The Difference Between Extra Virgin Olive Oil and Other Olive Oil Varieties
We all know that when it comes to olive oil, you have a choice between regular olive oil and extra virgin olive oil. But how do they differ? Olive oil is olive oil, right? Hate to break it to you, but they’re not the same. Both oils are extracted from the fruit of an olive tree, yes, but how much do they really vary? Well, we’re here to tell you the difference.
The Basics of Extra Virgin Olive Oil
Temperature and Extraction
So, olive oil is what we get from olives. That’s pretty straightforward. However, it’s the process of extraction that differs the two. The thing to remember about extra virgin olive oil is that it’s an unrefined oil and is the highest-quality olive oil available. There are very specific standards oil has to meet to receive the label ‘extra-virgin’. These standards include cold-extraction, where the milling temperature is kept below 30 ºC, so as to retain delicate flavours, antioxidants and vitamins, as well as no additives or preservatives.
Owing to the way extra-virgin is made, it retains a much more pronounced olive taste and has a lower level of oleic acid than other olive oil varieties. It also contains more of the natural vitamins and minerals found in olives.
In short, extra virgin olive oil is considered an unrefined oil since it’s not treated with chemicals and, because it’s produced via cold-extraction, it’s not altered by temperature.
Low levels of oleic acid
What determines a great extra virgin is the low level of oleic acid (the fatty acid that occurs in commercial vegetable oil) and the absence of flaws in the colour, taste and smell. It typically has a golden-green colour, with a distinct olive, fruity flavour and a light peppery finish.
Cooking with Extra Virgin Olive Oil
Contrary to popular belief, you can cook with extra virgin olive oil. A newer mindset tells us that it does have a higher smoke point than originally thought and can be successfully used for frying. It is, in fact, extremely versatile for cooking and can be used for many different applications. See a selection of recipes here.
Olive Oil and Other Oil Types
Now that we know what extra virgin olive oil is, what does that mean for the rest of the olive oils out there? Extra virgin olive oil is what comes of the first pressing and those labelled ‘virgin olive oil’ or just ‘olive oil’ will come from the second pressing and so on. Naturally, the oil derived from pressings beyond the first one will have lower levels of minerals and nutrients.
Basically, regular olive oil is a refined version of its extra virgin olive oil cousin and will often have been blended with other plain and possibly lower quality oils (hence it may be cheaper). It will have a much more neutral (much less olivey) taste. You can use it any way you would use extra virgin olive oil, provided you aren’t after that high-quality and pronounced flavour.
Olive Pomace Oil
The last kind, after all this pressing, is not technically called olive oil at all – it’s called olive pomace oil. This is made when the solid residue from previous pressings (the pomace) is chemically dissolved and turned into oil, it has very little olive notes and tastes quite neutral. It will have very little or almost none of the nutrients and antioxidants found in extra virgin olive oil. Some countries have actually gone as far as banning the sale of olive pomace oil.
Why you should buy the real deal
- You may pay a little more but you’re getting all the benefits and antioxidants.
- The flavour is far superior.
- Many European governments subsidise olive oil production, so prices on imported olive oils may be lower. However, if you buy local rather than imported, you are supporting our farmers, our economy and job creation – and that makes it really worth the few extra Rands. Support local!
In summary, your best bet, if you want the real deal with all the goodness and benefits, is to look for local, cold pressed/extracted extra virgin olive oil. We have an incredible choice of locally produced oils that fit this bill and you’ll find many in the 3 categories of delicate, medium and intense, which suit different styles of cooking. The best option is to try a few in each style to find the one that best suits your palate.
