A chocolate laboratory in Italy is set to benefit both chocolate lovers and farmers, as it explores the future of chocolate bars. Celleste Bio has launched its first milk chocolate bars made with cell-cultured cocoa butter, paving the way for lab-grown chocolate to potentially hit supermarket shelves by 2027. In the UK, significant changes in chocolate offerings are expected in supermarkets from that year. Meanwhile, a laboratory dedicated to checking chocolate quality could make Willy Wonka proud.
