Eco2Wine Training Week in Dijon: Flow cytometry and cell sorting
From December 8-11 2025
Following their training week in Tblisi, the Eco2Wine doctoral candidates (DCs) flew across Europe and regrouped for their second round of training at the University of Burgundy in Dijon. Hosted by Hervé Alexandre, this technical training aimed to equip the DCs with both a theoretical and practical understanding of flow cytometry. This technique, to be used by many of the DCs in their own research, utilizes fluorescence to characterize and sort cells.
Research engineer Nicolas Pernet introduced the DCs to the basics of cell sorting and flow cytometry.
The DCs were then tasked with applying their knowledge to detect and quantify the presence of Brettanomyces yeast in a wine sample, as well as determining the viability of yeasts and bacteria in different samples.

On the final day of training, the DCs hopped on a bus and made the drive into the heart of Beaujolais to visit the Eco2Wine associated partner Chateau de L’Eclair. This experimental winery, along with producing wine for commercial sale, runs many different test fermentations with the goal of adapting to climate change in the region.

The DCs were treated to a tour and tasting in the cellars at Chateau de L’Eclair.

It was an intense and technical week, but one full of useful knowledge and skills the DCs can apply to their own research going forward. It was a great way to finish out 2025 as the focus now shifts to the next round of training weeks in October 2026.
