Key takeaways
- 1½ oz (45 ml) reposado tequila — 100% agave only
- ½ oz (15 ml) mezcal — espadín works for most bottles
- ¼ oz (7.5 ml) agave syrup, or 1 rich bar spoon (~5 ml) of agave nectar thinned 2:1 with hot water
- 2 dashes Angostura bitters (roughly ⅛ tsp total)
- Orange peel for garnish, expressed over the glass
- Ice: one large cube (2-inch) for serving, standard cubes for stirring
Oaxacan Old Fashioned Recipe: The Direct Formula
The standard Oaxacan Old Fashioned recipe is 1½ oz reposado tequila, ½ oz mezcal, ¼ oz agave syrup (or 1 bar spoon), and 2 dashes of Angostura bitters, stirred over ice and served in a rocks glass over one large cube with an expressed orange peel. That 3:1 tequila-to-mezcal split is the version bartender Phil Ward popularized at Death & Co. in New York in the late 2000s, and it remains the reference point every variation is measured against.
Ingredients and Exact Measurements
- 1½ oz (45 ml) reposado tequila — 100% agave only
- ½ oz (15 ml) mezcal — espadín works for most bottles
- ¼ oz (7.5 ml) agave syrup, or 1 rich bar spoon (~5 ml) of agave nectar thinned 2:1 with hot water
- 2 dashes Angostura bitters (roughly ⅛ tsp total)
- Orange peel for garnish, expressed over the glass
- Ice: one large cube (2-inch) for serving, standard cubes for stirring
Pure agave nectar straight from the bottle is thick enough to sink and pool at the bottom of a cold mixing glass. Thinning it 2:1 with hot water (two parts nectar to one part water) keeps the agave flavor while letting it integrate in under 20 seconds of stirring. Premixed agave syrup from brands like Monin or a homemade batch both work — just account for the water content if a recipe calls for nectar.

Choosing Your Tequila-to-Mezcal Ratio
The ratio is the single biggest dial on this drink. Mezcal’s smoke dominates fast, so small shifts matter more than they do in most stirred cocktails.
| Ratio (tequila : mezcal) | Tequila | Mezcal | Character | Best for |
|---|---|---|---|---|
| 4:1 | 2 oz | ½ oz | Faint smoke, tequila-forward | Mezcal skeptics, first try |
| 3:1 (classic) | 1½ oz | ½ oz | Balanced smoke and agave sweetness | The default serve |
| 2:1 | 1⅓ oz | ⅔ oz | Assertive smoke, drier impression | Mezcal fans, bold bottle pairings |
| 1:1 | 1 oz | 1 oz | Smoke-led, spirit-heavy | Smoky-islay-whisky drinkers only |
Blanco tequila makes a sharper, brighter drink; reposado adds vanilla and oak that softens the mezcal, which is why it’s the standard call. Avoid añejo — the heavy oak fights the smoke and the drink turns muddy.
Step-by-Step Method
- Chill the glass. Put a rocks glass in the freezer for 10 minutes, or fill it with ice while you stir.
- Combine in a mixing glass. Add tequila, mezcal, agave syrup, and bitters to a mixing glass or pint glass.
- Add ice and stir 25–30 seconds. You’re targeting roughly 20–25% dilution by volume — more on that below.
- Strain over a large cube. A single 2-inch cube melts far slower than cracked ice.
- Express the orange peel. Hold it skin-side down over the drink, pinch to spray the oils, rub the rim, drop it in or discard.
Dilution: The Part Most Recipes Skip
Stirring isn’t just about temperature — it adds water, and water is an ingredient. A 2-ounce pour of 80-proof spirit needs about ½ oz of melt water to open up. Here’s the math:
| Stir time | Melt water added | Drink temp | Result |
|---|---|---|---|
| 10 sec | ~0.15 oz | ~32°F | Hot, tight, ethanol bite |
| 20 sec | ~0.30 oz | ~28°F | Slightly under-diluted |
| 25–30 sec | ~0.45–0.55 oz | ~25°F | Target zone |
| 45+ sec | ~0.75 oz+ | ~23°F | Thin, washed out |
Fresh, cold ice dilutes faster than ice that’s been sitting wet, so adjust by a few seconds either way. Taste with a straw before straining if you’re unsure — the drink should taste integrated, not sharp.
Ice and Glassware Setup
Two different ice roles here: stirring ice and serving ice. For stirring, standard 1-inch cubes from a silicone tray work fine — surface area does the work. For serving, a single 2-inch cube or a clear ice sphere is worth the effort because its low surface-area-to-volume ratio keeps your second half of the drink from going watery. A 2-inch cube has roughly 40% less surface area per ounce of cooling than the same volume in small cubes.
Glassware: a double rocks glass (10–12 oz) gives the cube room and concentrates aroma better than a wide old fashioned glass. Weighted-bottom glasses feel better and keep the drink colder longer. If you don’t own a mixing glass, a pint glass plus a bar spoon and a small strainer cover the job — a $15 three-piece setup handles everything this recipe requires.
Common Mistakes and Fixes
- Too much agave. Agave nectar is about 1.5x sweeter than simple syrup. If the drink reads syrupy, cut to a scant bar spoon before reducing anything else.
- Overpowering mezcal. Bottles vary hugely in smoke intensity. A heavy-peat-style mezcal at ½ oz can taste like a 1:1 ratio; dial back to ⅓ oz and re-taste.
- Skipping the peel expression. The orange oils aren’t garnish decoration — they hit the nose first and soften perceived smoke. Express over the drink, not beside it.
- Shaking instead of stirring. This is a spirit-only cocktail; shaking adds air and chips ice, over-diluting and clouding the drink.
- Old ice. Ice absorbs freezer odors in 2–3 weeks. Fresh trays make a noticeable difference in a drink this spirit-forward.
FAQ
Can I use all mezcal instead of splitting the base?
Yes, but it stops being an Oaxacan Old Fashioned in the classic sense and becomes a mezcal old fashioned — a good drink, just smokier and less sweet-leaning. Keep the agave syrup at ¼ oz or drop it slightly.
What’s the best budget mezcal for this?
Espadín-based mezcals in the $30–45 range (brands like Vida or Montelobos) carry enough smoke without overwhelming the tequila. Spend your money on the mezcal rather than the tequila — it’s the flavor driver.
Can I batch this for a party?
Yes. Multiply everything by servings, pre-dilute by adding ~22% water by total volume (about 0.45 oz per drink), refrigerate, and pour over ice. Skip stirring entirely.
Mole bitters instead of Angostura?
It works — chocolate-forward bitters pair naturally with mezcal’s smoke. Use 2 dashes and expect a darker, more dessert-leaning profile.
