10 Essential Tips about Olive Oil:
1. How many different types of olive oil are available?
There are three principal types: Extra Virgin Olive Oil, Virgin Olive Oil and ordinary Olive Oil. The type is always indicated on the packaging. It is important to note that the quality of the oil in all these categories does not depend on the variety of olive from which it is made.
a. Extra Virgin Olive Oil: The highest category of olive oil is obtained directly from the olives, using solely mechanical processes (washing, milling, centrifugation or pressing, decantation and/or filtering). This type of olive oil has an excellent aroma and flavour and under 0.8% acidity (current legal requirement).
b. Virgin Olive Oil: Olive oil obtained directly from the olives, extracting the oil by mechanical processes (washing, milling, centrifugation or pressing, decantation and/or filtering). This type of olive oil has a pleasant aroma and flavour, and under 2% acidity (current legal requirement).
c. Olive Oil: Olive oil containing a mixture of refined olive oil and virgin olive oil. This grade of olive oil contains only oils that have been refined (which affects the aroma, colour and acidity content) and oil obtained directly from olives using mechanical processes (washing, milling, centrifugation or pressing, decantation and/or filtering). This oil has an acidity content of below 1% acidity (legal requirement).
2. How much does the flavour of Olive Oil vary?
Like wine, Extra Virgin olive oils vary considerably. Their colour and flavour depends on the type of olives from which they are made and external factors such as climate, altitude and soil type.
3. How many types of olive can you find?
In Spain alone, more than 260 varieties of olive are grown. The most important varieties include: Picual, Hojiblanca, Abequina, Cornicabra, Empeltre, Blanqueta, Manzanilla, Manzanilla Cacereña, Verdial, Carrasqueña, Lechín and Gordal.
4. What is the acidity content of Olive Oil?
The acidity is one of the chemical parameters of Olive Oil which indicates the level of free fatty acids in the oil (expressed in % of oleic acid). The acidity is a chemical parameter. It does not necessarily determine the quality of the olives nor does it have an effect on the flavour. Low acidity indicates that a virgin olive oil has been made using healthy olives, produced under optimum conditions throughout its production.
Extra Virgin Olive Oil – no more than 0.8 % acidity Virgin Olive Oil – no more than 2 % acidity
Olive Oil – no more than 1 % acidity
5. What is the best way to store Olive Oil?
Olive oil should be stored in a cool place, at 15-20oC, and out of direct sunlight.

These types of containers are used because they help to keep the oil in its best condition.
