Unfermented grape juice, also known as 'MUST' or 'STUM' (4 letters), is a non-alcoholic beverage made from freshly pressed grapes. It is a popular drink in many countries and is often used to make wine. The juice is unfermented, meaning that it has not been exposed to yeast or other microorganisms, and therefore does not contain any alcohol. It is typically sweet and can be enjoyed on its own or used as an ingredient in various recipes.
