Springing from a source in Wales’ Cambrian Mountains, this carbon-filtered sparkling water first made a name for itself in London's high-end hotels in 1989. The water is naturally filtered through mineral deposits approximately 450,000,000 years old. Today, the lightly carbonated beverage is more widely distributed and imported to the United States. The water is bottled in a green factory designed to lower environmental impact of production. Ty Nant is recognizable by its striking blue glass bottles, the hue that apothecary bottles were colored during the Victorian era.
