Flos Olei – The guide that writes world olive oil standards

In the past 16 editions, this prestigious guide has repeatedly confirmed: Istria is at the very top of the world's olive growing regions.

Flos Olei is the most famous international guide to extra virgin olive oils, which, every year, brings together 500 of the best olive oil producers from the five continents. It is edited by the renowned Italian food and wine expert Marco Oreggia, and the oils are evaluated exclusively according to their organoleptic properties, based on tastings by a professional panel.

In addition to describing the oils themselves, Flos Olei also provides a cultural overview of the regions from which the producers come, highlighting local specialties and their contribution to the development of olive growing. Istria has been among the most prominent regions in the world for sixteen consecutive years, thanks to its exceptional quality, knowledge and sustainable approach to production.

Of particular note is the Mate oil mill from Savudrija, which has been included in the elite category – the Hall of Fame – for the second time, in the 2025 guide. This is an award given to producers whose olive oils have achieved top quality for many years, with a score of 100/100.

Mate Oil Mill thus found itself in the prestigious company of nine global producers who entered the Hall of Fame in 2025, side by side with the best Italian and Spanish oil mills.

If you are staying in Umag or the surrounding area, a visit to the Mate oil mill offers the opportunity to taste one of the best olive oils in the world, at the very source of its excellence.
