PepsiCo has launched an extension to its Sierra Mist soft drink portfolio.

Sierra Mist Ruby Splash is a blend of the lemon-lime taste with an extra ruby grapefruit-flavour and will be available "year round", the company said today (8 April).

Other Sierra Mist flavours include Lemon Squeeze, Undercover Orange and Sierra Mist Cranberry Splash, which has been offered for a limited time over the past three holiday seasons.

Sierra Mist Ruby Splash is offered in regular and diet versions of 20oz bottles, 2-litre bottles and 12-packs of 12oz cans.

The launch will be supported by a full slate of TV, radio and digital advertising, highlighted by the tagline, "It's Liquid Sunshine."
