The "Appellation Calvados contr�lée" area includes all of the Calvados, Manche, and Orne départements, plus parts of Eure, Mayenne, Sarthe, and Eure-et-Loire. The more restrictive "Appellation Calvados Pays d'Auge contr�lée" area is limited to the east end of Calvados département, plus a few adjoining districts.
Calvados should be aged in oak for several years before bottling - look for the phrases "vieilli en chêne" and "vieilli en f�ts de chêne".
