What is olive oil?
Olive oil is a liquid obtained from olives and it is produced by pressing whole olives.
It is commonly used in cooking, whether for frying or as a salad dressing. Also, it used in cosmetics, pharmaceuticals, and soaps, and as a fuel for traditional oil lamps, and has additional uses in some religions. There is limited evidence of its possible health benefits. The olive is one of three core food plants in Mediterranean cuisine; the other two are wheat and grapes. Olive trees have been grown around the Mediterranean since the 8th millennium BC.
How is the olive oil produced?
It is produced by grinding olives and extracting the oil by mechanical or chemical processes. Green olives usually produce more bitter oil, and overripe olives can produce oil that is rancid, so for good extra virgin olive oil care is taken to make sure the olives are perfectly ripened.
Extra virgin olive oil
Extra virgin type is the top grade of olive oil, delivering the best taste and the full health benefits of the oil. The olives are crushed at a mill and the oil is extracted via mechanical means – versus refined type extracted through the use of heat or chemicals.
First cold press olive oil
This outdated term is actually used mainly for marketing purposes. It’s not a required standard. It really just means the oil underwent one phase of “separation” from the olives at the mill – versus repeated separations – and no heat was involved in extracting the oil from the olives.
Pure olive oil / olive oil
Light olive oil
Though it’s made to sound as if it is, “light” olive oil is not a diet product. It’s basically the same as “pure” olive oil. It’s really light in flavour or colour – not calories or fat. In short, the term “light” has absolutely nothing to do with the quality or health benefits of the oil.
Pomace olive oil
Oil extracted from the olive pomace – the solid waste left over from the milling process. It includes olive pits, skin and flesh. The oil is made by re-milling the pomace to extract the remaining 1–5% of oil that’s left in the waste. It also can be obtained by mixing solvents into the pomace; heat is then used to extract additional oil from the pomace.
Environmental impact of olive oil production:
Cold-pressed or cold extraction means “that the oil was not heated over a certain temperature (usually 27 °C (80 °F)) during processing, thus retaining more nutrients and undergoing less degradation.

How to taste an extra virgin olive oil?
The tasting of olive oil is the same as the wine tasting. The best way of tasting it is to pour 1-2 tablespoons of oil into a wineglass. Then hold the glass in one hand and cover the top of the glass with the second one. This way you will keep all the aromas inside of the glass. Hold it for 1-2 minutes until the oil warms up a bit and releases its full potential.
Then gently swirl the glass, take away the hand from the top and take a good sniff. After a few moments, you will start to notice the first smells. Among the main aromas of ripe or green olives, you may smell e.g. fresh-cut grass, cinnamon or tropical fruits.
Now take a good sip of the olive oil.
