Ocean Spray is swelling the ranks of its yogurt portfolio with its first probiotic offerings and a new fat-free range.

Manufactured by Highgrove, the new lines aim to make the most of health benefits associated with cranberries.

The three probiotic Ocean Spray Plus newcomers contain natural plant extracts. All are low-fat and cranberry-based, with either blueberry and guarana - claimed to boost energy, redcurrant and ginseng - to ease stress - and pink grapefruit and green tea for a healthy heart. Each 170g pot has fewer than 165 calories and retails at 49p. Initial trial price is 35p.

The fat-free newcomers come in four-packs featuring cranberry yogurt blended with blueberry, mango, melon or peach. Sweetened with Sucralose, the 125g pots have fewer than 65 calories each. Rsp is £1.39, with introductory offers of 99p or two packs for £2.

The Ocean Spray brand is to get £6m support next year including TV ads, with the yogurts getting specific direct mail, price promotions and cross-communication on all Ocean Spray juice packs.
