Olive oil is extracted from olives, the fruit of the olive tree which, together with wheat and vines, makes up the triad of Mediterranean plants.

The composition of olive oil

The composition of this fruit varies, depending on the type of olive, the soil, the climate and how it is grown. Olives are composed of up to 32% oil, water and up to 35% formed by the stone and vegetable matter. All olives can produce excellent virgin oils, each with their particular characteristics. For this purpose the olives need to be healthy, they need to be picked carefully and they must be processed the same day they are harvested. The characteristics defining the qualities of virgin oils, such as their fragrance, freshness, sweetness, almondy taste, taste of apples, herbs, etc. reveal the diversity of types of olives. All those involved in growing and producing olive oil have an ultimate effect on the parameters affecting its taste and smell. Olive oil has exceptional properties for human health and its consumption is essential in most of the culinary creations made nowadays in Mediterranean countries.
