Whiskey, Lemon, Aperitivo Bitters, Amaro Liqueur 23% abv

From Tip Top:

"One sip and you’ll understand why this modern classic has achieved first-class status. Its delight is surely in its paradoxical flavor- it’s light and juicy yet complex and satisfying. The original creator, Sam Ross, describes this balance of flavor as “sherbet”, and we worked with him to get it just right. Tasting notes: tangy sherbet, vanilla, rich baking spices, bright lemon.
