If you’ve ever ordered a margarita or browsed the spirits aisle, you’ve probably seen the words tequila, mezcal and agave used interchangeably.
But they’re not the same thing.
Understanding the difference can completely change how you choose spirits for cocktails — especially margaritas.
Here’s a simple guide to what each one means and how they’re used.
What Is Agave?
Agave is the plant used to make both tequila and mezcal.
It’s a large succulent native to Mexico that looks a bit like a giant aloe or spiky pineapple. The heart of the plant — called the piña — is harvested and cooked to extract sugars that can then be fermented and distilled into alcohol.
There are over 200 species of agave, but only certain types are used to produce spirits.
The most famous is blue agave, which is used to make tequila.
In short:
Agave = the plant
Tequila and mezcal = spirits made from that plant
Tequila is a type of agave spirit that must follow strict production rules.
To legally be called tequila, the spirit must:
• Be made from blue agave
• Be produced in specific regions of Mexico (mainly Jalisco)
• Follow regulated distillation processes
What Is Tequila?
Tequila is typically known for its clean, bright flavour, which makes it perfect for cocktails like margaritas.
There are several common styles:
Blanco – fresh, unaged tequila with crisp agave flavour
Reposado – aged in oak barrels for a few months
Añejo – aged longer for deeper, richer flavours
For margaritas, blanco tequila is usually the best choice because it keeps the drink fresh and vibrant.
What Is Mezcal?
Mezcal is also an agave spirit, but it’s produced differently.
The biggest difference is how the agave is cooked.
Instead of steaming the agave in ovens like tequila producers do, mezcal makers cook the agave hearts in underground fire pits, which gives the spirit its famous smoky flavour.
Mezcal can also be made from many different agave species, not just blue agave.
This results in a spirit that is often:
• smokier
• earthier
• more complex
Some cocktail lovers enjoy using mezcal in margaritas to add depth and a subtle smoky twist.
Quick Summary: Tequila vs Mezcal vs Agave
Agave
The plant used to make both spirits.
Tequila
A specific type of agave spirit made only from blue agave in certain regions of Mexico.
Mezcal
A broader category of agave spirits often known for its smoky flavour.
Which Is Best for Margaritas?
Traditionally, margaritas are made with tequila, especially blanco tequila, because its bright citrus-friendly flavour pairs perfectly with lime and citrus mixers.
However, adventurous margarita lovers sometimes swap tequila for mezcal to create a smoky margarita variation.
Both can work — it simply depends on the flavour you prefer.
