Yeah I originally thought it was carbonated as well when I first saw it (which I drink a lot of). Never had the misfortune of buying one though.

The white can is the only flat water; the black can and the flavored ones are sparkling.

(I tend to drink more Waterloo or Spindrift when not at a bar, personally, but I've enjoyed the flavored Liquid Death that I've had.)
