BevNet's reviewer nails it in one: Orange is more than a color, it should be a flavor, too. Unfortunately, Zota Orange is a vague sort of sweet-weak-citrus-tea blend without much flavor behind it.
Thin and "sparkly" rather than "carbonated," the beverage owes its flavor more to aroma than taste: a pronounced orange nose rising from the glass as it's poured and sipped is responsible for most of the orange character. Unfortunately, that isn't enough if you're looking for an "orange soda" in the tradition of Crush or Fanta.
I find the subtlety to be a nice change from stronger-flavored sodas, though, so I give the drink a solid three stars rather than the lower rating it would otherwise deserve.
