Extra Virgin Olive Oil Tasting

Extra virgin olive oil is the natural juice of the olive, produced exclusively by mechanical means and without any chemical treatment. Its quality is shaped by many factors, including the olive variety, microclimate, soil, harvest time, fruit health, prompt milling and proper storage conditions.

Sensory evaluation is the internationally recognised method used to assess the quality of extra virgin olive oil. Through smell, taste and retronasal perception, we evaluate its freshness, purity, balance and character without being influenced by its colour.

Extra virgin olive oil tasting is one of the most authentic gastronomic experiences in Crete, connecting Cretan olive oil, the Mediterranean diet, local production and genuine Cretan hospitality.

At Douloufakis Winery, extra virgin olive oil tasting is a natural continuation of the introduction to Cretan gastronomy, the Mediterranean diet and the authentic Cretan way of life. Through this experience, visitors discover Cretan extra virgin olive oil, learn the basic principles of sensory evaluation and connect with one of the most important treasures of the Cretan land and local agri-food tradition.

The Three Characteristics That Define the Quality of Extra Virgin Olive Oil

Fruitiness is the most important positive sensory attribute of extra virgin olive oil. It describes the full range of aromas that come from healthy, fresh olives, whether green or ripe, and expresses the unique identity of the variety. It is perceived both through direct smelling and through retronasal perception.

Bitterness is a natural and desirable characteristic of extra virgin olive oil. It is most commonly associated with oils produced from green or early-harvest olives and is caused by naturally occurring polyphenols such as oleacein and oleuropein derivatives. It is mainly perceived at the back of the tongue and, when balanced with the oil’s other characteristics, is an indication of freshness and quality.

Pungency is the distinctive peppery or lightly burning sensation that appears mainly in the throat during tasting. It is particularly typical of fresh, early-harvest olive oils and is associated with natural phenolic compounds such as oleocanthal. It is a positive sensory attribute and a sign of high quality when it is harmoniously balanced with fruitiness and bitterness.

The Five Steps of Extra Virgin Olive Oil Tasting

Professional extra virgin olive oil tasting can be organised into five practical steps: preparation, warming the sample, olfactory evaluation, tasting and retronasal evaluation using the strippaggio technique.

1. Prepare — Choose the Right Glass

Proper tasting begins with the right environment. The room should be free from strong odours, perfumes and smoke so that the sense of smell is not affected.

The morning is considered the ideal time for professional tasting because olfactory and gustatory sensitivity are usually higher before meals. For this reason, tasting sessions are often held between 10:00 and 12:00. Before tasting, avoid coffee, smoking, strong perfumes, scented cosmetics and intense flavours. The taster should be calm, focused and have a neutral palate.

Use a small dark-coloured or opaque glass so that the colour of the olive oil does not influence your judgement. In professional tastings, special blue or red glasses are used because colour is not considered a reliable indicator of quality.

2. Warm — Warm and Aerate the Sample

Pour approximately 14–16 ml of extra virgin olive oil into the glass. Hold the glass in the palm of your hand and cover it so that the aromas can concentrate.

Gently warm the sample for approximately 30 to 60 seconds. Mild warming helps release volatile aromatic compounds and allows a clearer evaluation of the olive oil’s fruity character.

3. Smell — Evaluate the Aromas

Remove your hand or the cover from the glass and inhale deeply. A high-quality extra virgin olive oil should express freshness, vitality and the aroma of healthy olive fruit.

Early-harvest olive oils tend to display greener and more herbal aromas, greater bitterness and a more intense pungent sensation. Oils made from riper olives may have a softer, sweeter and more mature aromatic profile.

4. Taste — Taste the Extra Virgin Olive Oil

Take a small amount of extra virgin olive oil and allow it to coat the entire mouth, including the tongue, palate and inner cheeks. At this stage, evaluate bitterness, pungency, texture, balance and the length of the finish.

• Bitterness: perceived mainly towards the back of the tongue and often associated with a higher concentration of polyphenols.
• Pungency: expressed as a peppery sensation or a light burning feeling in the throat.
• Softness: reflects the roundness and texture of the olive oil in the mouth.
• Balance: describes the harmonious relationship between fruitiness, bitterness and pungency.

5. Strippaggio — Retronasal Evaluation

The strippaggio technique is an essential tool in professional olive oil tasting. While the oil remains in the mouth, draw small amounts of air through the teeth.

This action emulsifies the sample and carries volatile aromatic compounds towards the retronasal cavity. It allows the taster to perceive the olive oil’s aromatic complexity, purity and persistence more clearly.

What Defines a High-Quality Extra Virgin Olive Oil?

A high-quality extra virgin olive oil is distinguished by clean fruitiness, the absence of sensory defects and a harmonious balance among its three positive sensory attributes: fruitiness, bitterness and pungency.

An extra virgin olive oil may be delicate and mild, medium or intense. In every case, quality is judged by aromatic purity, balance, the length of the finish and the faithful expression of the olive variety and fruit.

Common Defects in Olive Oil

Sensory evaluation does not focus only on positive characteristics. It also helps identify defects that may result from poor fruit storage, delayed milling, fermentation or oxidation. The presence of even one of the following defects prevents an olive oil from being classified as extra virgin.

• Rancid: reminiscent of old oil, wax, paint or stale nuts. This defect develops when olive oil undergoes significant oxidation due to age or exposure to light, air or high temperatures.
• Mouldy or damp: reminiscent of humidity, mouldy olives or enclosed, damp spaces. It originates from olives stored in humid conditions, where moulds and yeasts develop, or from fruit collected with soil and mud that was not properly cleaned before milling.
• Winey or vinegary: reminiscent of wine or vinegar and associated with undesirable fermentation. It results from unwanted fermentation of the fruit or olive paste, which leads to the formation of compounds such as acetic acid, ethanol and ethyl acetate.
• Fusty or muddy sediment: an anaerobic fermentation defect that may evoke stable-like or swampy sensations. It develops when olives remain piled or stored for too long before milling, allowing anaerobic fermentation to occur. It may also develop when olive oil remains in prolonged contact with sediment at the bottom of storage tanks.
• Wet wood: reminiscent of damp wood, wet cardboard or moist timber and accompanied by a loss of freshness and fruitiness. This defect may occur in oils made from olives affected by frost.

The Role of Harvest Time

Harvest time has a major influence on the character of extra virgin olive oil. Early-harvest oils often display a greener, more bitter and more pungent profile, with a stronger sense of freshness and intensity.

Oils produced from riper olives may show softer, rounder and more mature aromatic characteristics. For a professional taster, neither style is inherently superior. Quality is judged by purity, balance and the absence of defects.

A Practical Exercise for Beginners

For beginners, a useful exercise is to taste extra virgin olive oil on a warm boiled potato, bread or rice. Heat helps release aromatic compounds and makes fruitiness easier to recognise.

Real progress, however, comes through repetition, comparison between different olive oils and the development of sensory memory.

The Correct Tasting Temperature

Olive oil that is too cold has a reduced aromatic expression and makes fruitiness more difficult to perceive. Excessive warming, on the other hand, may alter the natural aromas and affect the balance of the sample.

For this reason, professional olive oil tastings are carried out at approximately 28°C, a temperature considered suitable for revealing volatile aromatic compounds.

Common Mistakes Made by Beginners

• Judging quality exclusively by the colour of the olive oil.
• Tasting olive oil only with food, without first evaluating it on its own.
• Ignoring aroma and focusing exclusively on taste.
• Tasting too many oils without cleansing the palate with water or neutral foods.
• Mistaking bitterness and pungency for defects, even though they are positive characteristics of fresh extra virgin olive oil.
