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.

I joined the ONAOO family in March 2023, when I attended the official technical course, and then continued with the advanced course, which concluded in November 2025.
In the future, I would like to strengthen my connection with the ONAOO family in order to share and promote the culture and tradition of extra virgin olive oil around the world.

I began the ONAOO tasting course initially in March 2023. After passing the first stage, I then transitioned into the two-year advanced course in October 2023, and completed the course in November 2025.
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.
