We all know how healthy olive oil is; it’s rich in monounsaturated fatty acids, which increases life expectancy by lowering the risk of heart disease, high blood pressure, and stroke. It’s also known to fight osteoporosis, prevent skin cancer and help with depression. Its many benefits do not mean that olive oil is always of the best value; in fact, the majority of olive oils on the market are not good quality. Keep reading to ensure you get the best for your next bottle.
How Olive Oil is Made
Olives are picked, pressed and separated in a meticulous process. It is important that when the olives are picked off of the trees, they are stored in shallow containers so as not to crush each other. Crushing can lead to oxidation and fermentation, which produce a bitter taste.
In the process of pressing, large stainless tell rollers grind the olives into a paste, which is then stirred with water in a process called malaxation, which allows the oil molecules to concentrate.
A process of stirring occurs for up to 40 minutes, and then the paste is placed in a centrifuge. Inside the centrifuge, the pulp is spun at high speeds to separate the oil and water from the solid material.
The oil is then stored in a stainless steel container at 65 degrees Fahrenheit before it is bottled and shipped off.
Good Qualities
Here are some signs you’ve selected a high-quality bottle of olive oil.
Pungent
This is a kick you should feel for a brief moment on your throat, which is another sign of freshness and also an indication that there are antioxidants present in the oil. However, this small sting on your throat should not linger.
Fruity
Since olives are a fruit, after all, your olive oil should have a degree of fruity flavor, whether the olives are ripe or unripe. The overpowering taste should be fresh instead of heavy.
Bitter
Believe it or not, bitterness is a good thing in olive oil, because it means the fruit is crisp and fresh. Many find this to be off-putting, but a less bitter taste could be a sign of age.
Bad Qualities
If you taste any of these flavors in your olive oil, it could be a sign you’ve bought a poor quality brand.
Metallic
The presence of this taste could mean the oil had prolonged contact with metal containers or tools.
Moldy
This musty flavor could mean the oil was stored at incorrect temperature for an extended period, a place where fungi and bacteria could have grown.
Vinegary
This will show the olives have fermented. The oil should not smell or taste like wine would, oxidation is a process that allows for fermentation.
Rancid
Olive oil, like any fatty compound, has a shelf life. The smell of rotting meat and the taste of old nuts are redolent of what bad olive oil could taste like.
Other tests
Check the label to ensure it is certified 100% extra virgin olive oil, and a quick search on Google when dealing with big corporate brands will usually lead you a quick answer.
Extra-virgin olive oil is comprised of mostly monounsaturated fats which solidify when cold. So, if you put real extra-virgin olive oil in the fridge, it will become thick and cloudy, and high-wax varieties of olive oil will even solidify completely. Artisan and locally-produced olive oils have always passed every scientific test of authenticity. We recommend you buy your olive oil locally.
