Some wine needs time to smooth out its tannin structure, but its age doesn't determine the water quality. Vintage does influence water, however. Very young waters like Cloud Juice don't have much time to absorb minerals, so they tend to have low TDS levels and hence light, neutral, and soft tastes. The age of water is less important than the local geology. The age of bottled waters should be noted as an enjoyable part of their backstories that adds to the epicurean pleasure of drinking them.
Fromin is 15,000-year-old well water from the last ice age in Europe, and Svalbarði is 4,000-year-old iceberg water. Tell the story about the vintage at your next party and compare it to the story of a 20-year-old Boudreaux, and you'll have people appreciate vintage in fine waters.
