To make a tequila old fashioned, stir 2 ounces of reposado tequila with a quarter ounce of agave syrup and two to three dashes of aromatic bitters over a large ice cube, then express an orange peel over the top. Reposado is the best choice because its light oak and vanilla stand in for the barrel character of whiskey, making this the ideal cocktail for converting a bourbon drinker to agave. It is spirit-forward, simple, and endlessly adjustable.
The old fashioned is the original cocktail, in the most literal sense: when the word "cocktail" was first defined in the early 1800s, it meant spirit, sugar, water, and bitters, which is exactly this drink. Swapping whiskey for reposado does not break the formula. It reveals a new side of it. I built my first one for a whiskey-loyal guest who swore tequila was for margaritas. Two sips in, he asked for the recipe.
Why Reposado Is the Right Pour?
The old fashioned was designed to showcase an aged, barrel-touched spirit, which is exactly what reposado is. Rested two to twelve months in oak, a good reposado carries the vanilla, light caramel, and gentle spice that the cocktail's sugar and bitters are built to frame. A blanco can work for a brighter, more agave-forward version, but it lacks the wood that gives the drink its familiar backbone. An añejo works too, though its deeper oak can tip the balance toward a whiskey impression and mute the agave. Reposado sits in the sweet spot: enough barrel to feel like an old fashioned, enough agave to remind you it is not whiskey.

The Recipe
Here is the build I use at home. It scales cleanly and rewards good ice.
Ingredients for a tequila old fashioned: reposado, agave syrup, bitters, and orange peel
Combine 2 ounces of reposado tequila, a quarter ounce of agave syrup, and two to three dashes of aromatic or mole bitters in a mixing glass with ice. Stir for about thirty seconds, until cold and slightly diluted. Strain over one large ice cube in a rocks glass. Express an orange peel over the surface by pinching it skin-side down to release the oils, then drop it in. That is the whole drink. The stir, not a shake, keeps it clear and silky, and the single large cube melts slowly so it never turns watery.

Bitters and Sweetener Choices
Small choices define this cocktail. On sweetener, agave syrup is the natural partner, since it comes from the same plant and dissolves without the graininess of a raw sugar cube. A light demerara or simple syrup also works and pushes the drink slightly richer and rounder. Go easy either way, because an over-sweetened old fashioned buries the spirit. On bitters, classic aromatic bitters keep the drink traditional, while mole bitters, with their cocoa and chile notes, lean into the tequila's Mexican roots and are my preferred touch. Orange bitters brighten it further. Start with a quarter ounce of sweetener and two dashes of bitters, taste, and adjust from there. The drink should taste of tequila first, with sweetness and spice in support.
Common Mistakes to Avoid
A few errors turn a great old fashioned into a mediocre one. The most common is over-dilution from small, fast-melting ice, so use one large cube or sphere instead of a handful of cubes. The second is over-sweetening, which smothers the agave; when in doubt, use less syrup. The third is skipping the orange peel express, which is not just a garnish but a real flavor step, since the citrus oil sprayed across the surface is half the aroma. The fourth is shaking instead of stirring, which clouds the drink and adds too much air. And the fifth is reaching for a harsh, bottom-shelf tequila, since a spirit-forward cocktail hides nothing. Use a tequila you would happily sip on its own.
A Note From the Founder
"An old fashioned is the honest test of a spirit, because there is almost nothing to hide behind. Three ingredients and ice. When someone who only drinks bourbon takes a sip of a reposado old fashioned and pauses, that pause is the whole point. The cocktail did not trick them. It just let the agave speak in a language they already understood." Candice Wagner, Founder of El Cientelleo Tequila

Frequently Asked Questions
How do you make a tequila old fashioned?
Stir 2 ounces of reposado tequila with a quarter ounce of agave syrup and two to three dashes of aromatic or mole bitters over ice for about thirty seconds, then strain over one large ice cube in a rocks glass. Express an orange peel over the top and drop it in. Stir rather than shake to keep the drink clear and silky.
What is the best tequila for an old fashioned?
A reposado is the best choice, because its light oak and vanilla from two to twelve months in barrel frame the cocktail the way whiskey does, while keeping the agave present. Use a tequila good enough to sip neat, since a spirit-forward drink exposes any harshness. Añejo also works but leans more whiskey-like.
Can you use blanco tequila in an old fashioned?
Yes, for a brighter, more agave-forward version. A blanco old fashioned trades the oak and vanilla for citrus and pepper, which some drinkers prefer. It is a lighter, fresher take. For the classic barrel-driven character most people expect from an old fashioned, though, reposado is the better fit.
What sweetener goes in a tequila old fashioned?
Agave syrup is the natural choice, since it comes from the same plant as the tequila and dissolves cleanly. Light demerara or simple syrup also works and makes the drink slightly richer. Use about a quarter ounce and adjust to taste, keeping it restrained so the sweetness supports the spirit rather than covering it.
Why is it called an old fashioned?
The name comes from the drink itself being the original "cocktail." When the term was first defined in the early 1800s, a cocktail meant spirit, sugar, water, and bitters. As fancier mixed drinks appeared later in the century, drinkers who wanted the original asked for it made the "old-fashioned" way, and the name stuck.
