Wines bearing the PGI Retsina of Attiki (ΠΓΕ Ρετσίνα Αττικής) designation can be produced from all the ampelographic zones throughout the entire prefecture. The climate is classified as hot Mediterranean and is particularly dry, especially during the summer season. Excluding a small part of Attiki on the westnorthwest border with the neighboring Boeotia, the rest of the Attiki peninsula is surrounded by the sea. The cool sea-breezes, blowing inland from the South Euboean, the Saronic and the Corinthian gulfs mitigate the heat, thus creating a number of different microclimates, ideal for viticulture.
Most of the vineyards for the production of PGI Retsina of Attiki (ΠΓΕ Ρετσίνα Αττικής) are located in the coastal zone of Mesogaia. This area is located in the eastern part of Attiki and overall displays the hottest and driest climate in the prefecture. The majority of the vineyards are trained in the gobelet style in order to cope with the extremes of the climate. The old vines are a significant feature of this region and result in wines with greater concentration.
