Barley Water

Barley water, usually flavoured with lemon or other fruit, is a traditional British tisane. It is made by boiling washed pearl barley, straining, then pouring the hot water over the rind and/or pulp of the fruit, and adding fruit juice and sugar to taste. The rind may also be boiled with the barley.

Drinking boiled grain in water, strained or not, is an ancient practice. Kykeon (Gr. κυκεών, from κυκάω, "to stir, to mix") was an Ancient Greek drink made mainly of water, barley and naturally occurring substances. It was used at the climax of the Eleusinian Mysteries to break a sacred fast, but it was also a favourite drink of Greek peasants.

A Scottish example is atholl brose which is made with oats. In Mexico grain-based aguas frescas are made by street vendors using similar methods. Roasted barley tea is a popular traditional Asian equivalent.

Barley water has been used as a first baby food, before feeding with barley mush. It is also used as a home remedy for cystitis.

In Britain, Robinsons Lemon Barley Water, now a Britvic brand, is sold in bottles of 850ml of sweetened concentrate, which is usually diluted with three to five parts cold water. Orange Barley Water is also available, as well as eight varieties of what the company calls "Fruit & Barley" drinks.

Robinsons Barley Water has a long association with Wimbledon, having been the "Official Still Soft Drink" to the Championships since 1934.
