Juices are made by squeezing the juice out of the fruit . In the United Kingdom the name of a fruit or fruits followed by juice can only legally be used to describe a product which is 100 % fruit juice , as required by the Fruit Juices and Fruit Nectars ( England ) Regulations and the Fruit Juices & Fruit Nectars ( Scotland ) Regulations 2003 . However a juice made by reconstituting concentrate can be called juice .
