How are German mineral waters legally differentiated from seltzers artificially carbonated elsewhere?
They must derive their source water from a recognized underground mineral source
German mineral waters are subjected to rigorous regulations that distinguish them significantly from water that might merely be carbonated tap water and bottled elsewhere. A critical requirement is that genuine German mineral water must originate from a recognized, certified underground source. This ensures that the water possesses its inherent mineral profile naturally. This regulation is key because it guarantees that the product is not simply municipal water that has been artificially infused with carbon dioxide and bottled, which is sometimes the case for seltzers in other international markets. The mineral content, which can vary regionally, is therefore inherent to the sourced water itself.
