This is an odd one to describe. The ingredients lists fruit juices from concentrate: grape, passion fruit, lemon and lime. It also lists ‘flavourings’… but, and critically, there is specifically no mango mentioned anywhere specifically. In a green mango flavoured drink. I’d never heard of a green mango before so I had to Google it, and the first result was a Wikipedia entry about a type of Hummingbird of that name. I’m assuming the drink doesn’t contain hummingbird as that might go against its vegan credentials. Anyway, regardless of what it’s called and what it does or doesn’t contain, it’s a tropical flavoured energy drink, and nothing fancier or more complicated than that.
