What You'll Need Before You Buy Reposado Tequila
Learning how to choose a good reposado tequila UK shoppers can trust comes down to reading labels properly, not chasing the loudest bottle on the shelf. Reposado tequila is a 100% blue agave spirit rested in oak barrels for between two months and one year, which gives it the golden colour and softer mouthfeel that blanco lacks (crt.org.mx).
At Thiago Tequila, we source, distil and bottle in the highlands of Jalisco, so we spend a lot of time explaining what separates a genuine craft reposado from a flavoured spirit with a tequila label slapped on it. Below, we'll walk through six checks that take about two minutes in a shop or online, and the mistakes that catch most buyers out.
Before you start, have these to hand:
- A phone, to check the NOM number against the official tequila register
- The bottle itself, or a clear product photo if you're buying online
- A rough idea of whether you want to sip it neat or mix it
- A budget that reflects real agave, not syrup
Step 1: Read the Label for 100% Blue Agave and NOM Number
The single most useful label check is the phrase "100% Blue Agave" or "100% de Agave." If a bottle says only "tequila" or "mixto," it can legally contain up to 49% other sugars, usually cane or corn syrup. That is where the harsh burn and synthetic aftertaste come from.
Look for the NOM number too, printed as NOM followed by four digits. This is the distillery registration issued under Mexican tequila standards, and it tells you exactly which facility made the spirit.
Why the NOM Number Matters for Authenticity
A NOM number is your proof that the liquid was actually distilled at a registered tequila facility in one of Mexico's permitted regions, rather than blended elsewhere and labelled loosely. You can check any NOM against the Consejo Regulador del Tequila producer register, the body that oversees tequila production standards.
Two bottles can share a NOM number and still taste completely different, because the same distillery often produces several brands. What the number confirms is provenance, and provenance is the difference between a rested agave spirit and a sweetened imitation.
Step 2: Understand the Ageing Process and Flavour Profile
Ageing length determines almost everything about how a reposado tastes, but the barrel itself matters just as much as the clock. The legal minimum for reposado is two months in oak, and the maximum is just under a year, which is why the category spans everything from lightly rested to deeply rounded.
Flavour builds in layers as the spirit sits in the barrel. Early months bring citrus notes and a peppery finish from the agave itself. Longer resting adds caramel undertones, vanilla notes and a rounder body, with tertiary flavours from the wood influence creeping in.
What most guides skip is the barrel itself. Most producers rest reposado in ex-bourbon American oak, which contributes vanilla, coconut and a soft sweetness. Some use French oak for a drier, spicier profile, and a smaller number use ex-wine or ex-sherry casks for dried-fruit character. The wood type, the toast level and whether the cask is first-fill or refill all shift the final flavour before a single drop is bottled.

Blanco vs. Reposado vs. Añejo: What Changes in the Barrel
Blanco is unaged or barely rested, bottled almost straight from distillation. Reposado sits in oak for two months to a year, softening the edges. Añejo rests one to three years, and extra añejo beyond that, picking up heavier wood character with each stage.
| Category | Ageing Time | Typical Flavour | Best For |
|---|---|---|---|
| Blanco | 0-2 months | Bright citrus, pepper | Margaritas, mixing |
| Reposado | 2-12 months | Caramel, vanilla, honey | Sipping or cocktails |
| Añejo | 1-3 years | Oak, dried fruit, spice | Slow sipping |
| Extra Añejo | 3+ years | Deep wood, rich sweetness | Special occasions |
Reposado is the sweet spot for most drinkers because it carries enough agave character to sip but enough smoothness to mix well.
The Additive Question: Why Barrel Age Alone Doesn't Guarantee Quality
Here is the angle most buying guides miss. A reposado can spend a full eleven months in oak and still taste flat, because tequila regulations permit a small list of additives, caramel colouring, glycerin, sugar syrup and oak extract, to be added after distillation without appearing on the front label. A producer can use these to fake the colour, body and sweetness that real barrel time would have delivered naturally.
That is why the ageing statement on the bottle is only half the story. A genuinely rested reposado should show its barrel character through aroma and mouthfeel, not just shade. If a pale-gold reposado tastes of thick vanilla syrup rather than layered caramel and agave, additives are usually doing the work.
At Thiago, our reposado rests six months in oak before any flavour is introduced, so the base spirit already carries the caramel and vanilla structure that real barrel time builds. You can see how that base performs across the range on our Thiago tequila collection.
Step 3: Check the ABV: Is Tequila 40 Percent ABV?
Yes, tequila is typically 40 percent ABV, which is the standard strength for most bottles sold in the UK. ABV stands for alcohol by volume, so a 40 percent bottle is 80 proof. Anything lower has usually been diluted or sweetened to mask a thin spirit.
Strength matters for two reasons. First, a full-strength spirit holds its flavour when you add ice or mixer, rather than turning watery after five minutes. Second, a 40 percent pour delivers real agave character in one or two drinks, so you are not drinking more just to taste it.
Check the ABV on the back label before you buy. Some flavoured products sit at 35 percent or lower, which usually signals added sugar or syrup doing the work that agave should be doing.
Step 4: Decide Between Sipping Neat and Reposado Tequila Cocktails
Your intended serve should shape the bottle you buy. A reposado with strong vanilla and caramel notes rewards slow sipping over ice, while a brighter, more citrus-forward one disappears into a mixer.
For sipping, pour 25ml into a tumbler with a single large cube and let it sit for a minute. The aroma opens up, and you'll notice the difference between a smooth reposado and one with a harsh finish almost immediately.
