Building on a classic whiskey sour recipe, the old thyme sour adds a number of new twists to create a delightful, very fun cocktail. The cocktail was created by Michael Grissinger and is innovative on many levels. It all begins with a mix of fresh thyme and Chartreuse, which is eventually lit on fire to give the drink a sweet and herbal smoky background.

Building on that, this sour combines Irish whiskey with elderflower and homemade cinnamon-thyme syrup. Of course, in true sour fashion, there's a healthy dose of fresh lemon and a touch of egg white for that amazing texture that no other ingredient can give drinks.


For the Cinnamon-Thyme Syrup:

  • 1 cup water

  • 1 1/2 cups sugar

  • 1 cinnamon stick

  • 2 sprigs fresh thyme

For the Cocktail:

  • 5 sprigs fresh thyme, divided

  • 1/4 ounce Green Chartreuse Liqueur

  • 2 ounces Irish whiskey

  • 1/2 ounce elderflower liqueur

  • 1 ounce freshly squeezed lemon juice

  • 1/2 ounce cinnamon-thyme simple syrup

  • 1 large egg white

  • 1 dash bitters

  • 1/2 teaspoon lemon zest

  • Lemon slice, for garnish

Steps to Make It

Make the Cinnamon-Thyme Simple Syrup

  1. Gather the ingredients.

  2. In a saucepan, bring the water to a boil and stir in the sugar to dissolve.

  3. Reduce the heat and simmer, stirring occasionally. Add the cinnamon stick and thyme and then simmer for about 20 to 30 minutes, to taste.

  4. Strain, cool, and bottle in a well-sealed container.

Make the Old Thyme Sour Cocktail

  1. Gather the ingredients.

  2. Place the 2 sprigs of thyme and Chartreuse in an old-fashioned glass and stir to coat the thyme. Set aside.

  3. In a cocktail shaker, add 2 sprigs of thyme, whiskey, elderflower liqueur, lemon juice, cinnamon-thyme syrup, egg white, and bitters.

  4. Dry shake to incorporate the ingredients, then add ice and shake thoroughly.

  5. Light the liqueur-soaked thyme on fire in the glass.

  6. Double strain the contents of the shaker into the glass to extinguish the flame.

  7. Add lemon zest and fill with fresh ice.

  8. Garnish with a lemon slice and the remaining sprig of thyme. Serve and enjoy.

Raw Egg Warning

Consuming raw and lightly cooked eggs poses a risk for foodborne illness.


  • The flavored syrup makes just over 1 cup, so you'll have plenty for many cocktails. It can also be used in other mixed drinks and makes an interesting sweetener for tea.
  • Store the homemade syrup in the refrigerator for up to two weeks.
  • Green Chartreuse is higher proof (55 percent ABV) than Yellow Chartreuse (40 percent ABV), so it will burn better.
  • Skip the egg white if you prefer.

How Strong Is an Old Thyme Sour?

The old thyme sour is similar in strength to most sour cocktails. Its alcohol content should come out to around 18 percent ABV (36 proof), or about the same as a strong whiskey ginger.
