Best Tequila for Margaritas in the UK: 3 Styles Compared

The best tequila starting point for a classic Margarita is a blanco labelled 100% agave. For a current UK comparison, start with Olmeca Altos Plata for a bright citrus-led route or Espolòn Blanco for a producer-described pepper note. Choose Olmeca Altos Reposado only when you deliberately want a richer oak variation rather than the classic blanco reference.

Research checked 22 September 2026. We compared the official Margarita specification with current producer pages. We did not receive the bottles for coverage or run a blind tasting, so producer flavour descriptions are identified as such and there is no unsupported winner. This page owns the drink-style and recipe choice; our separate dated UK budget tequila comparison owns changing bottle prices.

Three tequila routes to compare for a Margarita

The first two are the like-for-like classic comparison. Reposado changes the style of the drink and should not be treated as an automatic upgrade. The matcher above turns those three routes into an exact bottle search while keeping current price, stock, seller and delivery with the retailer.

The recognised Margarita reference

The International Bartenders Association currently specifies 50ml 100% agave tequila, 20ml triple sec and 15ml fresh lime juice, shaken with ice and strained into a chilled glass, with an optional half salt rim. That is the reference point we use before changing sweetness or acidity.

The second and third rows are variations, not the IBA specification. Lime acidity changes by fruit, so a fixed recipe still needs a final taste.

Which is best for your Margarita?

Choose blanco for the classic answer

Blanco is the cleanest way to compare the balance of tequila, orange liqueur and lime because maturation is not adding an obvious oak direction. That does not make every blanco identical or mean that clear colour proves quality. It means the style is the most direct match for the official recipe.

Altos Plata and Espolòn Blanco are useful comparison points because both producers publish the 100% agave basis and describe the bottles clearly. Start with the same 50:20:15 recipe for each rather than changing the bottle, lime and orange liqueur at once. A controlled recipe makes the bottle comparison more meaningful.

Choose reposado for a deliberate richer variation

Reposado introduces a maturation influence. Altos describes its Reposado using cooked agave, orange, toasted-nut and woody language, so it is the relevant route when those are the qualities you actively want. It is not the default answer for someone simply asking for a classic Margarita.

Use the same measured reference first. If the result feels too rich or sweet, reduce syrup or return to blanco before increasing lime aggressively. Changing one variable at a time is more useful than assuming a more expensive or darker bottle must need a completely different recipe.

What “100% agave” does and does not mean

It is a production statement: the fermentable sugars come from blue Weber agave. Tequila without that statement may use other permitted sugars within the category rules. The statement does not prove a bottle is artisanal, additive-free, healthier or automatically smoother. It is useful because it narrows a crowded budget shelf using something more meaningful than bottle colour.

Do not repeat the old claim that mixto tequila is guaranteed to cause a worse hangover. Alcohol dose, pace, food, hydration and individual circumstances matter; a production category is not a health promise.

Blanco, reposado or gold?

• Blanco/plata: the default for a bright classic Margarita. It makes it easier to judge the balance between agave, orange and lime.
• Reposado: oak-rested, adding vanilla and spice. It can work in a richer Margarita or a Tommy's, but it is not required.
• Gold/joven: a category description, not a quality ladder. Read the agave statement and producer information instead of buying by colour.

How ABV affects the finished drink

A shaken Margarita is diluted by melting ice. A 40% tequila can remain more obvious after shaking than a 35–38% bottle, but strength alone does not determine flavour or quality. If the tequila disappears, first check whether the drink contains too much orange liqueur, syrup or meltwater. Buying a stronger bottle is not the only fix.

The exact strength can differ by market and listing. Altos currently publishes nutritional information for both 38% and 40% variants, which is a good reason to read the bottle being delivered rather than copying an ABV from an overseas article.

The five checks to make in a UK shop

1. Confirm the bottle says tequila and, for this use, 100% agave.
2. Check blanco/plata versus reposado rather than relying on clear or gold glass.
3. Read the labelled ABV on the exact UK bottle instead of assuming every market sells the same version.
4. Compare 70cl-equivalent delivered price; a cheaper 50cl bottle can cost more per serve.
5. Separate a normal price from a loyalty or limited promotion and verify whether the seller is the retailer or a marketplace merchant.

How much tequila do you need?

At the official 50ml measure, a 70cl bottle contains fourteen full tequila measures before spills. Four Margaritas need 200ml; eight need 400ml; twelve need 600ml. That leaves enough headroom in one 70cl bottle for twelve measured drinks, but not for fourteen if free-pouring or breakage is likely.

Shake individual or small measured batches rather than filling a household blender with ice and assuming the same dilution. For a party, pre-measure the liquid cold, then shake portions with ice immediately before serving.

Salt, ice and orange liqueur

Use a half salt rim so each sip can be tasted with or without salt. Chill the glass and shake with enough hard ice to cool the drink quickly. Cointreau is one triple-sec option, but the category contains products at different strengths and sweetness levels. If changing orange liqueur, hold the tequila and lime steady, then adjust one variable at a time.

Troubleshooting

• Too sour: add 5ml agave syrup or reduce lime next round; do not double the triple sec immediately.
• Too sweet: remove syrup, check the orange liqueur measure and use only a half salt rim.
• Watery: use colder glassware, enough ice and a firm 10–12 second shake rather than a long weak shake.
• Tequila disappears: reduce sweetener or orange liqueur before upgrading the bottle.

Frequently Asked Questions

Is blanco or reposado better for a Margarita?

Blanco is the clearest reference for a classic Margarita. Reposado is a deliberate variation when you specifically want a richer, oak-influenced direction.

Must Margarita tequila be 100% agave?

No law of cocktail making requires it, but the statement is a useful production filter and is part of the current IBA specification.

How many Margaritas come from 70cl?

At 50ml tequila per drink, a 70cl bottle contains fourteen measures before spillage.

Should a Margarita contain sugar syrup?

The IBA reference does not. Add a small measured amount only when your lime and orange liqueur leave the drink unbalanced.

Is gold tequila better than silver tequila for Margaritas?

No. Gold colour is not a simple quality grade. Check whether the bottle is blanco, reposado or another style and read the 100% agave statement and producer information.

Which UK tequila is best value for Margaritas?

Value changes with promotions, bottle size, ABV, seller and delivery. Use the separate dated budget comparison for current price evidence; use this page to choose the drink style first.

Alcohol is not risk-free. UK guidance advises adults not to regularly exceed 14 units a week and to spread that amount over three or more days. Do not drink and drive; if you are pregnant or think you could become pregnant, the safest approach is not to drink alcohol.
