Yum comes in Apple & Cinnamon Pie, Cherry Pie, Lemon Cheesecake, Summerfruit Trifle, Banoffee Pie and Rhubarb & Custard, with each bottle containing fewer than 20 calories.
Targeted at women aged 18 to 40 , the range will retail at 99p for a 20cl bottle.
"Although healthier lifestyles are important to today's consumers they don't want to compromise on taste and Yum is offering a big slice of guilt-free indulgence in a little bottle," a Vimto spokeswoman said.
Yum will be sold in selected high street retailers for three months from the beginning of May before rolling out nationally. A new website - www.whyfeelguilty.com - will support the launch.
