The launch brings the number of flavours in the range up to six and the new product has already won a listing in Tesco.
The pack design now has a clear area – so consumers can see the drink inside the bottle – and a reference to how the product is made with real fruit juice.
The range is being backed by a campaign on Facebook, Twitter and Instagram.
Brand manager Lorna Tweed said: “Caribbean Twist has experienced an increased rate-of-sale over the past year through new listings and a consumer desire for enjoying popular cocktail flavours at home.
“Peach Paradise complements the other fruity flavours within the range, and strengthens the brand’s appeal within the RTD segment.”
