Ask for a “caguama” anywhere else in the Spanish-speaking world and people will picture a sea turtle. Ask for one at a corner store or taqueria in Mexico and you will get a beer, specifically a big one. It is one of the more useful words to know if you are ordering beer in Mexico, because the size difference between a caguama and a regular bottle is bigger than most first-time visitors expect.
What Exactly Is a Caguama?
A caguama is a large-format beer bottle in Mexico, holding 940 milliliters, which is just under a liter and roughly 32 US fluid ounces. That works out to about 2.7 standard 12oz beers in one bottle, big enough to split between two people at a meal or finish alone over a long lunch. The name is a direct borrow from the Spanish word for the loggerhead sea turtle, and the connection is exactly what it sounds like: the bottle’s rounded, heavy-bottomed shape resembles a turtle’s shell.
Where the Name Actually Came From
The term dates back to the 1960s, when Cervecería Cuauhtémoc introduced the large-format bottle as a value option and drinkers started calling it after the turtle shape. According to the Diccionario Enciclopédico de la Gastronomía Mexicana, once the nickname caught on it stopped being brand-specific. Any 925ml-940ml bottle, regardless of which brewery made it, gets called a caguama in everyday Mexican Spanish. The word has even spawned its own verb, caguamear, meaning to sit around drinking one (or several).
Caguama vs. Other Mexican Beer Sizes
Mexican beer comes in a confusing number of named sizes, and caguama is only one rung on the ladder. Here is how the common ones stack up:
| Name | Size | Roughly Equal To |
|---|---|---|
| Cuartito / media | 355ml | 1 standard 12oz beer |
| Caguama | 940ml | 2.7 standard 12oz beers |
| Ballena (“whale”) | 1.2 liters | 3.4 standard 12oz beers |
| Caguamon | 1.4-1.8 liters (varies by region) | 4-5 standard 12oz beers |
Note the pattern: bigger animal name, bigger bottle. A ballena (whale) is bigger than a caguama (turtle), and a caguamon is just a caguama with an exaggerating suffix tacked on for something even larger.
What Actually Comes in Caguama Bottles
Almost every major Mexican lager brand bottles a caguama-sized version, since it is a standard SKU rather than a novelty format. Corona Familiar, Pacifico, Sol, Victoria, Indio, and Bohemia all commonly ship in the 940ml size, usually at the same 4-4.5% ABV as their standard bottles. It is priced to be cheaper per ounce than buying the equivalent in smaller bottles, which is a big part of why it became the default choice for a group meal instead of a novelty gimmick.
Why the Big Bottle Became the Default, Not a Novelty
A lot of large-format drink containers exist as one-off gimmicks (a yard of ale, a boot glass), but the caguama is genuinely the everyday size in a huge amount of Mexican beer retail, not a party trick.
The economics explain why: at most corner stores and abarrotes, the price per milliliter drops noticeably once you move from a 355ml bottle to a 940ml one, since it is one bottle, one cap, and one label instead of nearly three of each. For a brewery, it is also cheaper to fill and cap one large bottle than three small ones. That cost saving gets passed on, which is why a caguama at a taqueria or a corner store is almost always the better deal per ounce, not just the bigger option.
It also fits how beer actually gets consumed with food in Mexico. A caguama is built to be shared across a meal rather than finished solo in one sitting, since 940ml poured into a few small glasses (a common serving method, rather than drinking straight from the bottle) covers two or three people through a plate of tacos or a torta without anyone needing a second bottle. That is different from the US 40oz malt liquor bottle it sometimes gets compared to, which culturally reads as a single-serving format for one person rather than something split at a table.
How Caguamas Get Served
Straight from the bottle is common enough, but pouring into small glasses (vasitos) is the more traditional way to serve one, especially at a sit-down meal. It also means everyone at the table can top up as they like rather than passing one bottle around. Caguamas are also the usual base for a michelada or a chelada made for a group: a big bottle of lager mixed with lime, salt, and either just a chili-salt rim (chelada) or the fuller tomato-and-chili-sauce version (michelada) scales better from one large bottle than from several small ones, since you are mixing one batch of seasoning instead of several. If you want the actual recipe ratios, our michelada recipe walks through it step by step.
For a look at which brands are actually worth reaching for regardless of bottle size, our Mexican beer brands roundup ranks the major lager brands you’ll find in caguama format.
The Brewery Behind the Name
Cervecería Cuauhtémoc, the brewery credited with popularizing the format in the 1960s, was founded in Monterrey in 1890 and is one of the oldest breweries in Mexico. It later merged into what became Cervecería Cuauhtémoc Moctezuma, now part of Heineken’s Mexican operations, and its lineup (Carta Blanca, Indio, Tecate, Bohemia) still shows up in caguama-sized bottles on shelves today. The brewery’s original marketing push behind the big bottle in the 1960s was straightforwardly about value: more beer, one bottle, lower cost per ounce, aimed at working-class drinkers rather than at tourists or a novelty market. That the nickname outlived the specific marketing campaign, and now applies to any large bottle from any brand, is part of why it reads as a genuine piece of everyday Mexican Spanish rather than a branded gimmick.
Caguamera Culture and the Verb It Created
The word’s staying power in Mexican Spanish is visible in how many related terms spun off from it. A caguamera is a cooler or insulated sleeve made specifically to fit the oversized bottle, sold in the same aisles as the beer itself. Caguamear, the verb mentioned earlier, describes the act of sitting around drinking one, usually slowly, usually social, closer in feeling to “having a few beers on the porch” than to a single quick drink. None of this vocabulary exists around a standard 355ml bottle, which is a good sign of how specifically tied to the format, rather than to beer in general, the caguama identity really is. It has also crossed the border along with the drinking habit: in parts of the southwestern US with large Mexican-American communities, “caguama” gets used the same way at stores that stock the large-format imports, even though it never became standard English.
What to Actually Buy If You Want to Try One
If you’re picking up a caguama-sized bottle, here’s the brand roundup to start from, plus the two things most people end up wanting alongside it: something to keep the bottle cold once it’s open, and the seasoning for a michelada if you’re mixing it rather than drinking it straight.

How many regular beers is one caguama?
A 940ml caguama is roughly equal to 2.7 standard 12oz (355ml) beers, so a bit under three regular bottles.
