Sour apple liqueur is a sweetened fruit liqueur flavored to taste of tart green apple.
Candied green-apple sweetness with a sharp, tart edge and a crisp, slightly sour finish.
A small measure sweetens and flavors a shaken build, contributing both sugar and pronounced apple tartness; poured heavier, it can carry the dominant flavor of a drink.
Another green-apple fruit liqueur, or apple schnapps of comparable sweetness.
A neutral spirit base is sweetened and flavored with green apple, typically colored a bright pale green; sourness comes from the apple character layered over the sugar rather than from added acid.
