PROFILO:

I began my journey with O.N.A.O.O. in 2022 as an enthusiast, driven by a desire to better understand olive oil. I attended the Official Technical Course without specific goals, but with great curiosity and a strong willingness to learn. I chose O.N.A.O.O. for its excellent reputation, international scope, and focus on professional training.

In April 2025, after completing the two-year Advanced Course, I became a certified Professional Olive Oil Taster. The program provided me with a clear method to taste and confidently identify both the positive attributes and defects of olive oil. Moreover, I consider knowledge and experience crucial in evaluating and selecting the right oil, and in being able to explain it effectively to others.

I also greatly value the international community that has formed — being able to learn from and interact with producers, importers, chefs, tasters, educators, and enthusiasts from around the world. This experience has motivated me to share more, organize tastings, and invite others to discover the richness of olive oil.

Currently, I am the founder of OLIIV, a company specializing in the import, sale, and promotion of high-quality extra virgin olive oil in Estonia. My goal is to spread knowledge and appreciation of quality olive oil, creating opportunities for discovery and sharing through tastings and cultural events.

This commitment stems from a passion cultivated over time: in the early 2000s, while studying Italian language and culture at the University for Foreigners of Perugia, I had the fortune to taste freshly pressed olive oil during the harvest in Umbria — a powerful and unforgettable experience.

Upon returning to Estonia, I began working in the food distribution sector, promoting Italian products for restaurants and major distributors. In 2008, I co-organized the first olive oil tasting event in Estonia, where I discovered the role of the professional taster — an idea that has since accompanied me throughout my journey.

Over the years, I have attended fairs such as Cibus, TuttoFood, Olio Capitale, and Sol&Agrifood. I have met producers in Italy and Spain, broadening my knowledge and deepening my respect for the dedication and passion involved in producing high-quality olive oils.

Manuela Guatelli

Manuela was born in Genoa but spent her entire childhood in Imperia. She currently resides between Imperia, Shanghai, and Bangkok.

She represents the fourth generation of can makers and is actively involved in the “Guatelli Museum”, which houses the Family Collection of Italian Olive Oil Cans. This collection comprises over 6,000 pieces of olive oil cans and lithographic stones, which provide important evidence of the flourishing industry related to the oil trade that developed in the late nineteenth and early twentieth centuries.

In 2006, Manuela relocated to Asia with her husband and four sons. Despite the distance, she has not forgotten her roots. She has promoted the prestige of extra virgin olive oil, the history and flavors of Mediterranean cuisine beyond national borders through organizing Italian cooking classes, on-demand chefs and catering.

Her passion for extra virgin olive oil has its roots in her family; in fact, her father dedicated his life to the production of oil cans. My father, who crossed Europe every week to sell his cans, would return home on weekends with stories and anecdotes about this fascinating industry.

Having a global vision of the oil market, he could grasp even the smallest nuances of it, which made me want to be part of this wonderful world. In recent years, she finally managed to crown her passion by attending the ONAOO Course and becoming a Professional Taster in 2024. Manuela is actively engaged with several Italian associations abroad, promoting the history, culture, and art of extra virgin olive oil tasting on a global scale.

Tevruz Feyza

Olive oil producer

She began her ONAOO courses in March 2023. She completed technical, advanced, and tasting courses, earning the title of ‘Assaggiatore Professionista ONAOO’ in November 2025. Throughout this process, she was able to learn about different cultivars, which are not easy to access, experience the oil tasting procedure, and witness its contribution to high-quality olive oil production and healthy olive oil consumption. She believes that continuing the activities and tasting sessions at ONAOO will have a priceless contribution to her work as an olive oil producer.

Wen Ling Ellen Wu

Ellen Wu is a Professional Taster of ONAOO since 2013. She imports olive oil in Taiwan. She handles marketing and education in her company.

She teaches olive oil tasting classes to chefs, salespeople, consumers, teachers, and students.

She wants to educate people and consumers about different olive oil products. She must also teach Taiwanese people about the nutrition and health benefits of extra virgin olive oil, and help them understand different types of olive oils based on their taste.

Alia El Askalany

Alia has added a new skill to her culinary & gastronomy portfolio, being the first Egyptian female chef to hold a certificate as an advanced professional olive oil taster & sommelier from ONAOO Scuola in Liguria, Italy (The National Organization of Olive Oil Tasters).

Through her tasting skills & extensive practice, Alia has started a wave of awareness & tasting events across Cairo by partnering up with premium Egyptian olive oil brands as well as taking it internationally via harvest retreats/gastro-tourism across the Mediterranean.

Guests, chefs & enthusiasts are invited to explore the world of extra virgin olive oil by understanding the harvest process, touring olive groves, doing professional tasting sessions to look out for flavor notes & positive attributes of the different oil varieties and taste and pair each variety with different dishes through her curated menus.

I am very looking forward to continuing my educational journey into the world of olive oil with ONAOO and its network of tasters and professionals in the field, and also look forward to also educating more clients through my work.

Through my company Oliiv, I import, introduce, and sell high-quality extra virgin olive oil in Estonia, primarily through an online store and curated experiences. The website and e-shop provide the opportunity to learn more about each product and make informed purchases.

My activities include guided tastings, culinary pairings, and cultural events — from intimate gatherings at home to market events and musical evenings with olive-oil-based cocktails. The goal is always to spark curiosity and offer enjoyable and educational experiences centered on olive oil.

In a country where butter dominates the cuisine, there is great potential to show how olive oil can be part of a healthy, joyful Mediterranean lifestyle. For this reason, collaboration with chefs and cooking schools is becoming an important part of my work.

Looking ahead, I am particularly interested in engaging with the international olive oil community. Participating in global competitions — both as a taster and as a judge — is one of my aspirations. It is a valuable way to continue learning, contribute to quality standards, and bring new ideas and energy to the Estonian market.

We venture into the culinary world not just for taste, but also for culture. It means experiencing a moment of insight, a flash of memory, or understanding a tradition, a civilization. — Umberto Eco
