Kirsch

Kirschwasser (, UK also, ; German for 'cherry water'), or just Kirsch (although this abbreviation is rarely used in Germany), is a clear, colourless brandy from Germany, Switzerland and France, traditionally made from double distillation of morello cherries. It is now also made from other kinds of cherries. The cherries are fermented completely, including their stones. Unlike cherry liqueurs and cherry brandies, Kirschwasser is not sweet. It is sometimes distilled from fermented cherry juice.

Serving
Kirschwasser is usually drunk neat. It is traditionally served cold in a very small glass and is taken as an apéritif. It is an important ingredient in fondue. People in the German-speaking region where it originated usually serve it after dinner, as a digestif.

Kirschwasser is used in some cocktails, such as the Ladyfinger, the Florida, and the Rose.

High-quality kirschwasser should be served around 16 C, warmed by the hands as with brandy.

Origin and production
Because morellos were originally grown in the Black Forest regions of Germany, kirschwasser is believed to have originated there. Kirschwasser is colourless because it is either not aged in wood or is aged in barrels made of ash. It may have been aged in paraffin-lined wood barrels or in earthenware vessels. ' Rivals in producing high quality "Kirsch" are Switzerland and Elsass (Alsace), the latter even has a kirschwasser route, and other quality cherry production german speaking areas like South Tyrolia. In France and in English-speaking countries, clear fruit brandies are known as eau de vie. The European Union sets a minimum of 37.5% ABV (75 proof) for products of this kind; kirschwasser typically has an alcohol content of 40%–50% ABV (80–100 proof). About 10 kilograms (22 pounds) of cherries go into the making of a 750 ml bottle of kirschwasser.

One French variety, Kirsch de Fougerolles , and two Swiss varieties, Zuger Kirsch and Rigi Kirsch, have been certified as appellation d'origine protégée (AOP).

Chemical composition
Compared with brandy or whisky the characteristic features of kirsch are that it contains relatively large quantities of higher alcohols and compound ethers, and the presence in this spirit of small quantities of hydrogen cyanide, partly as such and partly in combination as benzaldehyde-cyanhydrin, to which the distinctive flavour of kirsch is largely due.

Food
Kirsch is sometimes used in Swiss fondue and in some cakes, such as the Zuger Kirschtorte. It is also commonly used in the dessert cherries jubilee. It is used in traditional German Schwarzwälder Kirschtorte (Black Forest gateau) and in other cakes—for example in Gugelhupf cake.

Kirsch can also be used in the filling of chocolates. A typical kirsch chocolate consists of no more than one milliliter of kirsch, surrounded by milk or (more usually) dark chocolate with a film of hard sugar between the two parts. The hard sugar acts as an impermeable casing for the liquid content and also compensates for the lack of sweetness that is typical of kirsch. Swiss chocolatiers Lindt & Sprüngli and Camille Bloch, among others, manufacture these kirsch chocolates.
