Mango soda in New Zealand is usually a syrup flavour or a stevia can. Sidekick Mango is the fruit kind: real mango, New Zealand honey, a splash of apple cider vinegar, in a 250ml can. No cane sugar. No stevia. No erythritol.
It is the flavour people buy when they mean summer. Online it is the best seller.

What it tastes like
Juicy mango first. Honey is softer than cane-sugar syrup. A dry little finish from the vinegar — not a tropical slushie and not a diet aftertaste.
Drink it cold. Over ice. Or as the summer dirty soda: Mango coconut.
The mango fruit is North Queensland. Honey and vinegar are New Zealand. We do not call the whole range “NZ fruit soda.”
Calories and sugar
46 calories per 250ml can. Sugar sits under 4 g per 100 ml. The full table is How many calories in Sidekick. Check the can you are holding.
It is still soda. Is honey soda healthy? is the honest version of that question.
How to buy it
