Olive oil extraction is the process of extracting the oil present in olive drupes, known as olive oil.
 Olive oil is produced in the mesocarp cells, and stored in a particular type of vacuole called a lipo vacuole, i.e., every cell contains a tiny olive oil droplet.
 Olive oil extraction is the process of separating the oil from the other fruit contents (vegetative extract liquid and solid material).
 It is possible to attain this separation by physical means alone, i.e., oil and water do not mix, so they are relatively easy to separate.
 This contrasts with other oils that are extracted with chemical solvents, generally hexane.
 The first operation when extracting olive oil is washing the olives, to reduce the presence of contaminants, especially soil which can create a particular flavor defect called "soil taste".

Panathenaic amphorae were the amphorae, large ceramic vessels, that contained the olive oil given as prizes in the Panathenaic Games.
 Some were ten gallons and 60-70 cm high.
 This oil came from the sacred grove of Athena at Akademia.
 The amphorae which held it had the distinctive form of tight handles, narrow neck and feet, and they were decorated with consistent symbols, in a standard form using the black figure technique, and continued to be so, long after the black figure style had fallen out of fashion.
 Some Panathenaic amphorae depicted Athena Promachos, goddess of war, advancing between columns brandishing a spear and wearing the "aegis", and next to her the inscription τον αθενεθεν αθλον ""(one) of the prizes from Athens"".
 On the back of the vase was a representation of the event for which it was an award.
 Sometimes roosters are depicted perched on top of the columns.
 The significance of the roosters remains a mystery.
 Later amphorae also had that year's archon's name written on it making finds of those vases archaeologically important.
