Quézac mineral water emerges naturally from the Diva spring, near the entrance to the village, in exceptional surroundings which have been naturally protected for centuries. This pleasant-tasting water is rich in mineral salts and trace elements and is also well-known to be beneficial for the stomach. The spring's water actually comes from Mont Aigoual. According to scientific studies, it takes 30 to 40 years for it to re-emerge in Quézac, after first settling in aquifers, where it acquires its effervescence naturally (rare in France).
