Crab apples (Malus sylvestris) otherwise known as the European apple are a small variety of apple commonly used for the production of jam and wine. They have the reputation of being sour, and therefore do not tend to be eaten raw. Dan Salaman. Attribution-NonCommercial 4.0 International (CC BY-NC 4.0). Source: Wellcome Collection.
