Perrier is a French brand of natural bottled mineral water captured at the source in Vergèze, located in the Gard département. Perrier is best known for its naturally occurring carbonation, a distinctive green bottle, and higher levels of carbonation than its peers. The spring is naturally carbonated. Both the water and natural carbon dioxide gas are captured independently. The water is then purified, and in the bottling process, the carbon dioxide gas is re-added so that the level of carbonation in bottled Perrier matches that of the Vergèze spring.

The spring in Southern France from which Perrier is drawn was originally known as Les Bouillons. It had been used as a spa since Roman times. Local doctor Louis Perrier bought the spring in 1898 and operated a commercial spa there; he also bottled the water for sale. He later sold the spring to St.John Harmsworth, a wealthy British visitor.
