Differences in olive oil and extra virgin olive oil – taste, quality and production

Olive oil is a versatile and healthy ingredient that can be used in a variety of dishes, but with so many different types of olive oil available, it can be confusing to know which one to choose

Olive oil is a kitchen essential across the globe, renowned for its health benefits, culinary versatility, and deep roots in Mediterranean tradition. It has numerous applications — from being used in vinaigrettes, marinades, and dishes featuring vegetables and meats, to desserts and baked goods.

This nutritious fat is a plant-based oil produced by pressing or crushing fresh olives.

Yet, with supermarket aisles brimming with countless bottles and tins, it can be difficult to work out which olive oil to select. And that’s before tackling the vital question: what sets olive oil apart from “extra virgin” olive oil?

Are olive oil and extra virgin olive oil the same?

Put simply, no. While both originate from the humble olive, the distinctions lie in the production techniques, flavour, growing regions, and overall quality, reports the Express.

Extra virgin olive oil is the finest-quality olive oil available. It is an unrefined oil, which means it is created by cold-pressing whole olives without any extra heat or chemicals.

This method preserves the purest flavours and aromas, capturing the true character of the olive.

Extra virgin olive oil is completely free from defects, has an acidity level of less than or equal to 0.8%, and, when stored properly, boasts exceptional taste and aroma.

The flavour of your extra-virgin olive oil will vary depending on the variety of olive. It can span from buttery and herbal to peppery and bitter.

Conversely, regular olive oil is a lower-grade product composed primarily of refined olive oil. Occasionally, producers will process the olive paste through the mill several times to extract additional oil, which reduces the quality of the end product.

As regular olive oil doesn’t need to meet stringent manufacturing or taste requirements, it is considerably more economical than extra virgin olive oil.

On the whole, regular olive oil possesses a more neutral flavour profile compared to extra-virgin olive oil. It is also typically paler in colour and aroma.

While extra-virgin olive oil is superior in quality to regular olive oil, there’s room for both varieties in your kitchen.

Can different oils be substituted for each other?

Put simply, yes. If a recipe calls for olive oil, which many recipes do, you can choose either extra-virgin or regular olive oil.

The decision is yours and largely comes down to personal preference. Both varieties of olive oil work well for baking and cooking, though bear in mind they have different smoke points.

As a general rule, it is advisable to use the more flavourful extra-virgin olive oil for dipping bread, in dressings, dips, and raw dishes, as well as for final flourishes, enabling the flavour to truly shine through.
