Italy's number one brand of sparkling mineral water was established in 1893, though Italians have been drinking from its source for hundreds of years. This naturally effervescent water is bottled directly at a spring located in the protected Sorgeto di Riardo Park near the extinct Roccamonfina volcano in Italy's Campania region. Ferrarelle is extremely mindful of the quality of its products, testing them more than 600 times each day. Care is also taken to safeguard the habitat surrounding the spring, and the company's bottling plants are powered by solar energy. Ferrarelle water, both sparkling and still, is bottled in glass containers rather than plastic, which protects its taste and purity and lessens the impact on the environment. Ferrarelle water begins as rainfall, which trickles through layers of rock in the ground, soaking up valuable minerals such as calcium, potassium, magnesium and fluoride. Nevertheless, it has no mineral taste and no unpleasant saltiness.
