A tart apple-flavored spirit, this sour apple schnapps liqueur tastes great in fruit forward cocktails, like an apple martini or a Fizzy Apple cocktail. Mr. Boston Sour Apple Schnapps is also an excellent cordial for adding a sour apple twist to traditional cocktails and using with other cordials in layered drinks. Enjoy on the rocks or in a brandy snifter at room temperature or warmer to better enjoy the sweet-tart aromas.
