Dur-so means «Four Waters» in Turkiс dialects. According to a legend, Lake Abrau that now hosts a resort, vineyards and the famous winery with rock tunnels, originates from four springs. The water for the Dur-so 4 Waters collection originates in the foothills of North Caucasus. The spring is located near Durso marine harbour. According to microbiological research, the local artesian water is enriched by micro elements: magnesium, calcium, potassium and sodium, is very soft and pleasingly refreshing.
