I chilled a 6 pack (since I normally drink ice water), and then followed the instructions to drink it within 15 minutes, from the can, which I normally don't do because I don't like the taste or smell of metal containers.
I didn't need to worry. The can did not impart any flavor to the water, nor was there any metallic or other odors. In terms of taste, the flavor was very clean, like you'd expect from a spring. I have a well, so my water is not chemically treated and the NXT LVL water tasted better than mine, which is great so..
It was also very crisp, not thick or heavy, had no metallic or any other aftertaste and when I finished it, I felt energized. Not jittery or jumpy, or medicated in any way, just oddly (nicely) and noticeably refreshed.
As it's marketed as a recovery product, I'm really excited to see how I feel after working out.
