Available in the on-trade from February and the off-trade from April, it will replace the existing Orange & Cranberry flavour. In-store POS will feature the strapline: Not the Usual.
Britvic said the changes were intended to broaden the brand's appeal to consumers.
Sales director Andrew Richards said: "Premium soft drinks have grown significantly over the
past few years, driven by consumers' increasing desire for high quality, great tasting choices. More than half of J2O's regular consumers claim they look forward to new flavour additions to the range."
Richards added that six years after its launch, J2O Orange & Cranberry had "reached the point of maturity".
