The water of St-Yorre rise from the depths of the land of Auvergne to your glass, to deliver their benefits to you. The strong pressures which reign in the terrestrial depths, as well as the high temperature and the presence of carbon dioxide participate in its emergence. Throughout this journey, St-Yorre takes care of carbon dioxide and all the minerals that make it rich. The natural presence of carbon dioxide helps maintain its bacteriological purity. It is also this gas that gives it this unique sparkling.
