Rubicon is launching what it claims is the first sparkling pomegranate drink in the UK, building on the popularity of the flavour.

The drink will be available from this month in 330ml cans that flag up its polyphenol content. Polyphenols are powerful antioxidants which, says Rubicon, have anti-inflammatory properties and can help boost the immune system.

Each can contains the same levels of polyphenols as half a cup of green tea.
