Now I'm not saying that some waters--especially mineral spring waters--can carry a strong taste of odd minerals, salts, sulfur or magnesium. (Most don't, and the ones that do are used to move one's bowels). But seriously? Do people really need a sommelier to help pair a water to go with food or (get this) with the wine they are drinking? When I lived in France years ago, I quickly learned that the Vittel ads showing arrows going into a man's mouth and coming out of his crotch meant something: That this particularly awful tasting stuff makes you pee like crazy--something the French think is simply wonderful. I stayed away from that brand after learning my painful lesson.
In Italy, the choices are many, but did I sense a drastic change in flavor between brand names? Not really. So in restaurants the only question asked was, "acqua naturale o gassata?" Plain water or gassy. The taste was always the same. Wet water or with bubbles. Am I thirsty or do I want to burp after my meal? That's the real question.
Water water everywhere and we have to bottle it, brand it and hire someone to tell us which one to drink...
