Time to live up to your New Years’ resolutions of losing weight and living healthier. The Cologne-based retailer group REWE joined the chorus with an interesting marketing strategy. Supported by postcards with hashtag #dubistzucker (you are sugar, meaning: you are sweet), it offers consumers a sampler of its private label chocolate dessert with the original recipe and content of sugar, plus three pots, containing 20%, 30% and 40% less sugar than the original recipe.
