The Jar Tales Whiskey Sour is the ultimate cocktail beloved by many. Shake before opening to activate the foam. Shake again as needed (don't forget to put the lid back on!). Serve chilled. All The Jar Tales cocktails are 100% Irish-made single-served ready-to-drink beverages sold in jars. Natural sediment may occur, easily removed by shaking the jar. ABV: 15.5%
