Slovenian Olive Oil Named Best In Northern Hemisphere with the Help of BioComplex for Crops


We’re proud to announce that our client Vanja Dujc, a Slovenian olive grower, has recently been awarded one of the most coveted awards in the industry.  His extra virgin olive oil, Vanja, has won the prestigious Olio Nuovo award for the best olive oil in the northern hemisphere in 2021.

World's Best Olive Oil

Using BioComplex for Crops on Olive Trees


Based in Koper, Slovenia, Vanja has been using Ekogea’s BioComplex 900 on his 1,200 olive trees, producing 3,300 litres of oil, since 2016.  BioComplex 900 is applied to improve soil structure and available nutrients for the plants, and to improve plant health by encouraging stronger roots and better nutrient uptake.  Our clients have reported that this has led to:

  • Significant (up to 30%) increase in crop yield
  • Increase in the quality of fruit, including oil content and natural flavour
  • Aroma of olives more fully expressed leading to higher quality oil product
  • Treated trees are healthier and more resistant to disease, frost and drought.

International Awards


The jury, comprised of gastronomy experts and top chefs, and was chaired by Michelin-starred chef Eric Briffard, the head of the Paris Le Cordon Bleu institute.  They were clear in their praise for the quality of Vanja’s olive oil which was described as a “wonderful, complex oil, balanced and with a fiery kick at the end”.  

Recently dubbed the “olive oil whisperer”, this is not the first time that Vanja has received international acclaim for his produce.  The first time he became a world champion was at the first olive oil world championships, organised as part of the Expo 2010 in Shanghai.
