Watery. I guess on a run it might be quite refreshing – slightly flavoured so as to not be to sickly during high exertion. But, as an energy drink, it lacks a crucial detail of taste. It’s non-carbonated, yet caffeinated for an extra kick so it slips down easily and boots you several minutes later. Well, boot is probably the wrong word as it has a comparatively low caffeine content… maybe prod is a better word.
