On September 30, 2022, from 5 p.m. to 10 p.m., in Marmontova Street in Split, we participated in the project named: Reconnect Science with the blue society (Blue-connect) as part of the HORIZON MSCA Researchers’ Night with the theme “The role of yeast in wine production“. We presented the project with a powerpoint presentation and brought different species of autochthonous yeasts from the Maraština variety that we developed on solid nutrient media. We presented the experiment of alcoholic fermentation of sugar to the general public in an interesting way, and with simple physicochemical methods, we approached the measurements that we perform on must and wine in the Enological Laboratory.
