PROFILO:

Born in Istanbul and graduated from Boğaziçi University in 2008. My journey in olive oil sector began during my professional career as a Brand Manager at one of Türkiye’s most established and respected olive oil brands. What started as a professional responsibility quickly transformed into a deep personal passion for olive oil and its cultural significance. This long-term professional exposure and knowledge of the entire value chain combined with a growing personal dedication to learning and tasting, ultimately led me to pursue formal training and certification with ONAOO.

I am currently working as a brand consultant mainly working with olive oil brands. Besides, I am olive oil panel member of Ayvalık Chamber of Commerce.

A few years later, the oleoteca grew, helping to spread oil culture. You can buy high-quality, mainly Italian oils, and you can also buy various EVO-based products (food and cosmetics), as well as books and guides about olive oil.

Murat Faik Ünver

Murat Faik Ünver, of Swiss and Turkish descent, was born and raised in Geneva, Switzerland. From a young age, he developed a deep interest in culinary arts and cooking. To pursue this passion, he studied Applied Sciences in Hospitality Management and Business Administration at Glion Hospitality School in Montreux.

After completing his university studies, he worked in the hospitality industry for a time, but he soon realized his true calling was to produce something from the land and engage in agriculture. To fulfill his aspirations, Murat returned to his roots in Turkey, where he planted approximately 3,000 olive trees and began cultivating his family’s land. Additionally, he acquired an abandoned olive oil factory, marking the beginning of his brand, Olivya Gökçeovacık. Since 2019, Murat and his team have been producing their own high-quality olive oil, supplying it locally to those who seek premium olive oil.

Over the years, they have garnered multiple awards, creating many moments of pride. Driven by his passion for creating and producing, Murat’s pursuit of becoming a certified olive oil sommelier will further enhance his expertise and enable him to continue excelling in his field.

Marketing

Started technical course in 2023, and graduated in 2025 November in Imperia.

Olive oil is a passion and a profession for me and I look forward to contributing to the global olive oil community.
