Jenever, also known as Hollands, genever, genièvre, peket, or sometimes as Dutch gin, is the juniper-flavoured traditional liquor in the Netherlands, Belgium and adjoining areas in northern France and northwestern Germany. As an EU and UK Protected Designation of Origin the use of the term jenever and its soundalikes can only be used if the product is made according to the specifications in Belgium, the Netherlands, two northern French departments and two German federal states. Gin was developed in Britain after introduction of jenever to the island.

Junipers are coniferous trees and shrubs in the genus Juniperus of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of western, central and southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of 4,900 metres (16,100 ft) in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth.
