To elevate this cocktail, a generous pour of smooth bourbon (we’re partial to Woodford Reserve or other small batch labels) adds warmth and depth. A few dashes of bitters bring balance, while muddled herbs and citrus give this drink a refreshing edge. Whether you serve it in a rocks glass, old-fashioned glass, or elegant cocktail glass, this is one of those whiskey cocktails that always feels special.

And if you’re into experimenting, try swapping in blackberry brandy, a splash of blackberry liqueur, or even topping with club soda or ginger beer for a bubbly variation.