For cocktails, reposado tequila cocktails work best when the spirit can hold its own against other ingredients. Try a Paloma with fresh grapefruit, a Mexican Mule with ginger beer, or an Espresso Martini built on a coffee-infused reposado.
Step 5: Find the Best Flavoured Tequila UK Buyers Can Trust
Flavoured tequila is where most buyers get burned. The category is full of products built on syrup, which taste sweet on the first sip and cloying by the third, and leave a coating on your tongue that real agave never does.
The fix is to check what the flavour is built on. Genuine flavoured tequila starts with a 100% blue agave reposado and adds real ingredients after distillation. Look for "no added sugar" on the label, and be sceptical of any flavoured spirit that won't state its ABV clearly.
How to Verify a Flavoured Tequila Before You Buy
Run these four checks in order. They take under a minute and separate a real flavoured reposado from a sweetened imitation.
1. Confirm the base is 100% blue agave. The label must say "100% Blue Agave" or "100% de Agave," not just "tequila." A flavoured product built on mixto is already compromised before the flavour goes in.
2. Check the ABV. A genuine flavoured reposado holds 40% ABV. Anything at 35% or lower usually signals added sugar or water doing the work that agave and barrel time should be doing.
3. Look for named ingredients. Real fruit, vanilla bean, coffee or tamarind should appear by name. A catch-all "natural flavouring" with no detail is a warning sign, not a reassurance.
4. Check for a no-added-sugar claim. If the label is silent on sugar, assume there is some. A brand confident in its recipe will say so plainly.
What UK Labelling Law Actually Requires
Under UK food labelling rules, a pre-packaged alcoholic drink must declare its ABV and its ingredients, including any additives or flavourings used. What it does not require is a front-of-pack breakdown of how much sugar or syrup has been added, which is exactly why the gaps in a label tell you as much as the claims. The UK guidance on alcohol labelling and ABV declaration is worth reading if you want to understand what a producer is legally obliged to disclose.
This is the approach we take at Thiago. Our range starts with six-month rested Highland Blue Agave Reposado and adds real Mexican ingredients, never syrup. The Thiago Black Cherry Tequila is the clearest example: silky enough to drink straight, bold enough to carry a margarita, with zero added sugar at 40% ABV. If you want to taste the difference across flavours before committing to a full bottle, the Thiago minis bundle lets you compare them side by side.

Step 6: Try a Tequila Minis Bundle for Festivals and Travel
A tequila minis bundle solves a problem full-size bottles can't: drinking well when you're nowhere near a bar or a kitchen. At 50ml, minis are plane baggage friendly, fit in a jacket pocket, and let you sip, spritz or build a cocktail on the go.
For festival goers, that means no queuing at an overpriced bar and no warm, flat mixed drink in a plastic cup. For weekend breaks with friends, it means a proper drink on arrival without committing to a full bottle. For gifting, a three-pack lets someone try every flavour before buying a 70cl.
Our minis cover the full range: Black Cherry, Vanilla, Coffee and the limited-release Tamarindo Sour. Free delivery applies on mini packs, so trying all three is a low-risk way to find your favourite before sizing up.
Common Mistakes to Avoid When Choosing Reposado Tequila
The most common mistake is buying on price alone. Cheap "tequila" is usually mixto, and the saving shows up as burn and a sugary aftertaste. A bottle made from 100% blue agave costs more to produce, and you taste the difference in the first sip.
The second mistake is assuming darker means better. Colour comes from time in oak, but it also comes from added caramel colouring. A pale gold reposado can be every bit as good as a deep amber one, so judge by the label and the taste, not the shade.
The third is ignoring the finish. A good reposado leaves a clean, warm trail that fades rather than a sharp sting at the back of the throat. If the burn lingers, the spirit was likely rushed or sweetened to hide it.
The fourth is buying flavoured tequila without checking the sugar content. If the label won't say "no added sugar," assume there is some, and expect it to taste like it.
Frequently Asked Questions
What should I look for on a reposado tequila label?
Check for '100% Blue Weber Agave' rather than 'mixto', which signals added sugars. Look for the NOM number to verify the distillery, and check the ABV. A reposado tequila should state it is rested for at least two months. Additive-free claims matter too. If the label lists syrups or artificial flavourings, it is not a clean reposado.
Is tequila 40 percent ABV standard for reposado?
Yes, 40% ABV is the standard for most premium reposado tequilas. Some bottles range from 35% to 55%, but 40% ABV balances flavour and smoothness without a harsh burn. If you want a sipping tequila, look for 40% ABV. Anything lower may taste diluted, and anything higher can overwhelm the agave notes.
Are flavoured reposado tequilas considered authentic?
Flavoured reposado tequilas can be authentic if they use real ingredients rather than syrups. A reposado base aged in oak barrels still delivers caramel and vanilla notes. When natural fruit or botanical infusions are added after distillation, the spirit retains its agave character. Check for no added sugar and real ingredient sourcing to confirm quality.
How does the ageing process affect reposado tequila flavour?
Ageing in oak barrels for two months to one year gives reposado tequila its signature caramel, honey, and spice notes. The wood softens the agave's peppery edge and adds vanilla and citrus undertones. Longer ageing creates deeper tertiary flavours. A six-month rest, like Thiago uses, balances smoothness with a clear agave core.
Choosing well comes down to reading four things properly: the agave percentage, the NOM number, the ABV and the sugar claim. Get those right and you'll rarely buy a bottle you regret. At Thiago Tequila, every bottle starts with six-month rested Highland Blue Agave Reposado, real Mexican ingredients and zero added sugar, whether you're sipping it neat at home or packing the 50ml minis for a festival. Try all three minis for £15.99 and taste the difference for yourself.
