Desiree Ditterich

I am an agricultural entrepreneur and, since 2003, I have been cultivating an olive grove in the Maremma region, between Tuscany and Lazio, using exclusively natural and organic farming methods.

In 2016, together with my niece, I turned this passion into a professional business by developing both olive oil production in Italy and its distribution through a company based in Germany. In addition to organic extra virgin olive oil, we also produce a line of organic cosmetics made from our own olive oil, promoting a business vision based on quality, sustainability, and European collaboration.

My journey with O.N.A.O.O. began in 2023 with the Official Technical Course and continued through the Two-Year Professional Tasting Program, which I completed in 2026, qualifying as a Professional Olive Oil Taster.

Alongside my work in the olive oil sector, I am also a Mental and Motivational Coach

Iakovos Tzanakis

I work in my family’s olive oil packaging and trading company in Crete, Greece. My responsibilities include sales, quality control, product evaluation, customer support, and participation in olive oil tastings. My daily involvement in the extra virgin olive oil sector has inspired a strong interest in sensory analysis and quality assessment.

My journey with O.N.A.O.O. began three years ago and has provided me with a structured education in olive oil sensory analysis. Through courses, guided tasting sessions, and continuous training, I have developed the ability to recognize positive attributes, identify sensory defects, and evaluate olive oils using a professional tasting methodology.

Today, I apply these skills daily in olive oil quality management and commercialization. I work closely with producers, customers, and industry professionals, contributing to product selection and evaluation with the goal of connecting sensory quality with market requirements and consumer expectations.

For me, extra virgin olive oil is much more than a profession—it is a true passion. My experience with O.N.A.O.O. has significantly expanded my knowledge and tasting skills, and I look forward to continuing this journey while promoting the culture of high-quality extra virgin olive oil at an international level.
