Souroti is a premium sparkling mineral water sourced from a deep spring near Thessaloniki, Greece. Renowned for its crisp, refreshing taste, it boasts a high mineral content—approximately 1,350 mg of dissolved solids per liter—including calcium, magnesium, and trace elements like lithium and selenium. These minerals contribute to its distinctive flavor and digestive benefits. Historically, the water was naturally carbonated; today, carbonation is added during bottling to preserve its effervescence.
