Perrier (French pronunciation: [pɛʁ.je]) is a brand of bottled mineral water made from a spring in Vergèze in the Gard département of France. The spring is naturally carbonated. Both the water and natural carbon dioxide gas are captured independently and in the bottling process, the carbon dioxide gas is added so that the level of carbonation in bottled Perrier is the same as the water of the Vergèze spring.
