LET’S BREAK DOWN THE BASICS
How is Olive Oil Formed?
Olive oil is a liquid extremely beneficial fat, extracted from olives, the fruit of the Olea europaea tree.
To produce olive oil, ripe olives are harvested and then crushed into a paste.
This paste is mixed with water and subjected to a mechanical pressing process known as cold pressing.
This traditional method minimizes the use of heat, preserving the oil's delicate flavor profile and nutritional content.
The resulting mixture separates into three layers consisting of oil, water, and solid matter. The oil, being less dense than water, rises to the surface and is carefully extracted.
