What is olive oil and what are its benefits?

Olive oil is an oily substance that has been around since 4,000 BC and is made from the fruit of the olive tree: olives.

Extra virgin, virgin, lampante or refined olive oil – what should you pay attention to?

Olive oil is a product that must be prepared with care in order to achieve a high quality result. This implies that there are many criteria to check when choosing an olive oil product. But the first one to define is the level of acidity you are looking for: virgin, extra virgin, lampante or refined.

In making this decision, consider primarily the use you will make of it. For cooking, more treated oils are preferred, as they accentuate flavours better. While cosmetic treatments can be effective with less treatment. The more the oil is treated, the lower the acidity level.

Buying criteria: factors that allow you to compare and rate different olive oil products

Before choosing an olive oil or an olive oil-based product, you should take into account some criteria to ensure the best decision. We tell you what these aspects are that you should consider.

  • Purity
  • Aroma and taste
  • Packaging
  • Date of production


The purity of olive oil is determined by various indicators, and as you might expect, the ideal is maximum purity. It is common for the oil to be contaminated on many occasions during the preparation process, but these cases are exceptions.

For the average user it is very difficult, if not impossible, to determine the purity level of an oil. So the best option is to trust the brand that offers the oil. Many culinary specialists recommend looking for small brands, as when preparing large quantities of the product it is more likely to be contaminated.

Also check that the brand you are considering does not use inappropriate chemicals to refine the oil. Mediterranean brands have more prestige than those from other regions, as this is the land that gave birth to this oil several millennia ago.

Aroma and flavour

These two are indicators of the quality of the product, as when it is poorly manufactured these are the aspects that suffer the most. So you can determine the quality of the oil you are going to buy by paying attention to these aspects.

Aroma. In theory an extra virgin oil should have a fresh and penetrating aroma, as well as a mild flavour and an absence of acidity. If it does not meet these characteristics it is not in the best condition, so it is preferable to look for another option.

Flavour. In this respect, acidity is the indicator of quality. More refined oils are less acidic and ideal for gastronomy, but if you are looking for an aesthetic treatment you can save a few pesos if you opt for a low refined oil.


Olive oil can be seriously damaged by a certain spectrum of light. Therefore, during its preparation, it should not be exposed to light, and it is often preferred to do so at night.

So it is important to avoid oils that are packaged in transparent packaging, as these are likely to have been affected. Those packaged in dark green or black bottles are protected, as are those packaged in cans.

Date of manufacture

The passage of time is something that does not favour olive oil, as it is one of those products that are at their best when fresh. Therefore, the best thing to do is to buy an oil whose date of manufacture is recent, as recent as possible.

Oils less than 1 year old. These are “young” oils, whose acidity level is low and whose flavour is at its best. If you need oil to cook delicious dishes you should look for this type of oil.

Oils older than 1 year. With time, olive oil loses many of its properties, so they are not recommended for gastronomic consumption. Use these oils for cosmetic treatments.
