Greece’s Green Cola has launched its product in the United States, which it counts as the world’s largest soft drink market. It is now expanding its cooperation with key retailers in the United States to include the Whole Foods supermarket chain. Having met the standards of the well-known chain, Green Cola will be present in more than 60 Whole Foods stores in Connecticut, New Jersey, as well as New York, beginning in September. The Greek producer of non-alcoholic drinks based on stevia has established a presence in seven American states since the beginning of the year, including Texas, Massachusetts and Connecticut.
