Apparently, some water actually does come right out of the ground all bubbly. The Greeks and Romans drank it, or bathed in it, or something. Or so we would be led to believe.
(To be fair, too, all ground water is "mineral water" in the sense that it's got minerals in it: only distilled water is pure H2O.)
This website defines different types of bottled water. Natural sparkling water is defined as "naturally carbonated, but can have C02 replaced after treatment (not more than it contained originally)". This is presumably because some of the carbonation is lost on the way from the spring to the bottling plant: the rules allow the bottler to "freshen" the water, as it were.
You can pump CO2 through plain tap water and sell it as "sparkling water," but not as "natural sparkling water." This would, presumably, explain the existence of sparkling Ty Nant.
Or maybe Ty Nant comes out of the ground fizzy, and they just let some of it sit around and go flat. |
