A Modern Classic with Old-School Roots

In the world of cocktails, true modern classics are rare. But the Penicillin Cocktail, created in the early 2000s by Melbourne-born bartender Sam Ross at Milk & Honey in New York, has earned its spot.

Ross blended elements of whisky sours with medicinal-style hot toddies, combining:

Blended Scotch whisky for smoothness,
Islay whisky for a smoky float,
Honey-ginger syrup for sweetness and spice,
Fresh lemon juice for acidity and balance.

The playful name “Penicillin” hints at its soothing qualities — a cocktail that feels like both a cure and a comfort.

Why the Penicillin Works

The genius of this drink lies in its balance of contrasts:

Sweet vs. spicy (honey and ginger),
Smooth vs. smoky (blended Scotch and Islay float),
Rich vs. fresh (syrup and citrus).

Each sip evolves: you start with zesty lemon, move into warming ginger-honey sweetness, and finish with smoky whispers of Islay peat.

Penicillin Cocktail Recipe (Australian Measurements)

Ingredients:

60 mL blended Scotch whisky (Monkey Shoulder, Chivas Regal)
20 mL freshly squeezed lemon juice
20 mL honey-ginger syrup (recipe below)
7 mL peated Islay whisky (Laphroaig, Ardbeg)
Ice
Candied ginger or lemon twist, for garnish

Honey-Ginger Syrup:

½ cup honey
½ cup water
2 tbsp freshly grated ginger

Method: Combine honey and water over medium heat until dissolved. Add ginger, simmer 5–10 minutes, steep 10 more, strain, and cool.

Shaking the Cocktail:

Chill a rocks glass.
In a shaker, combine blended Scotch, lemon juice, and syrup with ice.
Shake vigorously 10–15 seconds.
Strain over fresh ice in the glass.
Float the peated whisky by slowly pouring over the back of a spoon.
Garnish with candied ginger or lemon.

Variations & Personalisation

Whisky swaps: Try Irish whiskey for a lighter base or bourbon for richer sweetness.
Fruit additions: Muddle pineapple or add orange bitters for a tropical edge.
Herbal twists: Shake with rosemary or garnish with charred lemon for aromatics.
Spicy kicks: Use chili-infused honey or extra ginger for more zing.

Food Pairings

Smoked salmon bites → mirrors the whisky smoke.
Chargrilled lamb skewers → play into honey-ginger warmth.
Creamy cheeses → brie or camembert contrast the acidity.
Dark chocolate with ginger → indulgent dessert pairing.

FAQs

Is the Penicillin really medicinal?
Not officially — but honey, ginger, and lemon are known to soothe colds, and whisky certainly helps you relax.

Do I have to float the Islay whisky?
Yes for presentation and layered flavour, but you can also stir it in if you prefer a blended profile.

Can I batch this cocktail?
Yes. Pre-mix the blended Scotch, syrup, and lemon juice in a jug. Shake each serve fresh with ice and float the peated whisky individually.
