Lurpak Lightest - the brand’s biggest launch in 10 years - has racked up £13.5m in first-year sales [Nielsen 52 w/e 22 December 2012] and achieved 7.5% household penetration [Kantar 52 w/e 23 December 2012]. Launched in a 500g tub format in January last year, it was followed by a 250g tub in May. Lurpak Lightest had enabled the brand to target households looking for a healthier spreadable product that still tasted great, said Lurpak.
