5 (5) Carling
Sales: £312.6m Growth: -7.5%
It may have had £25.3m wiped off its value in the past year, but Carling has a few tricks up its sleeve. With the core brand still declining, Molson Coors is looking to (you guessed it) low-abv fruit-flavoured variants. Carling Zest - launched March 2012 - has racked up range sales of £13m in its first year and Carling Cooler soft-launched in Asda last month.
