A few of us have been looking into which drinks are suitable vegetarians in terms of ingredients and the processes used to make them. Coca-Cola signposted me to this page, where it clearly states, which drinks are not vegetarian. However, they can’t tell me if animal products are used within the process of making them. Unlike the ingredients that are used; processes don’t have to be declared! Therefore, some fruit juices may be clarified using gelatine and the companies doing this, don’t have to tell us!
