Schnapps is a term that refers to any kind of strong alcoholic beverage.
In Austria, Switzerland, southern Germany, and the French region of Alsace, a type of Schnaps called Obstler or Obstbrand (from the German Obst, fruit) is very popular.
The main kinds of fruit used for German Schnaps are apples, pears, plums, and cherries. Apricots are another popular fruit; they are used to make an Austrian Schnaps called Marillenschnaps. Fruits other than these five kinds are rarely used for German Schnaps. Apples are used along with pears to make a fruit brandy called Obstwasser. Pears are used to produce Poire Williams (Williamsbirne); plums make Zwetschgenwasser, and cherries make Kirschwasser.
Another popular form of Schnapps is Kräuterlikör (herbal liqueur), with known brands such as Jägermeister, Underberg, Kuemmerling, Killepitsch and Wurzelpeter.
American schnapps are alcoholic beverages that are produced by mixing neutral grain spirit with fruit flavors or with other flavors. This mixture is then bottled with added sugar and (usually) glycerine, producing a smooth, syrup-like drink. Their alcohol content can be between 15% and 50% ABV (30–100 proof). American schnapps is available in a broad variety of fruit, berry, and spice flavors. These drinks technically fall into the category of liqueurs because of their added sugar content.
