Jenever (Dutch: [jəˈneːvər] (listen), English: //), also known as Hollands, genever, genièvre, peket, or sometimes as Dutch gin (archaic: Holland gin or Geneva gin), is the juniper-flavored traditional liquor in the Netherlands, Belgium and adjoining areas in northern France and northwestern Germany. The European Union regulations specify that only liquor made in these two countries, two northern French departments and two German federal states can use the name jenever/genever/genièvre. Gin was developed in Britain after introduction of jenever to the island.
Jenever was originally produced by distilling malt wine (moutwijn in Dutch) to 50% ABV. Because the resulting spirit was not palatable due to the lack of refined distilling techniques (only the pot still was available), herbs were added to mask the flavour. The juniper berry (which comes from the Latin juniperus), hence the name jenever (and the English name gin), was used for its alleged medicinal benefits.
There is tradition that attributes the invention of jenever to the Dutch chemist and alchemist Franciscus Sylvius de Bouve (1614–1672). However, the evidence suggests that jenever was already known and used as a medicine in the 1500s. Already by 1606 (several years before Sylvius's birth), the Dutch had levied taxes on jenever and similar liquors as alcoholic drinks, suggesting that jenever had by then stopped being considered a medicinal remedy. Furthermore, prior to Sylvius's tenth birthday, jenever appeared in Philip Massinger's 1623 play, The Duke of Milan, which referred to the drink as "geneva". Geneva was the Anglicized name for jenever (even though the drink has no relation to the Swiss city of Geneva), a name that English soldiers had brought back with them when returning from battle in the Low Countries, first in 1587 (well before Sylvius's birth) and again during the early 1600s.
There are two types of jenever: oude (old) and jonge (young). This is not a matter of aging, but of distilling techniques. Around 1900, it became possible to distill a high-grade type of alcohol almost neutral in taste, independent of the origin of the spirit. A worldwide tendency for a lighter and less dominant taste, as well as lower prices, led to the development of blended whisky in Scotland, and in the Netherlands to Jonge Jenever. During the Great War, lack of imported cereals, and hence malt, forced the promotion of this blend. Alcohol derived from molasses from the sugar beet industry was used as an alternative to grain spirit. People started using the term oude for the old-style jenever, and jonge for the new style, which contains more grain instead of malt and can even contain plain sugar-based alcohol.
In modern times, jenever distilled from grain and malt only is labelled Graanjenever. Jonge jenever can contain no more than 15% malt wine and 10 grams of sugar per litre. Oude jenever must contain at least 15% malt wine, but no more than 20 g of sugar per litre. Korenwijn (grain wine) is a drink very similar to the 18th-century-style jenever, and is often matured for a few years in an oak cask; it contains from 51% to 70% malt wine and up to 20 g/l of sugar. Although the name oude jenever does not necessarily mean that the jenever is in fact old, there are some distilleries that age their jenever in oak barrels.
About 90% of all Jonge Jenever sold on the market is a blend from malt wine produced by Filliers in Belgium, sugar beet or grain based ethylalcohol from factories in Germany, France and (mostly) Russia and water. Most of the bigger brands contain no malt wine, so resemble in essence vodka. Distilleries in Belgium and the Netherlands actually distilling jenever mostly produce limited volumes of specialty drinks.
A note concerning Korenwijn: The term Korenwijn is a generic name, while the name Corenwijn is a brand name owned by Dutch company Lucas Bols.
Jonge jenever has a neutral taste, like vodka, with a slight aroma of juniper and malt wine. Oude jenever has a smoother, very aromatic taste with malty flavours. Oude jenever is sometimes aged in wood; its malty, woody and smoky flavours resemble whisky. Different grains used in the production process – such as barley, wheat, spelt and rye – produce different flavoured jenevers. The taste is sometimes enhanced by adopting barrels previously used for American whiskey.
Hasselt, Deinze, Aalst and Liège in Belgium, and Schiedam, Groningen, Amsterdam and Delft in the Netherlands, are well known for their jenevers and often referred to as "jenever cities" (jeneversteden). In Amsterdam, jenever is made by The Stillery, Van Wees and Wynand Fockink. Well-known Schiedam jenever distilleries include Nolet, Onder De Boompjes, Pit and De Kuyper. Near the Dutch-Belgian border, in Baarle-Nassau, Zuidam produces traditional jenevers and Dutch liquors. Other jenever-cities in the Netherlands are Groningen (Hooghoudt) and Dordrecht (Rutte Distillery). In Belgium, Deinze is very well known as for the Filliers distillery and Aalst is well known for Stokerij De Moor and Stokerij Van Der Schueren, both still active today. Also with the Biercée Distillery in Wallonia, one of only two Belgian distilleries to export their genever to the USA.
Dutch-based Lucas Bols produces and sells oude genever, known as ginebra in Spanish, in South America. Ketel One is now more known for producing vodka, but started out as, and still is, a jenever distillery.
Traditionally the drink is served in a tulip-shaped glass filled to the brim, with the surface tension enabling the jenever to rise higher than the glass's edge. Jonge jenever, colloquially a jonkie ("young'un"), is usually served at room temperature, sometimes (though this is now quite old fashioned) with some sugar and a tiny spoon to stir. The drink is sometimes served cold from a bottle kept in a freezer or on the rocks (jonge met ijs). The higher-quality oude jenever (and korenwijn) is usually served at room temperature. When jenever is drunk aside beer (normally lager) as a chaser, it is referred to as a kopstoot (headbutt), when the glass of jenever is dipped into the beer glass it is called a duikboot (submarine) in Flanders and the South of Holland. Traditionally, jenever is served in full shot glasses taken directly from the freezer. As the glass is very full it is advisable to take the first sips without holding the glass, leaving it on the table and bending one's back to apply one's mouth to the glass.
