Oliviada olives grow in an olive grove on a hill in Kalamata, Messinia region. Olive trees bloom and start fruiting in spring. They thrive through summer and the harvest of olives starts in November and ends in February.

Oliviada olives are harvested by a local Greek family while picking them by hand and by using vibrating rakes that gently remove olives off the branches into nests that have been placed under the tree canopy.

At the oil mill, olives are washed in order to remove all foreign matter such as leaves, twigs, stems or other debris to avoid any adverse impact on olive oil organoleptic characteristics.

The clean olives then pass, with their core, into the grinder. There olives are crushed and milled into a paste. The purpose of crushing is to tear the flesh cells to facilitate the smooth release of the oil from the vacuoles.


Malaxing or mixing the paste for up to 45 minutes allows small oil droplets to combine into bigger ones. It is important during this mixing stage to respect a temperature below 27°C (80°F). This manufacturing process is called cold pressure extraction that guarantees the high quality of olive oil.


With a help of centrifuges the oil is separated from the rest of the olive components. The oil is then left in steel tanks where a final separation happens through gravity.
