Sweet, smoky and with a good kick of ginger, this is a cocktail to savour.

About the cocktail

‘Sugar… Oh, honey honey…’ As far as we’re concerned, The Archies could very well be singing about just how sweet a dash of honey can be in any classic cocktail. Next on our playlist? We’re glad you asked. “Siri, play ‘Smoke on the Water’”, and with some help from Deep Purple, we’ve set the scene for this sweet and smoky cocktail concoction: the Penicillin. 

A homage to classic cocktails like the Whiskey SourHot Toddy and Gold Rush, Australian bartender Sam Ross fashioned the Penicillin in the early 2000s at New York’s pioneering mixology bar Milk & Honey. Elevating the time-honoured ingredients of ginger, lemon and honey, Sam skipped the bourbon, opting instead for a blended Scotch, flipping the switch with his modern smoky take. 

Sitting atop all that syrupy sweetness and zesty lemon, the pivot to peaty Scotch is the masterstroke in this delicious drink. The piece de resistance, if you will. The balance of smokiness from the Scotch float adds a wave of aromatics from the outset; each sip reveals a captivating medley of sour, bitter and sweet. 

A formidable spirit in its own right, Scotch isn’t seen in cocktails as often as its generally tamer counterparts –  its smokiness can be a wee bit intense. Yet that’s precisely why the Penicillin is a force to be reckoned with, and why you should add it to your cocktail repertoire.

Ingredients

  • 10mL honey water (see method)
  • 45mL blended Scotch whisky
  • 20mL fresh lemon juice
  • 15mL good quality ginger syrup
  • 10mL peated Scotch whisky (to float)
  • Garnish: skewered candied ginger

Method

  1. Mix 2 parts honey with 1 part water in a pot and bring to a boil. When emulsified, reduce the heat and simmer for 5 minutes. Store in the fridge to allow the syrup to cool
  2. Pour the blended Scotch, lemon juice, honey water and ginger syrup into a shaker
  3. Add ice to the shaker ensuring the larger side is secured over the smaller side
  4. Turn the shaker over so small tin is facing the roof and shake until the outside is frosty – approximately 10 seconds
  5. Tap where the tins meet to release the airlock (you will hear a slight pop)
  6. Strain the cocktail carefully into a rocks glass over ice
  7. Float peated Scotch whiskey on top by pouring it gently over the back of a barspoon or tablespoon
  8. Garnish with skewered candied ginger

Dan’s top tips

Ginger and extra-smoky Scotch lend complexity to this modern riff on a Whiskey Sour, and while we love Sam’s version, after you’ve mastered it, why not shake things up a little? 

Other bartenders have adapted Sam’s formula with gin and even rum. But our favourite remix has to be the Penicillin Margarita, which features smoky tequila, fresh muddled ginger and a dash of lime juice for an added kick.

You can even turn up the volume by swapping the tequila and Scotch base out for the agave-based smoky spirit, mezcal. Offering complex charms and artisanal aesthetics, mezcal is a match made in heaven with citrusy bevs. It works beautifully with the Penicillin, maintaining its smoky signature scent and soothing honey and ginger hit. Music to our ears.
