South Korean volcanic water brand 16 Jeju sources its product from a volcanic island off the cost of the island nation. The 1,600,000 year old active volcano at the center of the island has created a layer of volcanic rock that is rich in minerals. There, water that is untouched by other environmental factors passes through the bedrock, a porous natural filter that purifies the water, making it perfect for consumption. The resulting water has a taste that is crisp, pure and refreshing due to its mineral content and the fact that it has not been processed excessively. Using natural resources to avoid excessive processing of water is a matter of focus for the brand. 16 Jeju volcanic water is available in multi packs in two sizes. Shoppers can purchase 16.9 fl oz bottles in packs of 6 or 20. 33.8 fl oz bottles in packs of 12 are also available.
