Osman, who is passionate about olives and olive oil, grew up in Izmir, one of the major olive producing regions of Turkey.

He has extensive experience in blending and sensory evaluation in the tobacco business since 1996 and is currently a master blender and panel leader in a leading global tobacco company. In 2019, he decided to expand his sensory knowledge in olive oil with ONAOO’s technical course.

After two years of training, he obtained the qualification of Professional Taster of ONAOO in 2023. He provides consultancy to farmers and olive oil producers in Turkey and product experience in Switzerland.

I began my technical course at ONAOO in September 2022, building a strong foundation in extra virgin olive oil quality standards, and evaluation. In February 2023, I started the ONAOO Professional Tasting Course, further developing my sensory analysis skills and ability to assess EVOO based on official tasting methods. I completed my ONAOO course in November 2025.

Extra virgin olive oil is more than a product to me, it is a symbol of history, culture, and tradition that has been valued for thousands of years across the Mediterranean. From ancient civilizations that used olive oil for food, health, and daily life, to modern producers who preserve traditional methods while improving quality standards, olive oil has always represented purity, resilience, and connection to the land and people.

I am proud to be part of this long heritage by sourcing only exceptional EVOO and promoting oils that are authentic, fresh, and truly representative of their origin. I am committed to continuous learning and to maintaining the highest standards in quality, traceability, and transparency, so customers can experience olive oil the way it was meant to be fresh, healthy, and deeply rooted in history.
