On The Rocks launches a limited Passion Fruit Margarita Ready to Drink and sparkling watermelon RTD — both made with Hornitos Blanco. Find them now.
The best margarita you’ll have this summer might come from a bottle. Not a bar cart someone dragged out for a birthday. Not a pitcher of neon mix that smells like sunscreen. A bottle, cracked open over ice, that actually tastes like the drink a good bartender would hand you.
On The Rocks Bartender Created Cocktails just launched two new expressions built on Hornitos Blanco Tequila: a limited-edition Passion Fruit Margarita in a 375mL bottle and a permanent Sparkling Watermelon Margarita in 4-packs. Both are available now nationwide. Both are aimed at the same moment — the one where the occasion is right and the bar is not.
The passion fruit margarita ready to drink category has been quietly building for two years. On The Rocks is betting that moment is now.
Why Passion Fruit, and Why Now
Passion fruit is having a real run behind the bar. Bartenders in LA, Miami, and New York have been reaching for it as a way to add tartness with complexity — it delivers brightness without the one-note sweetness of strawberry, and acidity without the aggression of straight citrus.
The On The Rocks Passion Fruit Margarita opens with ripe tropical fruit — the kind that reads slightly fermented and floral before the Hornitos Blanco cuts through with its clean agave character. The finish is tart rather than sweet, which is exactly what keeps a margarita from becoming a dessert.
Global Ambassador and mixologist Joaquín Simó put it plainly: “Passion fruit cocktails are popular at the bar right now, as people look to expand their palates and riff on their favorite classic cocktails. When crafting the limited-edition On The Rocks Passion Fruit Margarita, it was all about capturing the essence of this delicious, tropical fruit — striking that ideal balance of tart and sweet that makes margaritas so easy to love.”
That balance is the work. Getting tart and sweet right in a bottled format — without a bartender adjusting on the fly, without fresh juice from a squeeze — is harder than it sounds.
Most RTD margaritas choose a side and commit: they’re either candy-sweet or bracingly sour, like a dare. This one doesn’t.
The Watermelon Expression Is Built to Stay
While the Passion Fruit is limited, the Sparkling Watermelon Margarita is a permanent addition to the lineup — which signals On The Rocks’ confidence in where this flavor is headed.
Made with Hornitos Blanco, house-made triple sec, and cane sugar, the sparkling format changes the drinking experience in a specific way.
Carbonation lifts the watermelon note, making it read lighter and more refreshing than a still version would — closer to a agua fresca on a hot afternoon than to the thick, over-sweetened watermelon cocktails that dominated the category a few years ago.
It’s the right call for a can. The format demands something that drinks easily, and watermelon with a touch of fizz earns that.
The RTD Category Has Grown Up
On The Rocks was founded in 2015 by restaurateurs and bartenders who left fine dining with a specific thesis: that bar-quality cocktails could exist outside the bar. The brand built its early credibility in airlines and hotels — places where a good drink was rare and a bad one was guaranteed.
There’s something quietly satisfying about the fact that Simó — a bartender with serious craft credentials — is the architect of drinks designed for situations where no bartender is present. The bar comes to you, which is either a triumph of convenience or an argument that the bar was always overrated as a location. Probably both.
Hornitos Blanco is doing real work in both expressions. It’s an agave-forward tequila with enough presence to anchor the fruit without disappearing into it — which matters, because tequila that vanishes in a cocktail is just expensive sugar water.
Simó’s framing is worth repeating: “Margarita season is a state of mind and these new cocktails are made to take you there. The new On The Rocks margaritas are ready to be cracked open on a patio, poured over ice at a BBQ, or enjoyed on any occasion that calls for a little more sunshine.”
Mini FAQ
What tequila is used in On The Rocks margaritas?
Both the Passion Fruit and Sparkling Watermelon Margaritas are made with Hornitos Blanco Tequila, an agave-forward blanco produced by Suntory Global Spirits. Hornitos Blanco is clean and lightly sweet, making it well-suited for fruit-forward cocktail builds.
Is the On The Rocks Passion Fruit Margarita a permanent product?
No. The Passion Fruit Margarita is a limited-edition release available in 375mL bottles at an SRP of $12.99. The Sparkling Watermelon Margarita, available in 4-packs at the same price, is a permanent addition to the lineup.
Where can I buy On The Rocks cocktails?
Both expressions are available now at retailers nationwide. The full On The Rocks portfolio — including Espresso Martini, Old Fashioned, and Sparkling Lime Margarita — is available at otrcocktails.com.
One More Reason to Open the Patio
The Passion Fruit won’t be around forever. That’s not a sales pitch — it’s just the math of a limited release. If you’ve been waiting for something that actually tastes like the margarita you ordered on vacation, this is a reasonable place to start. The Sparkling Watermelon will be there when summer becomes a habit.
