The character of some wines improve greatly with age, whether they mature in barrels, or are bottled. Thus specific terms have been coined for aged wines that are commensurate with the category to which they belong, and the time and manner of aging.
For PDO wines 'Protected Designation of Origin', there are the indications Reserve and Grande Reserve. For white wines the indication Reserve indicates an aging time of 1 year before the release of the product, of which at least 6 months it was barreled and 6 months bottled. For red wine, the aging time is three years, of which at least 12 months inside barrels and 12 months bottled. Similarly, wines with the indication Grande Reserve are aged, the white wines are aged for two years, with a minimum of 12 months in barrels and 6 months bottled. While the red wines are aged for four years, with a minimum of 18 months in barrels and 18 months bottled.
For PGI wines "Protected Geographical Indication" the indication Cava, which refers to an aging time of 1 year for white wines, with a minimum of 6 months in barrels and 6 months bottled. While for red wines the aging is for three years, with a minimum of 1 year in barrels and 1 year bottled.
Sweet wines are given specific indications, when produced by one of the following two methods:
• With added alcohol originating in wine, like liqueur wine. Such wines are characterized as "Naturally Sweet" or "Vin Doux Naturel". Due to the use of alcohol, these wines are "controlled".
• By some natural ways of concentrating grape contents, such as over ripening of grapes on the vine, exposure to the sun (sun-dried grapes) sun-dried or air-dried after harvest. These wines are characterized as "Naturally Sweet" or "Vin Naturallement Doux", while if it is made of sun-dried grapes, can be characterized as "Liastos". These wines may not be sweetened by other means or other methods.
In addition to the indication concerning the geographical locality and the age of a wine, we have information regarding the type of vineyard. Thus, only the wines of Appellation of Origin and Regional wines are given the opportunity to use the terms Ampelon (Vineyard), Ktima (Domaine or Estate), Pyrgos (Chateau), Monastiri (Monastery), Villa or Arhondiko (Mansion). This is only possible if the wine is produced from grapes grown in vineyards belonging to that wine making facility and the wine is made in this holding.
