Rosemary Old Fashioned: An Herbal Variation Recipe
Share
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.

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

Full guide →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.
Variations
Once you’ve nailed the classic rosemary build, these riffs change the accent while keeping the same method.
Rosemary-Honey
Swap half the demerara for honey syrup — rounder and richer, especially with a heavier bourbon.
Rosemary-Maple
Use maple syrup instead of demerara. With the pine of rosemary, it drinks like fall in a glass.
Rosemary-Smoke
Build standard, then briefly smoke with cherrywood for a savory, campfire edge under the herb.
Stock the bar with bourbon for herbal variations and rye for the original.
