The Rosemary Old Fashioned is the herbal-savory variation that pairs especially well with steakhouse and fall-roast meals. Rosemary brings pine-and-resin notes that integrate with bourbon's vanilla and demerara's caramel, producing a more savory cocktail than fruit-based variations. Best built with a rosemary-infused syrup made in 15 minutes, garnished with a fresh sprig that's torched briefly to release oils.

Ingredients Makes 1
  • 2 oz
    Bourbon corn-forward bourbon plays well with rosemary
  • ¼ oz
    Rosemary syrup 1:1 demerara simmered with 3 fresh sprigs, 5 min
  • 2 dashes
    Angostura bitters
  • 1 swath
    Lemon peel lemon — rosemary plays brighter against lemon than orange
  • 1 large
    Ice rock single big piece only
  • 1 sprig
    Torched rosemary briefly torched 1–2 sec, rested across the rim
Method 6 steps
  1. 1

    Drop one large ice rock into a rocks glass.

  2. 2

    Add ¼ oz rosemary syrup and 2 dashes Angostura.

  3. 3

    Pour 2 oz bourbon over.

  4. 4

    Stir 25–30 times.

  5. 5

    Express a wide lemon peel; drop in.

  6. 6

    Briefly torch a rosemary sprig with a butane torch (1–2 seconds — until you smell the oils released); rest across the rim.

Pro Tip

Torch the rosemary garnish for 1-2 seconds with a butane torch — just until you smell it release. Don't set it on fire. The brief heat awakens the oils dramatically; raw rosemary smells flat by comparison. Hold the flame an inch away, not on the sprig.

Rosemary Syrup Recipe

Ingredients

  • 1 cup demerara sugar
  • 1 cup water
  • 3 fresh rosemary sprigs (about 5 inches each)

Steps

  1. Combine the demerara sugar and water in a saucepan and stir to combine.
  2. Add 3 sprigs of rosemary, about 5 inches each.
  3. Warm gently over medium heat, stirring as the sugar melts, and bring to a simmer.
  4. Simmer for 5 minutes, then turn off the heat.
  5. Cover and leave to steep for 30 minutes.
  6. Uncover, remove from the stove, and let it cool.
  7. Pour the syrup through a sieve.
  8. Store in the refrigerator for up to 2 weeks.
  9. Use about ¼ oz per cocktail — then go make a Rosemary Old Fashioned. Delicious, and perfect for impressing guests on steak night.

Why Bourbon and Lemon Peel

Rosemary's pine-resin character pairs better with bourbon's vanilla than rye's pepper. Lemon peel (instead of orange) brightens the herbal notes — orange goes muddy with rosemary. The torched rosemary garnish releases volatile oils that give the cocktail its dramatic aromatic.
