Botanically, an olive is approximately 60–70% water at harvest, with the remaining 30–40% comprising solids. The moment of harvest—whether the olive is picked early for a greener, more bitter oil or allowed to ripen for a milder, fruitier oil—dramatically alters the chemistry.

Traditionally, this involves crushing the olives into a paste. Virgin: A Chemical Divide.
The olive itself is a drupe, containing a fleshy exterior surrounding a hard stone. The fat content in the fruit typically ranges from 1% to over 30%, depending on the specific cultivar and ripeness, directly influencing the volume and character of the oil produced.

The critical step is separation; the oil must be separated from the solid pomace, which includes the skins, seeds, and pulp, and from the water content. Modern methods utilize malaxers, which gently churn the paste to encourage tiny oil droplets to merge into larger ones.
