Coconut Rum Shots for the Last Few Weeks of Summer

Forty-two proof. That’s the number that explains why coconut rum shots work in August when almost nothing else does.

A standard spirit is 80. Coconut rum is a little over half that, which means a shot of it and some pineapple juice is a mouthful of cold fruit with a little warmth behind it rather than a jolt to the back of the throat. On a ninety-degree afternoon that difference is the whole ballgame. It also means people put away four of them without registering that they’ve had a drink, so I’d pace it.

The other thing about that bottle: it does not keep. Coconut rum has actual ingredients in it, not just alcohol and water, and a bottle opened last June is already past its best. August is when you finish it, not when you put it away for the winter.

The ones I make every year

The Alien Secretion has an awful name and is the best coconut rum shot there is — melon liqueur takes the sweetness somewhere green and faintly herbal, and pineapple juice ties the two ends together. If you make one thing off this page, make that. Its richer cousin is Amaretto Paradise, which adds amaretto for a marzipan weight that holds up when everything else in the glass is cold and bright.

For something that looks like the hour it’s served in, A Day at the Beach layers coconut rum and orange juice over grenadine with amaretto underneath. Pour the grenadine last, don’t stir, and it keeps the sunset gradient.

Then there’s Mounds Bar Shot — coconut rum and creme de cacao, nothing else — which tastes so exactly like the candy bar that it reliably converts the people at the party who announce they don’t like coconut rum. And Blue Coconut, coconut rum with blue curaçao and lemon-lime soda, exists because it is extremely blue. Every kid at the pool asks what it is.

Four I’d add this year

Pineapple juice carries three of these. It’s in 1,575 of our recipes, and the pineapple juice post explains why: its acid is the only thing in the glass that isn’t sweet.

Surfer on Acid

Jägermeister, coconut rum, and pineapple juice, half an ounce each, shaken cold and strained. The Jäger should ruin it and doesn’t. Licorice and herbs under coconut and pineapple, which is why a shot invented in the nineties still gets ordered by name. See recipe

Pro tip: Shake until the tin frosts. Warm Jäger tastes medicinal, cold Jäger tastes like licorice, and only one of those belongs next to pineapple.

Italian Surfer

Two parts pineapple juice, one part amaretto, one part coconut rum, stirred over ice. The Surfer on Acid with the Jäger swapped for amaretto, which makes it sweeter, rounder, and the one to pour for people who flinched at the first version. See recipe

Pro tip: This one scales to a pitcher without losing anything. Two cups pineapple, one cup each of the other two, over ice.

Caribou Lou

151-proof rum, coconut rum, and pineapple juice, roughly one and a half to one to five. The pineapple hides the 151 completely, which is the point and also the problem. In a shot glass it’s the strongest thing on this page by a wide margin. See recipe

Pro tip: Keep the 151 to a quarter ounce per shot. You will not taste the difference and you will notice it an hour later.

Malibu Baked Apple

Coconut rum with heated cranberry and apple juice in a mug, whipped cream on top if you want it. It doesn’t belong in August, but it’s the answer to the bottle that’s still a third full when the porch nights get cold. See recipe

Pro tip: Heat the juice, not the rum. Boiling drives off the alcohol and dulls the coconut.

For a crowd

Anything you can build in a pitcher and pour is worth twice as much on a hot day, because standing over a shaker in the sun gets old before the second round.

Freeze pineapple or mango juice into cubes and use those instead of ice. As they melt the pitcher gets more of itself rather than more water, which is the difference between the first cup and the last one tasting the same. The gelatin ones are covered properly in the jello shot ratio guide if you want them to hold their shape.

Late-evening ones

When it finally cools off and people have moved to the porch.

Almond Kiss — coconut rum in hot chocolate. Absurd in August, perfect on the first cool night of September, and I’d rather you know about it now than find it in December.

Bailey-Bu — Irish cream and coconut rum. Two ingredients, dessert, done.

Almond Joy — coconut rum, amaretto, creme de cacao, half-and-half. Genuinely a dessert. One is enough.

Bone Fish Shot — coconut rum and an energy drink. For when the night is not winding down.

Mug Shot — coconut rum and root beer. Root beer float energy, no ice cream required.

If you’re missing a bottle

• No coconut rum at all: white rum plus a teaspoon of cream of coconut per ounce gets you most of the way, and it’s stronger, so pour less. Coconut vodka (Burnett’s, Smirnoff) works in the juice drinks and not in the creamy ones.
• No melon liqueur (Alien Secretion, Amaretto Paradise): any brand of melon liqueur, or pineapple juice alone. You lose the green and keep the shot.
• No amaretto (Amaretto Paradise, A Day at the Beach, Italian Surfer, Almond Joy): Frangelico, or a half ounce of orgeat. Hazelnut instead of almond, and nobody at the pool will file a complaint.
• No blue curaçao (Blue Coconut): triple sec and a drop of blue food coloring. That is, honestly, what blue curaçao is.
• No Jägermeister (Surfer on Acid): make the Italian Surfer instead. There’s no substitute that tastes like Jäger, and the amaretto version is a real drink, not a consolation prize.

Keeping them cold without watering them down

The problem with tropical shots in August is that everything arrives lukewarm by the third round. Three fixes, in order of effort:

Freeze the bottle the night before. At 42 proof it will get thick and syrupy without freezing solid, and that texture is lovely — the shot pours slow and coats the glass. This alone solves most of it.

Freeze your juice into cubes. Pineapple, mango, orange. They chill without diluting, and as they melt the drink gets more of itself rather than more water.

Chill the glasses, not the drink. A tray of shot glasses in the freezer for twenty minutes buys you the entire time it takes to pour and hand them out.

One honest warning

Coconut rum is sweet, and sweetness plus sun is a combination that catches people out. The sugar makes it go down like juice, the low proof makes it feel harmless, and four of them across an afternoon adds up to a real amount of alcohol while nobody’s paying attention.

Put out a pitcher of water next to the shots. It’s the least host-like thing to think about and the most useful.

If your bottle has been open since last summer, it’s probably faded — coconut rum has real ingredients in it and goes flat and vaguely soapy after a couple of years, unlike plain rum, which keeps almost indefinitely. Smell it before you commit a party to it.

And if there’s a bottle of something else next to it that you also mean to finish before the weather turns, Cocktail Builder is built for exactly that problem.

Frequently asked questions

Is Malibu actually rum?

It’s Caribbean rum blended with coconut flavor and sugar, bottled at 21% ABV, which is 42 proof. Legally it’s a liqueur, not a rum, because a rum has to be at least 40% ABV. Most bottles labeled coconut rum are the same 21%; Bacardi Coconut is the exception at 35%.

What is the most popular coconut rum shot?

The Surfer on Acid and the Alien Secretion, both built on coconut rum and pineapple juice. The Surfer adds Jägermeister; the Alien adds melon liqueur. Order the first at a bar and make the second at home, since it skips the Jägermeister.

Does coconut rum go bad?

Slowly. It won’t spoil, but the coconut flavor fades and the bottle turns flat and slightly soapy after a year or two open. Keep it out of the sun, cap it tight, and finish it within a couple of summers.

What mixes best with coconut rum?

Pineapple juice first, then mango, cranberry, and lemon-lime soda. For dessert shots, Irish cream, creme de cacao, and amaretto. The full rundown is in the Malibu mixers guide.

How strong is a coconut rum shot?

An ounce of 42-proof coconut rum has about half the alcohol of an ounce of vodka. A shot cut with pineapple juice lands around 10 to 20% ABV depending on what else is in it, which is wine strength or a little above, in a two-ounce glass.
