Emanuel Andrietti was born in Ventimiglia (IM) on February 1, 1976, and holds a degree in law.
From an early age, he has been engaged in the family-owned olive oil enterprise, which was established by his father in 1945. He has come to recognize the necessity of acquiring a comprehensive understanding of the trade, given his role as the sole heir.
His father, who had him at an advanced age, remains his primary source of guidance and support at the age of 94. Approximately ten years ago, he made the decision to also enter the production side of the business. In collaboration with three colleagues, he acquired an existing olive press in Dolceacqua (IM), which had previously been utilized exclusively for third-party processing.
The press was entirely renovated and transformed into a new, continuously expanding agricultural enterprise that focuses on the cultivation and production of extra virgin olive oil made exclusively from Taggiasca olives.
In 2024, he successfully completed his training at the National Organization of Olive Oil Tasters (ONAOO), earning the title of “Professional Taster.”
I work in an Italian supermarket in Denmark, and for the past 20 years I have mainly focused on oils and balsamics. This has also allowed me to stay in contact with many producers in these sectors. I come from a family of olive oil producers, who from a young age instilled in me a passion, culture, and respect for this wonderful product.
My future projects include becoming an increasingly skilled and up-to-date olive oil taster, and possibly a Panel Leader here in Denmark.
Since 2020, she has been cultivating an olive grove in Puglia using entirely natural methods.
Using the expertise she has learned from local farmers and consolidated through her training at O.N.A.O.O., she covers the entire production chain — from land maintenance and pruning to harvesting, pressing, packaging and exporting — all carried out according to best practices.
In Switzerland, she offers her professional expertise to innovative companies in the olive oil industry, organises tastings and workshops.
She is involved in the fight against Xylella, a devastating disease affecting olive trees (https://www.tvsvizzera.it/tvs/qui-italia/quegli-svizzeri-e-quelle-svizzere-impegnati-nella-lotta-contro-la-xylella/78291581).

Demetris Taliotis is the Chief Olive Oil Obsessive at Aparthenasa, an award-winning agrocraft estate focusing on the production of terroir-driven extra virgin olive oil from Cyprus. He is a graduate of the prestigious Expert Course in Virgin Olive Oil Tasting of the University of Jaén and a jury member to numerous international olive oil competitions. His varied involvement with olive oil spans a multifarious career in agri-food and FMCG marketing, location and countryside management, and expansive research interests at the cross-sections of transversal agriculture, disruptive innovation, organoleptic variability and the cultural and creative industries.
Demetris firmly believes in the de-commodification of micro-produced olive oil, through the exploration and promotion of the variety and variability of its organoleptic profiles, in a way that enhances the sensorial pleasures consumers can relish from Extra Virgin Olive Oil.
