I've never had Kool-Aid so I don't know what it tastes like. Over here we've pretty much always had (other than OJ) fizzy orange like Fanta or Club, basically carbonated coloured/flavoured water; goes right up your nose and burns your chest and gives you tremendous wind, or "diluted orange", like MiWadi or Robinsons or Kia-ora, which is, as it sounds, concentrate to which you add water. It can be very tangy (no pun intended) or it can taste like weak flavoured water, depending on how much water you put in it.
