I love these "Zero" drinks that the Coke company is making.
Coke Zero, Vault Zero, Powerade Zero, Sprite Zero, etc. taste very similar to the real thing and they taste very good for a low calorie drink.
Sprite Zero is no exeption, great refreshing taste especially when you freeze the can, it almost tastes like the regular Sprite, which is great.
Great choice for a drink if you're watching your calorie intake or just want something to drink.
