Ghoul’s Grapefruit Cooler Mocktail Recipe

You get a tangy citrus taste and a refreshing twist here. It’s easy enough to whip up at home, and you probably have most of the stuff already.

Equipment

• Cocktail shaker: I always grab my shaker to mix everything up.
• Strainer: Keeps out any pulp or seeds.
• Martini glass: Makes the drink feel a bit more special.
• Measuring jigger: Super helpful for getting the amounts right.
• Citrus juicer or reamer: I use this to squeeze every drop from the fruit.
• Spoon: Just in case you need to stir.
• Small knife and cutting board: For cutting fruit, of course.

Ingredients

• 1/2 cup grapefruit juice (fresh is best, trust me)
• 1/4 cup apple juice (clear, unsweetened is my go-to)
• 2 tablespoons lemon juice (fresh for extra zing)
• 1 to 2 tablespoons simple syrup (less if you like it tart, more if you want it sweeter)
• 1/2 cup crushed ice (for that cold, slushy vibe)
• Grapefruit or lemon wheel (optional garnish)

I try to use juices that are as fresh and chilled as possible. It really makes the drink pop.

Instructions

• Fill your cocktail shaker about halfway with crushed ice.
• Add in the grapefruit juice, apple juice, lemon juice, and simple syrup.
• Put the lid on and shake it hard—about 20 seconds does the trick.
• Strain into a martini glass.
• If you want, pop a slice of grapefruit or lemon on the rim.
• Serve right away while it’s icy cold.

I always shake it up well to get everything chilled and mixed. Straining keeps out any unwanted pulp or seeds.

Notes

If you’re not big on sweet drinks, just dial back the simple syrup or skip it. Sometimes I toss in a bit more lemon juice for extra tartness.

Want bubbles? Add a splash of sparkling water on top after you pour. For a spookier look at parties, I’ll float a slice of blood orange instead of regular citrus.

If I’m making a batch for friends, I just double everything. Fresh juice really does make all the difference.

Tasting Notes

First sip, and the Ghoul’s Grapefruit Cooler is just so refreshing. The grapefruit juice brings a bright, citrusy punch right up front.

It’s not too sweet, not too tart—just a nice balance of both. If you add sparkling water, the bubbles give it a light, lively feel.

Here’s what stands out to me:

• Color: Pinkish, with a bit of orange
• Aroma: Fresh grapefruit, maybe a hint of mint
• Texture: Smooth, with some fizz

After a couple sips, I notice a cool, minty note from the mint garnish. It’s subtle, not overpowering.

If you’re into drinks that aren’t a sugar bomb, this one’s probably up your alley. Grapefruit is the star, but everything just works together.

Honestly, I love how crisp it is—especially if it’s warm out.

Substitute

Sometimes I just don’t have everything on hand. When that happens, here’s how I swap things in my Ghoul’s Grapefruit Cooler Mocktail.

Equipment substitutes:

• No cocktail shaker? Honestly, I just grab a mason jar with a tight lid and call it a day.
• I’ve also used the back of a wooden spoon instead of a muddler, and it works surprisingly well.

Ingredient swaps:

• Out of grapefruit juice? I’ll use orange or even tangerine juice if that’s all I’ve got.
• For a tangy twist, I’ll switch lemon juice for lime juice—it’s not quite the same, but it’s still good.
• If there’s no club soda around, plain sparkling water gets the job done.

Instructions for swapping:

• When I switch up the juice, I just use the same amount as the recipe says.
• If my substitute is on the sweeter side, I go easy on the sweetener and taste as I go.
• Trying a new flavor? I usually make a tiny test batch first, just in case.

Sometimes, I’m after a little more fizz. I’ll throw in a splash of flavored seltzer instead of plain sparkling water. Honestly, the drink turns out a bit different every single time—and I kind of like that.
