In those areas, winegrowing zones determined on the basis of the borders of communal municipalities have been established, together with certain restrictions regarding altitudes or natural and artificial limits. With the exception of two areas, varietal compositions are determined strictly on the basis of Greek native grape varieties.
All zones are subject to restrictions as to the maximum allowable yields per 0.1 hectare and various other prerequisites which wines must comply with. Especially AOQS wines, which carry a mandatory characteristic red band on the neck of their bottles, must be produced by wineries located within their winegrowing zone.
In other words, it is not only the grapes which must originate within a certain zone: the wineries vinifying them must be established within that zone as well.
The AOC wines zones – “Controlled Appellation of Origin” (part of the PDO Wines of Greece) are historically and geographically determined winegrowing areas.
AOC wines, which must be vinified by wineries located within their zones, carry a mandatory characteristic blue band on the neck of their bottles, must meet all the prerequisites of AOQS wines and, additionally, have higher specifications as to their content in sugars.
