Mosto in Spain is also called "alcohol free wine", but in Andalucia "mosto" can also be a kind of wine. This one belongs to the alcohol free variety and is a kind of red grape juice, very sweet and specially pleasant when served very cold. It is a great alternative to fizzy drinks for children, and in Spain it is usually what kids drink while the grown ups are having wine on a festive occasion (and many adults keep drinking it after being legally allowed to drink alcohol). Ingredients: Grape juice from concentrated grape juice, acidifier (citric acid).
