Tequila Sour Recipe: A Dry Reposado Sour With the Right Ratio

A tequila sour recipe is simple: shake tequila, fresh citrus, and a little sweetener, then add bitters and optional egg white for foam. Use reposado, lemon, lime, and a restrained amount of agave syrup. It is sharper and less orange-led than a margarita, which is exactly the point.

This is the drink to make when a margarita feels too familiar but you still want tequila and fresh citrus. It has the same basic family resemblance, then takes a turn toward bitters, texture, and a drier finish. No bottled sour mix. That stuff has had enough screen time.

What is a tequila sour?

A tequila sour is a shaken cocktail built from tequila, citrus, and sweetener. Most versions also use bitters, and many add egg white for a soft cap of foam. Think of it as a sour cocktail with tequila in the lead, not as a margarita wearing a different hat.

The important distinction is balance. A margarita usually leans on orange liqueur and often gets a salt rim. A tequila sour relies on fresh acid and a small amount of syrup, with bitters doing some of the work that orange liqueur would do in a margarita.

That is why a tequila sour can feel more direct. The tequila has more room. The citrus has edges. The drink does not need to taste like candy to be friendly.

Tequila sour ingredients and the right ratio

This is a single, up-style drink. Chill a coupe first, or use a small rocks glass over fresh ice if that is more your speed.

• 2 ounces reposado tequila
• 3/4 ounce fresh lemon juice
• 1/2 ounce fresh lime juice
• 1/2 ounce agave syrup (one part agave nectar, one part warm water)
• 2 dashes aromatic bitters
• 1 pasteurized egg white, optional
• Lemon peel or lime wheel, for garnish

That is the ratio: two parts tequila, one and one-quarter parts fresh citrus, and one-half part syrup. The lemon gives the drink its clear sour shape. The lime keeps it tied to tequila. The agave syrup rounds off the corners without taking over the room.

Use fresh juice. This is not a moral stance. Bottled lemon juice just has a different, flatter taste, and a drink with six ingredients has nowhere to hide it.

If you like a sweeter drink, move the syrup to 3/4 ounce. Do not add more juice first. If you want it drier, keep the citrus where it is and reduce the syrup to 3/8 ounce. Small changes matter here.

How do you make a tequila sour?

The full version uses two shakes. The first has no ice. The second gets the drink cold and adds dilution.

1. Add the tequila, lemon juice, lime juice, agave syrup, bitters, and optional pasteurized egg white to a shaker. 2. Seal it and shake hard without ice for 15 seconds. This is the dry shake. It starts building the foam before melting ice can thin it out. 3. Add a generous scoop of ice and shake again for 10 to 15 seconds, until the tin is very cold. 4. Fine-strain into the chilled coupe. Garnish with a lemon peel or a thin lime wheel.

If you skip the egg white, skip the dry shake too. Shake the remaining ingredients once with ice, strain, and drink. The result is still a proper tequila sour. It is simply leaner, brighter, and free of the foam.

There is no need to overwork the garnish. A citrus peel does the job. A cocktail should not need a small fruit salad to prove it is finished.

Does a tequila sour need egg white?

No. Egg white changes texture, not the core flavor. It gives the drink a soft foam and takes a little of the hard edge off the citrus. Leave it out if you do not want it, and the tequila sour without egg white will still taste balanced.

If you use it, choose pasteurized egg white or a pasteurized egg product. The FDA recommends pasteurized eggs or egg products for recipes served raw or undercooked, including egg-fortified beverages. Read its egg-safety guidance if you are serving drinks with raw egg components.

Aquafaba, the liquid from a can of chickpeas, is the easiest non-egg substitute. Use 1/2 ounce, then follow the same dry-shake and ice-shake method. It makes foam without adding a chickpea flavor once the drink is cold and citrusy.

The practical call is simple. Use egg white or aquafaba when you want a softer, more visual drink. Skip both when you want the tequila and citrus to stay sharp. Neither version is more serious. It is your glass.

What is the difference between a tequila sour and a margarita?

They share tequila and citrus, but they are not the same drink.

A classic margarita is tequila, lime, and orange liqueur, often with salt. It is built around lime and orange, and the salt can make the fruit taste louder. A tequila sour uses lemon and lime, a small amount of agave syrup, and bitters. Add foam and it has a different texture too.

The tequila sour is usually served up in a coupe. A margarita is more often served over ice or up with a salted rim. Those are conventions, not laws, but they point to the drinks' different moods.

If you want a crisp three-part tequila drink with a salt edge, make a classic margarita. If you want citrus, bitters, and a drink that lets a reposado show up, make this.

What tequila is best for a tequila sour?

Reposado is the best place to start. A little barrel character gives the bitters something to talk to, while the agave still stays present against the lemon and lime. You want a tequila with enough body to stand up to the citrus, not a bottle that disappears after the first shake.

Blanco works too. It makes a brighter, more peppery tequila sour, especially if you keep the egg white out. Use blanco when you want the drink to land closer to a lime-forward sour. Use reposado when you want a rounder middle and a little more oak in the finish.

If you are still sorting out those categories, start with what reposado means. For a more spirit-forward reposado drink, the tequila Old Fashioned takes the citrus down and lets the barrel speak more clearly.

Copal 22's three months in repurposed American whiskey barrels make it a natural reposado choice here. The oak and vanilla sit well with aromatic bitters, while the citrus keeps the drink from getting heavy.

Two tequila sour variations worth making

The no-egg tequila sour

Use the base recipe without egg white. Shake with ice and strain over one large cube in a rocks glass. This is the fastest version and the one to make when you want a clean, tart drink before dinner.

The chile-salt tequila sour

Make the egg-free version, then give half the rim a light coat of chile-lime salt. Keep the other half bare. You get the margarita nod without turning the whole drink into one.

Do not add orange liqueur to either version unless you are trying to make a margarita. At that point, just make the margarita. There is nothing wrong with a classic. There is also no need to call every tequila-and-citrus drink one.

The takeaway

The best tequila sour is not complicated. Start with reposado, use fresh lemon and lime, keep the syrup measured, and decide whether foam belongs in your glass. The drink should be tart, cold, and clearly tequila-first.

That is the whole job. Shake it hard, strain it clean, and leave the sour mix on the shelf.
