Introduction 🥃

The Penicillin cocktail isn't your grandmother's cough syrup (though it might just cure what's bothering you better than anything from her medicine cabinet). This modern classic combines the warming embrace of Scotch whisky with the zing of fresh ginger and lemon, topped off with a mysterious smoky float that'll make you forget all about your troubles.

Unlike its pharmaceutical namesake, this Penicillin won't require a prescription, though you might find yourself becoming dangerously addicted to its complex, soul-warming flavors.

A Shot of History 📜

This cocktail earned worldwide fame because it's brilliant in its simplicity and flavor. This liquid masterpiece was born in 2005 at the legendary Milk & Honey bar in New York City, created by the brilliant Australian bartender Sam Ross. Ross wasn't trying to reinvent the wheel; he was simply craving something that combined his love for Scotch with the comforting flavors of honey and ginger. The result was pure genius, a drink that bridges the gap between classic cocktail craftsmanship and modern innovation.

The name "Penicillin" was a perfect fit. It's a nod to the healing properties of the honey-ginger combo (a common home remedy for sore throats) and the fact that the smoky Scotch "infects" the entire drink with its deliciously peaty flavor. It spread through the cocktail world like a… well, like a good virus, quickly becoming a staple on craft cocktail menus worldwide.
