All of these waters have bubbles. In Munich it's not about whether you want bubbles in your water or not. It is simply how much bubbles would you like in your water.
Even "extra still" which you have to wonder, "how can you be more still than 'still'?" has bubbles. That was my first taste. So then I opened them all and put them in order of "bubbliness." Classic, naturally, was the "bubbliest." (Like the good ol' days.)
