The Penicillin cocktail is a modern classic that combines blended Scotch, smoky Islay Scotch, honey-ginger syrup, and fresh lemon juice for a drink that’s warm, spicy, and a bit mysterious. Created by bartender Sam Ross in the early 2000s, the Penicillin has become a favorite for those who appreciate complex, spirit-forward cocktails. With its balance of smoky Scotch, zesty ginger, and bright lemon, this drink is perfect for cooler weather or anytime you’re in the mood for something a bit different. Let’s explore the history, unique qualities, and recipe for crafting the perfect Penicillin at home.
The Origins of the Penicillin Cocktail
The Penicillin was created by Sam Ross, a celebrated bartender known for his work at New York City’s Milk & Honey. Ross developed the cocktail as a tribute to the soothing, medicinal qualities of ginger, honey, and lemon—ingredients often used in remedies for colds and sore throats. By adding smoky Islay Scotch as a float, he created a drink with a warming, complex profile that’s reminiscent of the classic Hot Toddy, but with a unique twist.
The Penicillin quickly became a hit and has since gained a reputation as a staple of modern cocktail culture. Its popularity is a testament to the appeal of its balanced flavors and distinctive ingredients, making it a go-to choice for both Scotch lovers and adventurous drinkers.
What Makes the Penicillin So Unique
The Penicillin is distinctive for several reasons:
- Complex Layered Flavors: With the combination of blended Scotch, smoky Islay Scotch, honey-ginger syrup, and lemon juice, the Penicillin offers a rich balance of smoky, sweet, spicy, and sour notes.
- Warming and Comforting: The flavors of ginger, honey, and lemon create a cozy, comforting experience that’s perfect for cool weather or whenever you’re feeling under the weather.
- A Modern Classic: Despite being a relatively recent creation, the Penicillin has earned its place as a contemporary classic, admired for its innovative use of Scotch and ginger.
How to Make the Perfect Penicillin Cocktail
The Penicillin requires just a few ingredients and is fairly easy to make, though you’ll need to prepare a honey-ginger syrup. Here’s the classic recipe for this smoky, spicy cocktail.
Classic Penicillin Recipe
Ingredients:
- 2 oz (6 cl) blended Scotch
- ¾ oz (2.25 cl) fresh lemon juice
- ¾ oz (2.25 cl) honey-ginger syrup (see recipe below)
- ¼ oz (0.75 cl) smoky Islay Scotch (such as Laphroaig or Ardbeg)
- Ice
- Lemon wheel or candied ginger for garnish (optional)
Honey-Ginger Syrup Recipe
Ingredients:
- ½ cup honey
- ½ cup water
- 2–3 inches of fresh ginger, peeled and sliced
Instructions for Honey-Ginger Syrup:
- Combine honey, water, and ginger in a saucepan.
- Bring to a gentle simmer, stirring to dissolve the honey.
- Simmer for about 10 minutes to infuse the ginger flavor.
- Remove from heat and let cool, then strain out the ginger slices.
- Store the syrup in a sealed container in the refrigerator for up to a week.
Instructions for the Penicillin:
- Combine Ingredients: In a cocktail shaker, add the blended Scotch, lemon juice, and honey-ginger syrup.
- Shake with Ice: Fill the shaker with ice and shake vigorously for about 10–15 seconds to chill and blend the ingredients.
- Strain and Serve: Strain the mixture into a rocks glass filled with fresh ice.
- Float the Islay Scotch: Slowly pour the Islay Scotch over the back of a bar spoon so it floats on top of the drink, adding a smoky layer to the cocktail.
- Garnish: Garnish with a lemon wheel or a piece of candied ginger for a touch of visual appeal and extra flavor.
Tip: The smoky Scotch float adds an aromatic, smoky finish, so choose an Islay Scotch that has a robust, peaty flavor.
Choosing the Right Ingredients
- Blended Scotch: A smooth, versatile blended Scotch forms the base of the Penicillin. Look for a Scotch that’s well-balanced and not overly smoky, such as Monkey Shoulder or Dewar’s.
- Islay Scotch: The Islay Scotch float is essential for adding that signature smokiness. A small amount of Laphroaig or Ardbeg works perfectly, bringing a peaty, smoky layer that complements the ginger and honey.
- Honey-Ginger Syrup: This homemade syrup is key to achieving the right balance of sweetness and spice. Fresh ginger provides a zesty kick that pairs well with the smoky Scotch.
- Lemon Juice: Fresh lemon juice adds brightness and acidity, balancing the sweetness of the honey-ginger syrup and the richness of the Scotch.
- Garnish: A lemon wheel or a piece of candied ginger adds a touch of elegance and enhances the drink’s presentation.
Tips for Perfecting Your Penicillin Cocktail
- Use Fresh Ingredients: Fresh lemon juice and homemade honey-ginger syrup make a big difference, providing vibrant flavors that enhance the cocktail’s overall balance.
- Float the Islay Scotch Carefully: Pour the Islay Scotch slowly over a spoon to create a clean float. This technique ensures the smoky Scotch remains as an aromatic layer on top of the drink.
- Experiment with Garnishes: A lemon wheel is classic, but candied ginger or a small piece of fresh ginger root can add a unique twist.
- Serve Over Fresh Ice: Using fresh ice keeps the drink cold without overly diluting it, allowing you to enjoy each layer of flavor.
Penicillin Variations to Try
While the classic Penicillin is delightful as is, here are a few variations to explore:
- Hot Penicillin: Serve the drink warm by omitting the ice and gently warming the ingredients (except the Islay Scotch) before pouring into a mug. Add the Islay float on top for a cozy winter version.
- Penicillin Sour: Add an egg white to the shaker for a frothy, creamy version that mellows out the flavors and creates a smooth texture.
- Spicy Penicillin: Add a few slices of fresh jalapeño to the shaker for a spicy twist that enhances the ginger’s natural heat.
- Herbal Penicillin: Muddle fresh herbs like rosemary or thyme with the honey-ginger syrup for an herbal variation that adds a touch of green flavor.
- Citrus Penicillin: Substitute some of the lemon juice with fresh orange or grapefruit juice for a citrus-forward variation that complements the smoky Scotch.
