Discover The Effects Of Ageing On Mezcal
Mezcal is often celebrated for its raw, smoky complexity, but ageing introduces a whole new dimension to this already dynamic spirit. While most mezcals are enjoyed in their young, unaged form (joven), ageing can soften, deepen, and even transform its flavours - much like whiskey or rum.
But does ageing mezcal enhance it, or does it strip away the very essence that makes it unique? We will explore the different types of aged mezcal, how barrel ageing impacts flavour, and whether ageing is truly necessary for this artisanal spirit.
How Ageing Affects Mezcal’s Flavour
Ageing mezcal in barrels introduces three key transformations:
- Smoother Texture – The spirit mellows over time, reducing the bite of alcohol
- New Flavour Layers – Wood imparts notes of vanilla, caramel, spice, and nuttiness
- Less Smoke, More Sweetness – Barrel ageing can soften mezcal’s signature smoky edge, making it more accessible.
However, some purists argue that ageing masks the agave’s natural flavours, which are the heart and soul of mezcal. Let’s break down the different ageing categories and what they bring to the table.
The Different Categories Of Aged Mezcal
| Ageing Category | Time Aged | Flavour Characteristics |
|---|---|---|
| Joven (Young) | 0 - 2 months | Bright, smoky, earthy, with pure agave flavour |
| Reposado (Rested) | 2 - 12 months | Smooth, hints of vanilla, oak, and spice |
| Anejo (Aged) | 1 - 3 years | Rich, caramelised, nutty, with oak influence |
| Extra Anejo (Ultra-Aged) | 3+ years | Deep, whiskey-like, with dark chocolate and tobacco notes |
| En Barro (Clay-Aged) | Varies | Earthy, mineral-driven, softer texture |
Joven Mezcal (0 - 2 Months): The Purest Expression
Best for: Traditionalists and Mezcal purists,
- Bottled with little to no ageing, typically within 2 months of distillation
- Maintains the truest flavours of agave - smoky, earthy, herbal, and vegetal
- Often considered the best way to experience mezcal as intended by the mezcalero
Drink If You Love: Raw, bold flavours and want to taste the full character of the agave.
Reposado Mezcal (2 - 12 Months): Smooth And Balanced
Best for: Drinkers who enjoy a smoother sip with mild oak influence.
- Aged in wooden barrels (often oak) for 2 - 12 months
- Introduces notes of vanilla, caramel, and baking spices, while keeping some smoky character
- Ideal for those who find joven mezcals too aggressive but don’t want the deep oak influence of an anejo
Drink If You Love: Tequila reposado or lightly aged spirits like rum.
Anejo Mezcal (1 - 3 Years): Rich And Complex
Best for: Whiskey and Cognac lovers.
- Aged in barrels for 1 to 3 years, often in ex-bourbon or wine casks
- Gains flavours of toffee, nuts, dark chocolate, and tobacco, with a silky texture
- The longer ageing process diminishes the smoke and agave-forward notes, making it more whiskey-like
Drink If You Love: Bourbon, Scotch, or aged tequila anejo.
Extra Anejo Mezcal (3+ Years): Ultra-Aged And Deeply Flavoured
- Best for: Lovers of dark, aged spirits with layered complexity
- Aged 3 years or more, developing a rich, oak-heavy profile
- Flavours of molasses, dried fruit, espresso, and vanilla become dominant
- The agave character is almost completely transformed, making it feel more like a fine aged rum or brandy.
Drink If You Love: Cognac, sherry-aged whiskeys, or old-school rums.
En Barro Mezcal (Aged In Clay Pots): A Different Take On Ageing
Best for: Those who want a softer, earthier alternative to barrel-aged mezcal.
- Instead of ageing in oak, some mezcals are aged in clay pots, an ancient method used in some regions of Mexico
- Clay imparts mineral notes and enhances the spirit’s natural earthy characteristics
- Unlike oak barrels, which add sweetness, clay aging preserves mezcal’s raw and vegetal essence
Drink If You Love: Earthy, terroir-driven spirits with natural character.
Barrel Ageing: Does It Enhance Or Take Away From Mezcal?
While ageing adds complexity, some argue that it distorts mezcal’s true essence. Mezcal is traditionally appreciated for its raw agave flavours and smoky depth, both of which can be muted by time in wood.
Here’s how barrel ageing changes the profile:
| Characteristic | Joven | Aged Mezcals |
|---|---|---|
| Agave Flavour | Strong, vegetal, smoky | Softer, wood-forward |
| Smoke Level | Bold and noticeable | Mellowed by wood ageing |
| Sweetness | Natural agave sweetness | Enhanced by caramel/vanilla notes from oak |
| Complexity | Bright and sharp | Smooth and layered |
Which Mezcal Ageing Style Is Right For You?
Ultimately, the choice between joven and aged mezcal comes down to personal preference.
- Want the rawest, most traditional experience? Go for a joven
- Prefer a more refined, smoother sip? Try a reposado or anejo
- Like whiskey, brandy, or dark rum? Extra anejo might be for you

Final Thoughts: Should You Age Mezcal?
While ageing can enhance smoothness and complexity, it also alters mezcal’s raw and wild spirit. Some drinkers love the added depth of aged mezcal, while others prefer the purity of a freshly distilled joven.
No matter which style you prefer, one thing is clear: mezcal is an incredibly diverse spirit, capable of evolving in fascinating ways. Whether you sip it fresh or aged, take your time, savour the flavours, and appreciate the craftsmanship behind every bottle.
