St. John Sour Cocktail Recipe – A Tropical New York Sour Riff

Sometimes a vacation cocktail happens because you’re chasing inspiration. Sometimes it happens because you look around the rental house, spot a bottle of cabernet, a bottle of coconut rum, and decide that Future You can deal with the consequences.

Fortunately, Future Me was pretty happy with this one.

The St. John Sour borrows the layered wine float from a New York Sour but takes the flavor profile somewhere much more tropical. Pineapple and orange juice bring the island vibes, lime keeps everything from becoming a sugar bomb, and the cabernet float adds just enough dryness and complexity to make you wonder why more tropical cocktails don’t steal this trick.

Recommendation: get a bottle of Cruzan Coconut Rum. It’s not expensive, and Cruzan Coconut tends to be less candy-like and more rum-forward than, say, Malibu.

Why I Tried This

I was spending time on St. John in the U.S. Virgin Islands and wanted something that felt appropriately tropical without defaulting to another frozen drink. The idea started as a New York Sour-inspired experiment, except with coconut rum standing in for whiskey and fruit juices doing the heavy lifting.

Because look — if you’re surrounded by turquoise water and palm trees, making a serious whiskey sour feels a little like wearing a tuxedo to the beach, right?

How It Turned Out

Sweetness

The pineapple juice provides most of the sweetness, while reducing the orange juice to one ounce keeps things from becoming overly fruity. The wine float also helps pull everything back toward balance.

Balance

This is where the drink surprised me. The lime gives the cocktail enough acidity to stay refreshing, and the cabernet float adds a subtle dryness that prevents the tropical flavors from becoming one-dimensional.

Mouth Feel

Light, juicy, and refreshing. The wine float creates a little extra texture and complexity as the layers gradually mix together.

Notes & Fine Tuning

• If you prefer a tarter cocktail, increase the lime juice to a full ounce.
• A fruit-forward cabernet works best. Avoid anything excessively oaky or tannic.
• Dark rum can create an interesting variation, though you’ll lose some of the coconut character.
• For a stronger wine presence, increase the float to ¾ oz.

Flavor Expectation

Expect pineapple up front, followed by coconut and citrus. The cabernet doesn’t dominate the drink but adds a subtle berry note and a dry finish that keeps the tropical flavors in check. Think beach cocktail meets wine bar, which sounds ridiculous until you taste it.

Overall Balance

A refreshing tropical sour that walks a surprisingly successful line between fruity beach drink and classic sour template. The cabernet float turns what could have been a simple rum punch into something a little more interesting.

A tropical riff on the classic New York Sour, the St. John Sour swaps whiskey for coconut rum and layers pineapple, orange, and lime beneath a float of cabernet sauvignon. The result is bright, fruity, slightly tart, and surprisingly balanced.
