The mountainous and elevated vineyards occupy a greater percentage of vine cultivated areas in Greece. In these areas we find almost the entire production of PDO wines, sometimes in flat plains with fertile soils and sometimes on infertile slopes. Typical examples of these vineyards are those of Zitsas and Metsovo, Amyndeon Achaia, Mantinea and some vineyards in Samos, Nemea, Pezon, Kefalonia, Rapsanis and other areas.
In mountainous and elevated vineyards, altitude plays an important role by moderating the climate of each region that reduces the daily temperatures, making it ideal for the multitude of vine varieties to flourish. When vineyards are on slopes, the orientation of the vines plays an important role because of the amount of sunlight they receive. Generally in Greece, due to the hot winds during the summer, southerly orientations are usually avoided because it can affect production.
Mountainous or elevated vineyards have several advantages such as reduced loss of soil moisture, larger intervals of cloud cover, higher levels of rainfall and cooler winds. All of this results in better performing vines, especially in this warm climate, which facilitates the proper ripening of the grapes and their harvest under more suitable conditions.
