PepsiCo has confirmed details of the latest line extension for its Mountain Dew soft drink brand in the US.

The company's North America unit said today (19 August) that Mountain Dew Voltage, which contains raspberry citrus flavour and ginseng, was chosen - and developed - by US consumers online at The addition beat Mountain Dew Revolution and Mountain Dew Supernova in a vote to join the brand's stable on a permanent basis, after all three had been made available in the US for a limited time this summer.

"Through this groundbreaking promotion that attracted more than 1.6m to our site, we gave consumers unprecedented control over the brand and they delivered by developing three terrific products," said Frank Cooper, VP of portfolio brands for Pepsi-Cola North America.  "Consumers designed every aspect of the product, actively campaigned for it and finally elected it the next line extension."

Of the 350,000 votes cast by consumers to select a permanent addition, 42% voted for Voltage, the company said.

The new variant will be available nationwide from January.
