A fruit shake is a chilled, blended and sweetened beverage which is prepared from fresh fruits. It may even contain chocolate. Apart from fresh fruits, fruit shake contains crushed ice, frozen yoghurt or honey. While some fruit shakes may be made from 100% fruit, others may contain fruit syrup for enhancing the taste. They may contain milk and they are somewhat thick in consistency. Fruit shakes gained popularity in the United States in the late 1960s. By the year 2000, fruit shakes were available in all major coffee shops and pre-bottled ones were available in supermarkets.
