Alia El Askalany

Alia has added a new skill to her culinary & gastronomy portfolio, being the first Egyptian female chef to hold a certificate as an advanced professional olive oil taster & sommelier from ONAOO Scuola in Liguria, Italy (The National Organization of Olive Oil Tasters).

Through her tasting skills & extensive practice, Alia has started a wave of awareness & tasting events across Cairo by partnering up with premium Egyptian olive oil brands as well as taking it internationally via harvest retreats/gastro-tourism across the Mediterranean.

Guests, chefs & enthusiasts are invited to explore the world of extra virgin olive oil by understanding the harvest process, touring olive groves, doing professional tasting sessions to look out for flavor notes & positive attributes of the different oil varieties and taste and pair each variety with different dishes through her curated menus.

I am very looking forward to continuing my educational journey into the world of olive oil with ONAOO and its network of tasters and professionals in the field, and also look forward to also educating more clients through my work.

Demetris Taliotis

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.
