Nestle SA is adding its first vegan milk chocolate to its products as the world’s biggest food company expands beyond meat alternatives. The Swiss food giant will start offering plant-based KitKat bars this year, called KitKat V, according to Alexander von Maillot, head of Nestle’s confectionery business. The product will be for sale online and at selected stores in a handful of markets including the U.K. as a test run before a possible wider rollout. The bar, which uses a rice-based formula as a milk substitute, took about two years to develop. The main challenge in making alternatives to milk chocolate is ensuring it blends well with cocoa and sugar for a creamy texture. Other substitutes, such as soy or almond formulas, can create off-notes, von Maillot said.
