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.

Giuseppe was born in a small town in the province of Foggia, San Giovanni Rotondo.

For work reasons he moved to Campania, where he still lives today.

Strongly tied to the memories of his beloved Puglia, Giuseppe decides to open a farm to be able to carry on the family business to which his father has dedicated himself for more than 50 years; in the middle of the Tavoliere delle Puglie, every year 2,400 olive trees are finely selected in order to offer the best extra virgin olive oil.

In order to enrich his knowledge, Giuseppe decides to start his training course in the ONAOO School in 2018 and ended in 2021: after passing the exams of the Advanced Course, Giuseppe obtains the qualification of ONAOO Professional Taster.

In addition to the training activities, Giuseppe participated in the ONAOO Meeting in 2020 and other online tasting activities also organized by the School.

Olive oil is far more than a food – it’s a world of culture, community, science, and craftsmanship. I’m grateful to be part of this journey of discovery, deepening my understanding, and sharing that knowledge with others.
