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. Most commonly the olives are crushed and the water is separated from the olive oil via centrifuge. Think of it as freshly pressed fruit juice. (Yes, olives are a fruit!)

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This outdated term is actually used mainly for marketing purposes.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

Oil that’s been refined to remove any defects, and with it, is stripped of the health benefits that extra virgin type is known for. It’s typically blended with just enough extra virgin olive oil to add flavour.

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. 

How to taste extra virgin olive oil

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. The best is to cover your whole mouth and tongue so you can taste all the impressions. Slurp the liquid and get some air into your mouth. Close your mouth and breath out through your nose. Thanks to this step you will be able to feel a whole bunch of other flavor notes. Now swallow some or all of the olive oil. The swallowing is very important and you may taste some pungency in your throat. Pungency is a positive characteristic of olive oil and it is a chemical reaction like the hotness of chilies. It can be very mild or so intense that it will make you cough.

The third of the three main attributes of olive oil, in addition to fruity and pungent, is bitter. Bitterness, like pungency, is also an acquired taste. As anyone who has ever tasted an olive right off the tree can attest, bitter is a prominent taste in fresh olives.

Which olive oil is for what type of cooking?

The extra-virgin olive oilhas full-bodied flavour. It can be used for all forms of savourycooking, including sautéing, stir-frying, roasting and marinating, and is the best choice for bread dipping and salad dressing. 

The pure olive oil or olive oil it’s typically milder than extra-virgin and more yellow in color. While not quite as high-quality as extra-virgin, it’s great for savourycooking and adds flavourand depth to a dish.

How to choose the best olive oil?

Always choose dark bottle – olive oil is very sensitive to light and heat and the dark glass prevents oxidation of the oil and protects the nutrition levels.

Select virgin or extra virgin olive oils – the EXTRA virgin oil is from the first press and has the highest grade. Also, it contains the most nutrients. As a second option choose regular virgin oil which is the next grade down. 

Origin of the olive oil– you should always pick an olive oil which is produced in a single country. 

Cold pressed– this means that the olive oil was produced without usage of any heat.

Pressing date– a good extra virgin olive oil should always have the “pressing date” so you know when it was produced.-

The 1-month rule– the olive oil does not age well, therefore you should only buy the amount which you will consume within 1 month. 

Avoid using clear glass and plastic bottles– due to the light and heat sensitivity the oils may oxidize in the bottle, thus produce more free radicals in your body.
