Coca-Cola Zero, the sugar-free version of Coca-Cola, was introduced in France in January 2007. Marketed as a low-calorie alternative, it contains no sugar and only 0.3 kcal per 100 ml. The drink uses a combination of sweeteners, including aspartame, a substance that has sparked debate over its health effects. While some consumers have embraced it as a healthier option, the classic Coca-Cola has not been replaced. Over nearly two decades, Coca-Cola Zero has found a place on French terraces and in homes, especially among those watching their calorie intake. The appeal of Coca-Cola Zero lies in its promise of the familiar taste of Coca-Cola without the sugar. This has made it popular in a society increasingly focused on diet and health. Lise, an osteopath and active individual, says she would never have considered the regular version. "I find the amount of sugar in Coca-Cola alarming," she says. "I always have a can of Coca-Cola Zero at home and at the bar—it feels more 'healthy,' even though it's still a soda." In the world of fashion and lifestyle, Coca-Cola Zero has also found a niche. Cécile de Boismenu, a former editor-in-chief of L'Officiel de la mode, recalls how the drink became associated with the industry. "Models would drink it before shows because agencies wanted them to stay slim without guilt," she says. "I've seen people bring bottles to private dinners—it was a revolution in a world obsessed with weight." The formula of Coca-Cola Zero includes carbonated water, caramel coloring, phosphoric acid, natural flavors, caffeine, and a mix of sweeteners, with aspartame being a key ingredient. While aspartame has been approved in France since 1988, it remains controversial due to concerns about its potential health risks. Some consumers, like Philippe, reject it entirely. "I find the taste of aspartame disgusting," he says. "I prefer the classic Coca-Cola—it's not just about guilt, it's about taste." Despite the popularity of Coca-Cola Zero, the classic version still holds its ground in many settings. A small survey in bars and restaurants showed that the traditional Coca-Cola was more frequently chosen, with 18 enthusiasts compared to 11 for the zero-sugar version, which was mostly women. Bartenders in cities like Toulouse note that while Coca-Cola Zero was once a trend, the original recipe is making a comeback. In some places, the ratio of classic to zero-sugar drinks is around 60% to 40%. While the zero-sugar version has found its place, the classic Coca-Cola remains a staple in French culture.
