Once upon a time, two friends bought a hacienda in Mexico to drink their own tequila. The hacienda was real. The tequila was excellent. And the two friends, George Clooney and Rande Gerber, accidentally built a billion-dollar brand they hadn't quite meant to start.

The Casamigos story is the kind of origin tale that sounds invented even when it isn't. It involves blue agave, a few hundred private parties, a phone call from Diageo, and a sale price (a billion dollars, with a possible three hundred million more in performance kickers) that quietly reshaped how the spirits world thought about celebrity ownership.

The thing is, and this is the part the cynics tend to skip, the tequila was already good before any of that happened.

The story they tell, and the parts they don't

The official line is well-rehearsed. Clooney and Gerber, longtime friends, were spending more and more time at their adjoining houses in Cabo San Lucas. They drank a lot of tequila. They drank a lot of bad tequila. So they asked a master distiller to make them something they actually wanted to pour after dinner. A small batch, for personal use, no commercial intent.

They named it Casamigos: house of friends. They had it produced in Jalisco, in the small town of Atotonilco el Alto, from estate-grown blue Weber agave aged seven to nine years. They drank it with their friends. The friends asked where it was from. The friends asked for cases. The pretence of a private label lasted about as long as you'd expect when one of the friends is one of the most famous men in the world.

By 2013, Casamigos was a real brand. By 2017, it was Diageo's. By the late 2020s, Clooney has reportedly made more money from tequila than from any film he's ever been in. There's a punchline in there somewhere about Hollywood economics, but the joke writes itself.

And now, the beer

In March 2026, the same Casamigos trio (Clooney, Gerber, and Mike Meldman, the third partner who tends to sit a little quieter in the founding photograph) launched Crazy Mountain, a premium non-alcoholic beer brand announced as a 65-calorie bottle and marketed, with a slightly bewildering tagline, as a “beer-only freer”. It is the same trio who sold Casamigos to Diageo in 2017 for up to a billion dollars, betting again that the affluent drinker will follow good company into a new category. Casamigos took its time getting there. The beer can presumably do the same.

What's actually in the bottle

Casamigos is made the orthodox way: kiln-cooked agave, no shortcuts, no diffuser. The piñas are cooked for 72 hours in traditional brick ovens, twice as long as most large producers bother with. The result is an unusually approachable spirit. Softer than its peers, faintly sweet on the finish, with the kind of vanilla-and-agave roundness that makes it dangerously easy to drink straight.

There are three core expressions. The Blanco is unaged, all green agave and citrus pith: clean, bright, made for cocktails. The Reposado, aged seven months in American oak, lands somewhere between a margarita workhorse and a sipping pour. Caramelised pineapple, vanilla, a faintly buttery finish. The Añejo, fourteen months in oak, is the one Clooney apparently drinks himself: darker, woodier, with notes of dark chocolate, dried fig, and a long warm finish that doesn't bite back.

Casamigos also makes a Mezcal, which is worth knowing about. Smokier than its cousin, made from espadín agave, less aggressive than most of the artisanal mezcal coming out of Oaxaca. It's an easier introduction to the category than throwing yourself at a Del Maguey Tobalá on a Tuesday night.

The criticism, addressed

Casamigos has, predictably, attracted the suspicion of agave purists. It's smooth. Too smooth, some argue, suggesting added sweetener or glycerine. The brand denies any additives, and Diageo's quality protocols since acquisition would make the alternative awkward to defend. What's likely true is more interesting. The cooking time, the slow fermentation, and the choice of softer oak (American, not French) all push the spirit toward roundness without doing anything technically illicit. The smoothness is engineered, not faked.

The other complaint, that you're paying for the celebrity rather than the liquid, is harder to dismiss outright. Casamigos sits at a premium price point that some bars will tell you is unjustified by tasting alone. There are plenty of better-value tequilas at the same price point, particularly from smaller producers like Fortaleza or Tequila Ocho.

How to drink it (and how not to)

The Blanco belongs in a Paloma or a margarita: anywhere lime and citrus give it work to do. The Reposado is your Old Fashioned tequila, the one for slow stirring and an orange peel. The Añejo wants nothing more than a good rocks glass, one large cube of ice, and the patience to let it open up over fifteen minutes.

Don't shoot it. Don't sour-mix it. Don't, for that matter, pretend you don't want a second pour.

The verdict, such as it is

Casamigos is not the most interesting tequila in the world. It's not the most punishing, the most expensive, or the most artisanal. What it is, and this is no small thing, is reliably good, available everywhere, and easy to like. It's the bottle you pour for friends who don't normally drink tequila and watch their faces change.

George Clooney's accountants are doing fine. The drinkers are too. And on that count, the friendship that built the brand has held up rather well.
