Vintage
The age of bottled waters should be noted, though, as an enjoyable part of their backstories, which add to the epicurean pleasure. Wine needs time to smooth out its tannin structure, but the quality of mineral water is not determined by its age. Vintage does influence water, however. Very young water and bottled Rain Waters don’t have much time to absorb minerals, so they tend to have low TDS levels and hence light, clean tastes. Old water may feel more substantial due to the higher Minerality.
