Rosemary Old Fashioned: An Herbal Variation Recipe

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.

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.

Best Bourbon for Rosemary Old Fashioned

Rosemary's pine-and-resin character wants a bourbon that leads with vanilla, soft caramel, and rounded sweetness — not a high-rye, pepper-forward profile that would clash with the herb. Wheated bourbons (no rye in the mash bill) and well-aged corn-forward bourbons shine here. The demerara syrup adds caramel weight, so the bourbon needs enough backbone — 90 to 100 proof is the sweet spot — to hold its own against the syrup and the torched garnish.

Budget Picks (Under $30)

• Buffalo Trace (~$25) — The default for a reason: classic vanilla and caramel, soft mouthfeel, no rough edges. Lets the rosemary aromatic do the work without fighting it.
• Maker's Mark (~$28) — The original wheated mash bill: soft vanilla, light red-fruit, no rye bite. Easy on the herb and broadly available — a safe brand-name gateway.
• Larceny Small Batch (~$25) — Wheated, so no rye spice to clash with the herb. Soft vanilla and toffee; especially good with the honey and maple variations.
• Evan Williams Bottled-in-Bond (~$18) — A hundred proof at the lowest price on this page. Vanilla-forward with light spice and surprising depth for the money.

Mid-Range Picks ($30–$50)

• Maker's Mark 46 (~$38) — Wheated bourbon finished with French oak staves: extra vanilla and warm spice-cake notes that pair beautifully with rosemary's pine. The mid-range workhorse for this drink.
• Four Roses Single Barrel (~$45) — Silky, ripe fruit and baking spice; 50% ABV carries the herbal lift cleanly.
• Wild Turkey 101 (~$32) — Robust honey and vanilla with enough proof to stand up to the demerara and bitters. A reliable host bourbon — generous flavor, never fussy.

Premium Picks ($50+)

• Weller Special Reserve (~$50 SRP, often allocated above) — The wheated classic worth the hunt. Almost custard-like vanilla; rosemary on top reads like a perfect aromatic herb on perfect crème brûlée.
• Eagle Rare 10 Year (~$45–$55 retail) — Refined caramel and vanilla with the depth of age. The "impress guests on steak night" pick the recipe mentions in step 9.
• Knob Creek 12 Year (~$60) — Bonded backbone with a dozen years of barrel time: oak, vanilla, dark dried fruit. For a more savory-leaning Rosemary Old Fashioned.

Pricing reflects typical retail. Allocated bottles (Weller, Eagle Rare) often sell above MSRP at secondary markets — buy at the shelf when you see them.
