Best Sparkling Iced Tea – Fizzy Refreshment for Hot Days

Sparkling iced tea has finally landed properly in the UK, and it's about time. While America has been guzzling fizzy tea for years, our options have been limited to sugary supermarket experiments or expensive imports. Enter Twinings' new range: canned, carbonated green tea infusions that promise vitamins, zero added sugar, and actual tea flavour. We reviewed the lot to see if sparkling tea can hold its own against traditional iced tea when the mercury climbs.

The concept is simple—take a lightly brewed green tea base, carbonate it, add natural fruit flavours and a vitamin boost, then can it at 250ml. No artificial sweeteners, no added sugar (they use stevia and erythritol), and low caffeine levels mean you can drink them all afternoon without jitters or guilt. Each can delivers 30% of your daily vitamin C alongside minerals like magnesium or B vitamins, depending on the variant. It's a functional soft drink masquerading as a tea, and it mostly works.

We approached this round-up with two questions: do they taste like tea, and are they genuinely refreshing on a sweltering July day? The answers varied by flavour. All four products here are from Twinings' new wellness-focused line, split into "Boost," "Refresh," and "Defence" sub-ranges. If you're curious about making your own sparkling tea at home, we've covered that separately—but for grab-and-go convenience, canned is king.
