Olivar, por cien caminos,
tus olivitas irán
caminando a cien molinos.
Antonio Machado (1875-1939)

Nearly one third of the olive pulp is oil, so it has been easily extracted since ancient times.

Olive oil is a vegetable oil mainly for kitchen use. It is extracted from the freshly harvested fruit from the olive tree (Olea europaea) called olive or aceituna (in the Spanish language). Its name comes from the Arabic word “azzait” that means “olive juice”. Olive oil is nothing but the result of squeezing the ripe olive. This has always been quite easy since almost one third of the olive pulp is oil. Such extraction is made in plants called olive oil mills (almazaras in Spanish), according to COI standards to get the best quality.
