About this drink
The Penicillin was created by Sam Ross at Milk & Honey in New York around 2005 as a modern tribute to the whisky sour family. It pairs a smooth blended Scotch with a dram of smoky Islay whisky floated on top, giving the aroma its signature breath of peat and smoke. Ginger and honey syrups bring both warmth and sweetness, while lemon keeps it all fresh and sharp.
Questions and answers
Why two kinds of Scotch whisky in a Penicillin?
The blended Scotch forms the drink's base, while a thin layer of smoky Islay whisky on top gives a final, intense touch of smoke to every sip without dominating the whole drink.
Can you leave out the Islay float in a Penicillin?
You can, but the smoke is a large part of what makes the Penicillin the modern classic it is. Even a small amount makes a marked difference.
