The first confirmed date for the production of gin is the early 17th century in Holland, although claims have been made that it was produced prior to this in Italy. In Holland it was produced as a medicine and sold in chemist shops to treat stomach complaints, gout and gallstones. To make it more palatable, the Dutch started to flavour it with juniper, which had medicinal properties of its own.
Gin is a spirit which derives its predominant flavour from juniper berries (Juniperus communis). From its earliest origins in the Middle Ages, gin has evolved over the course of a millennium from a herbal medicine to an object of commerce in the spirits industry. Gin was developed on the basis of the older Jenever, and became popular in Great Britain when William of Orange, leader of the Dutch Republic, occupied the English and Scottish thrones with his wife Mary. Gin is one of the broadest categories of spirits, represented by products of various origins, styles, and flavour profiles that all revolve around juniper as a common ingredient.
