Sunny D bosses are hailing a 52% leap in sales over the past quarter as evidence the brand has finally turned the corner despite a further slump in its year-on-year figures.

Twelve months ago, Sunny Delight Beverage Company slashed the drink's fruit juice content from 70% to 15% and cut its price by 18p per litre in a bid to stem its rapid decline after a 39.3% fall in sales to £6.8m [SymphonyIRI 52w/e 23 January 2010].

Recent sales data showed the company's decision to go back to Sunny D's roots which had come a year after a revamp pitching the brand as a healthier product had slowed the year-on-year value decline to 17.1% [SymphonyIRI 52w/e 19 March 2011].

Over the past quarter, sales had actually shown strong growth, claimed the company. "With 12-week sales data showing a 52% increase in value and 56% increase in volume [SymphonyIRI 12w/e 16 April], things are moving in the right direction," said UK & Ireland area manager Richard Baragwanath.

Growth was ­being driven by the new formula, good weather and remerchandising of the chilled juice category by ­retailers, he said.

According to branding expert Kate Waddell, the move back to being a low-juice content drink had given Sunny D a credible and transparent brand promise.

"This is the brand being honest about what it is, which is a brand that majors on taste and convenience," said the managing director of brand consultancy Dragon Rouge "The healthier relaunch felt rather desperate and a case of the emperor's new clothes," she added.
