When it comes to extra virgin olive oil, it's often thought that "one is as good as another." In reality, the difference between a quality oil and an industrial one can be enormous, both in taste and health benefits.
But how do you recognize a true quality extra virgin olive oil?
Labels are the first useful tool for navigating the different types of oil, starting with the fundamental distinction between virgin and extra virgin olive oil. Virgin olive oil is obtained exclusively through mechanical processes, without the use of chemical substances; however, to be classified as extra virgin, it must meet more stringent requirements. These include a free acidity not exceeding 0.8 g per 100 g of product and the absence of sensory defects highlighted by panel tests.
An authentic extra virgin olive oil is not only evaluated based on chemical parameters, but also through organoleptic tests, which verify the presence of positive notes—such as fruity, bitter, and pungent—and the absence of defects, such as rancid, mold, or metallic hints.
Certain legal statements must be included on an oil package:
SALES DENOMINATION: the wording "extra virgin olive oil" or "virgin olive oil" must be explicitly stated;
ORIGIN/PRODUCTION AREA: indicates the country or geographical area from which the olives used originate. You may find indications like "100% Italian" or "EU" or "non-EU." In the case of an Italian extra virgin olive oil, this formula can indicate not only that the olives were grown and harvested in Italy, but also that their processing took place within the national territory. Some producers choose to provide even more detailed information, also specifying the production area. This transparency helps reconstruct the product's history from olive grove to bottling, protecting the consumer and helping to strengthen trust in the producer;
NET QUANTITY: i.e., the content of the package expressed in liters or milliliters;
MINIMUM DURABILITY DATE (TMC): the date by which the oil retains its characteristics, if stored correctly. In fact, even a "good oil" can become rancid or lose some of its organoleptic characteristics, for example, if exposed to direct light or excessively high temperatures;
PRODUCER'S NAME/COMPANY NAME: to indicate who markets the product.
It is advisable to be wary of excessively low prices, especially when the information provided is incomplete or there is no reference to the country of origin of the raw material.
Naturally, the label cannot replace the direct experience of tasting, but it is still an excellent starting point for making an informed choice.
From a sensory perspective, a good extra virgin olive oil can be recognized by its aroma, with fruity notes of fresh olive, often accompanied by herbaceous hints. On the palate, it is normal to perceive a slight bitterness and a pungent sensation: characteristics linked to the presence of polyphenols, beneficial natural substances.
