Beyond coffee shops, Coca-Cola CEO James Quincey, himself a Briton who is familiar with the Costa brand, said Costa would provide an important growth platform ranging from beans to bottled drinks in what is one of the world’s fastest-growing drink categories, growing 6 percent. “Coca-Cola doesn’t have a broad, global portfolio in thi...
