Extra Virgin Olive Oil and Taste: Myth, Fact and Sensory Profile

Myth – The presence of a bitter and/or spicy taste in olive oil is a defect

Many people mistakenly believe that a bitter taste on the tongue or a peppery sensation in the throat are signs of poor-quality olive oil. This misconception has been passed down from generation to generation, leading people to seek only sweet and mild flavors. As a result, some people even reject excellent olive oils simply because they do not meet this false expectation.

The Fact – Bitterness and Spiciness Signal Quality in Olive Oil

The truth is just the opposite. These characteristics are key indicators of a high-quality extra virgin olive oil. The bitterness and pungency reveal the presence of natural antioxidants and polyphenols, compounds that reflect freshness and health benefits. Rather than being flaws, they are signs of vitality and proof that the oil was crafted from carefully selected, early-harvest olives at their peak.

The Role of Phenolic Compounds

The reason lies in phenolic compounds, powerful natural antioxidants found in freshly olive fruits. These compounds are responsible for the distinct bitterness and spiciness that define a premium extra virgin olive oil. Phenols not only protect the olive oil itself from oxidation, extending its shelf life, but also provide significant health benefits, such as anti-inflammatory and cardioprotective properties.

Understanding the Sensory Profile of Olive Oil

Professional tasters evaluate olive oil based on its organoleptic (sensory) characteristics, organoleptic evaluation is based on three pillars:

• Fruity: It involves all olfactory sensations. It derives from healthy, fresh olive fruits and it is the first thing we can directly perceive through the nose. It is the most important characteristic in the evaluation process because if it is not detected, an olive oil cannot be classified as extra virgin or virgin.
• Bitter: Characteristic primary taste of olive oil obtained from green olives or olives turning colour. It results from the action of phenolic substances (mainly oleacine) and we can perceive it, depending on its intensity, through the entrapped tasting nipples on the V region of the tongue.
• Pungent: Biting tactile sensation characteristic of early harvest olive oils deriving from olives that are still unripe. It results from the action of certain phenolic substances (mainly oleochantal), can be perceived in the entire oral cavity, starting with the pharynx, and gradually disappears after tasting.

The stronger the bitterness and pungency, the higher the concentration of these beneficial compounds, a reliable marker of premium extra virgin olive oil. Detecting the intensity of the two characteristics in combination with the detection of the fruity aroma, constitute the sensory evaluation of an olive oil.

Therefore, sensory evaluation locates and describes the positive or negative characteristics of an olive oil using the senses of smell and taste from a specialized tasting panel. It is a necessary qualitative criterion for the classification of an olive oil in the categories of extra virgin, virgin or lampante, depending on its organoleptic characteristics. It is equivalent to the other quality parameters and irreplaceable!

Why Bitterness and Pungency Are Positive Signs

As mentioned previously, fruity, bitter and pungent are the positive characteristics of an olive oil. On the other hand, the most common defects we encounter are rancidity, fusty, musty and muddy which are among others the negative characteristics of olive oil. Therefore, lower quality olive oil may exhibit a common defect known as ‘rancidity’, which is caused when olive oil undergoes intense oxidation. The rancid odor releases an unpleasant smell of fried oil. Other defects may include “winey-vinegary,” which is reminiscent of poor-quality wine or vinegar, or moldy, which has a corresponding taste, or even fusty and muddy. As the intensely bitter and spicy flavor may surprise consumers who are accustomed to sweeter and milder olive oils, it is recommended to use high quality olive oil in cooking, mainly because of its increased nutritional value but also because of the objectively larger amount used in the preparation of a dish compared to the amount used, for example, in a salad. Consequently, while eating, you cannot perceive the intensity of bitter and pungent flavors. These characteristics are neutralized, allowing the consumer to absorb all the nutrients in large quantities.

So the next time you experience a pleasant bitterness or feel that peppery tickle in your throat, recognize it as a hallmark of high phenolic Extra Virgin Olive Oil, a product that is both delicious and nourishing.

The Kitchen Experiment You Should Try

You don’t have to be an expert taster to recognize quality. Try this simple home experiment:

• Boil a potato and cut it in half.
• Drizzle each half with a different olive oil variety or different type of olive oil.
• Taste and observe.

Notice how the aroma and flavor change dramatically. A defective olive oil will leave a flat or unpleasant taste, while a true extra virgin will enhance the potato with natural fruitiness, bitterness and spiciness.

Olive Epitome: Where Quality Meets Excellence

At Olive Epitome, we embrace excellence. Our extra virgin olive oil collection are produced in a way that preserves their natural phenolic compounds, offering authentic flavor and significant health benefits in every drop.

Conclusion – The presence of a bitter and/or spicy taste in olive oil is not a defect.

The sense of a bitter taste in the mouth and/or a spicy taste in the throat are factors of a superior quality olive oil. The intensity of bitter and spicy taste determines the content of phenols in olive oil, a valuable component due to its antioxidant effect in the human body.

We therefore seek to educate the consumer on how to choose a superior quality olive oil, which necessarily implies a bitter and spicy flavor.
