What is Perrier made of?

Perrier is a brand of naturally carbonated mineral water sourced from the Vergèze spring in the Gard département of France. It is composed primarily of water, which is rich in minerals such as calcium, magnesium, and bicarbonate, giving it a distinctive taste and effervescence. The carbonation is natural, resulting from volcanic activity in the region. Perrier is known for its refreshing flavor and iconic green bottle.
