Syrups used to make drinks at bars are called many different things. Sometimes they are called a "simple syrups". Other times they are called "sugar syrups".

A variety of drinks call for sweetening to offer the tartness of some juices used in the drink recipes. Granulated sugar does not dissolve easily in cold drinks. Since bar syrup is a liquid, it is easily mixed with other liquids in cocktails, making it a perfect alternative for granulated sugar.

Juice is a fluid naturally contained in animal or plant tissue. This article is about the latter. For example, orange juice is the liquid extract of the fruit of the orange tree.

Juice will usually have a defined level of purity, in some countries of 100%. It should not be confused with a squash which is usually an artificial juice to be diluted with water. Common methods for preservation and processing of fruit juices incluide evaporation, spray drying, pasteurization and concentration.
