Penicillin Cocktail Recipe Offers Warming Winter Drink

The Penicillin cocktail is a contemporary classic that offers a warming and complex flavor profile, making it an ideal choice for colder weather. This drink, often attributed to Sam Ross at Milk & Honey in New York City around 2005, has gained significant popularity for its unique combination of ingredients and its ability to provide comfort without relying on heat.

The core of the Penicillin cocktail consists of blended Scotch whisky, fresh lemon juice, and a homemade honey-ginger syrup. The blended Scotch provides a smooth, accessible base, while the lemon juice adds a bright, tart counterpoint. The honey-ginger syrup is a crucial element, offering a sweet and spicy complexity that complements the other components. This syrup is typically made by combining equal parts honey and water with fresh ginger, then simmering to infuse the flavors. The balance of sweet, sour, and spicy notes is key to the drink's appeal.

A distinctive feature of the Penicillin is the float of smoky Islay Scotch whisky added just before serving. This addition, often just a small amount, introduces a peaty aroma and a subtle smoky flavor that elevates the entire drink. The Islay Scotch, known for its characteristic smoky and medicinal notes derived from peat smoke used during malting, contrasts beautifully with the sweeter, brighter elements of the base cocktail. This layering of flavors creates a multi-dimensional drinking experience that is both invigorating and satisfying.

To prepare the Penicillin cocktail, one typically combines 2 ounces of blended Scotch whisky, 0.75 ounces of fresh lemon juice, and 0.75 ounces of honey-ginger syrup in a shaker with ice. The mixture is then shaken vigorously until well-chilled. The contents are strained into a chilled coupe or rocks glass, often over fresh ice if serving on the rocks. Finally, the float is created by gently pouring about 0.5 ounces of Islay Scotch whisky over the back of a spoon onto the surface of the drink. The result is a visually appealing cocktail with distinct layers of flavor and aroma, offering a sophisticated yet approachable drinking experience that has cemented its place in modern cocktail culture.
