Evian is a popular brand of natural mineral water sourced from the French Alps, known for its purity, crisp taste, and balanced mineral content (like calcium, magnesium, potassium) after filtering through glacial rocks for over 15 years. Bottled directly at the source in Evian-les-Bains, it's a natural, low-sodium water suitable for everyday hydration, available in various sizes, and recognized for its distinctive smooth taste and premium image, though it has faced scrutiny regarding sustainability claims.
