VERY disappointed with this product. I'm a big fan of grapefruit flavors and usually mix Walmart's flavored "Clear American" carbonated waters with sangria to make a delicious and refreshing homemade "wine cooler". Therefore, I was extremely surprised when, after mixing about a half-cup of La Croix Grapefruit water to a half-cup of water, the resulting taste was nasty and quite "off". I decided to try a few ounces of the water on its own and, sure enough, it had the same "off" taste. Today I tried the La Croix Lime water and, fortunately, it didn't have the same nasty taste.
