Jenever (also known as junever, genièvre, genever, jeniever, peket or in the English-speaking world as Holland gin or Dutch gin), is the juniper-flavored and strongly alcoholic traditional liquor of the Netherlands and Belgium, from which gin evolved. Traditional jenever is still very popular in the Netherlands and Belgium. European Union regulations specify that only liquor made in these two countries, two French provinces and two German federal states can use the name jenever. Jonge jenever has a neutral taste, like vodka, with a slight aroma of juniper. Oude jenever has a smoother, very aromatic taste with malty flavours. Oude jenever is sometimes aged in wood; its malty, woody and smokey flavours lend a resemblance to whiskey. Jonge jenever is sometimes served cold from a bottle kept in a freezer. However, the higher-quality oude jenever (and korenwijn) is usually served at room temperature. When jenever is drunk with beer (normally lager) as a chaser, it is referred to as a kopstoot (headbutt) or duikboot (submarine) in Flanders. Traditionally, jenever is served in completely full shot glasses that have just been pulled from the freezer. The first step to drinking jenever properly is to keep the glass on the table, bend down to the glass and take the first sip without holding the glass. Once this traditional first sip is accomplished, one can drink the rest of the drink normally.
