Apple schnapps is a sweetened, apple-flavoured liqueur built on a neutral spirit rather than a distilled fruit brandy.
Sweet and syrupy, dominated by a pronounced apple aroma that ranges from ripe orchard fruit to tart green apple, with little acidity or bitterness.
Serving as a flavour modifier and sweetener, it carries apple character into a build and is shaken or stirred in small to moderate measures; where it forms a larger pour it supplies the drink's core apple identity.
Another apple liqueur is the natural swap; a drier apple product such as apple brandy works with added sugar to restore body and sweetness, but the apple aroma cannot be reconstructed from any non-apple ingredient.
Apple brandy / Calvados / applejack
Apple brandy is a spirit distilled from fermented apples, so its apple character is distillate-derived, and it is dry and higher-proof; apple schnapps is a sweetened neutral-spirit liqueur carrying added apple flavouring, sweeter and lower in proof.
Continental apple Schnaps (Obstler-type)
German and Austrian apple Schnaps is a clear, dry, unsweetened fruit brandy distilled from fermented apples, typically 32%+ ABV; the English-market apple schnapps is a sweetened compounded liqueur, usually 15–30% ABV.
Apple schnapps takes a neutral grain spirit and adds apple flavouring or essence along with sugar (and sometimes glycerine), yielding a smooth, syrup-like liqueur. In the English-language commercial sense the product need not contain any distilled apple spirit at all, since the flavour comes from added essence; the word derives from German 'Schnaps', which in German refers to any strong dry spirit, while the sweetened flavoured-liqueur meaning is the American and British usage.
