How to become an olive oil taster: a guide to the profession

Olive oil taster: a look at the history, required skills, and future of the profession

When people think of tasting, their minds often go straight to wine or maybe craft beer. But those who truly know extra virgin olive oil are aware of a rich field of sensory experiences just as deep and fascinating — a complex universe of aromas, bitterness, spiciness, and countless vegetal nuances. This world is safeguarded, interpreted, and shared by a figure that is as technical as it is poetic: the olive oil taster.

In this article, I'll tell you about who olive tasters are, how to become one, what opportunities this evolving profession offers, and why it might become your next big passion.

An old tradition, a modern profession

Olive oil tasters aren't (just) romantic souls with a refined palate — they're trained professionals, certified through official courses, capable of assessing the strengths and flaws of an extra virgin olive oil with method and precision. Their judgment carries legal weight in official tasting panels (see Ministerial Decree of October 7, 2021), alongside chemical analyses.

Olive oil tasting has its roots in traditional Mediterranean farming culture, when a sip of oil fresh from the mill was enough to tell whether the product was good. But it wasn't until the 1980s that sensory analysis became a structured technical discipline, with the introduction of an official tasting method and the first European regulations.

What the law says

In Italy, formal recognition of the profession came with the decree on June 18, 1991, which established the importance of professional tasting in evaluating the quality of virgin and extra virgin olive oils. Today, olive oil tasters work in a variety of settings and are playing an increasingly bigger role in the growing world of olive oil tourism, where tasting becomes storytelling, an experience, and sensory education.

How to become an olive oil taster: 3 key steps

• Attend a technical course
• Take part in 20 certified tasting sessions
• Register with the National List of Olive Oil Technicians and Experts

1. Technical course and physiological aptitude for tasting

The first step is to attend a technical course for olive oil tasters, usually lasting around 35–40 hours, organized by entities such as ONAOO, OLEA, UMAO, APOL, or other accredited regional institutions. The program includes theory on olive cultivation, production processes, and the commercial characteristics of olive oil, sensory analysis based on the IOC (International Olive Council) method, and guided tastings of oils with both positive and defective attributes, as defined by EU Regulation 2568/1991. At the end of the course, you'll take both a practical and theoretical exam. If you pass, you'll receive a certificate of physiological aptitude for tasting — your first “license” as a fully recognized olive oil taster.

2. 20 certified tasting sessions (within 2 years)

After the course, it's time to train your senses. You'll need to take part in at least 20 certified tasting sessions within a recognized panel, under the guidance of a Panel Leader. Each session sharpens your ability to recognize aromas, defects, intensity, and balance.

3. Registration in the National Register

Once you've completed the required sessions, you can apply to join the National Register of Technicians and Experts of Virgin and Extra Virgin Olive Oils, maintained by MASAF. From that moment, you will be officially recognized as an olive oil taster.

What happens after that? Learning never stops (and neither does refining your palate)

Becoming an olive oil taster is not the final goal — it's just the beginning. To stay updated and continue improving, you can take advanced courses, enroll in master programs for professional tasters, pursue the title of Master Taster, and join countless opportunities for study, exchange, and guided tasting. Olive oil sensory analysis is a living art, rooted in sensitivity, precision, and openness. Every bottle tells a new story.

What does an olive oil taster do today?

Olive oil tasters don't just fill out sensory evaluation sheets. They're hybrid, versatile figures who can join quality-control panels for PDO and PGI certifications, work with farms and olive mills to improve production, teach courses, lead tastings, and take part in olive oil tourism events, and write, share knowledge, and communicate the world of olive oil in different forms. They combine analytical skills and storytelling, scientific rigor, and the ability to connect with people. They serve as a bridge between the land and the consumer, between the olive tree and the dining table.

Olive oil taster, deguster, and sommelier – what's the difference?

These terms are often used interchangeably, but they don't mean exactly the same thing: the olive oil taster is a formally recognized professional, listed in the National Register, whose evaluation carries official weight in tasting panels; the deguster, an informal taster, is usually linked to events or the restaurant industry and requires no certified technical training; the olive oil sommelier focuses on pairing olive oil with food, particularly in gastronomic settings, with a sensory and descriptive approach. All are important, but they have distinct roles and areas of expertise.

New perspectives – from taster to oleologist

Alongside the established role of the olive oil taster, a new profession is emerging: the oleologist. Oleologists are multidisciplinary experts who combine agronomic knowledge, sensory analysis, and communication skills — holistic olive oil consultants who can advise producers, organize experiences, and provide both technical and commercial storytelling. The future of olive oil will likely depend on this mix of expertise, skills, and the ability to both taste and communicate olive oil effectively. We might explore this further in a future article.

My journey between olive oil, passion, community and the land

In 2022, I attended a professional olive oil tasting course with APOL Scarl, and it was love at first scent. From that moment on, I started combining my background as a tour guide with my growing passion for olive oil culture. In 2023, I took a course on food-and-olive-oil pairing at EvooSchool in Rome, and in 2024, I joined the National Register of Certified Tasters. Tasting olive oil has become, for me, a way to see the region with new eyes — and a new palate. Olive oil is alive, and every drop tells the story of a landscape, a choice, a person.

Becoming an olive oil taster means training your senses, discovering the landscape inside a bottle, defending Italian quality, and perhaps even imagining a whole new career path.
