Mineral Waters Are Strongly Flavored
Though none of our waters had any added flavorings, we still noticed an array of flavors in them, from saltiness to acidity to sweetness. The three mineral waters had the most pronounced flavors by far. Many tasters could identify them in our blind tasting because they had a characteristic salty and sometimes sulfurous, almost eggy flavor. While manufacturers aren’t required to disclose the type and amount of minerals in their water, our science editor explained that two common compounds found in mineral water are sodium and sulfites, which can contribute salty and eggy flavors, respectively. Tasters were split on the more pungently flavored mineral waters. Some loved the distinctive earthy taste, while others found the flavor too prominent. Ultimately, most mineral waters landed at the bottom of our rankings; our tasters preferred cleaner, more neutral options.
