About Bikini Martini
A bikini martini is a beach-and-sun-loving martini for all the best reasons.
It has a crisp, sweet flavor with hints of pineapple and coconut, and a pretty layered presentation with bright, fun colors.
Plus, it’s easy to make and fun to garnish, making this tropical martini an ideal choice to whip up for warm-weather gatherings.
What’s in a bikini martini?
To craft this fun-living drink, you’ll need to have the following on hand:
- Pineapple Juice – Any brand you’d like to use. Note that this should be pineapple juice and not pineapple juice cocktail.
- Coconut Rum – A classic for summer drinks, it has a soft flavor that’s reminiscent of coconut water.
- Vodka – Any non-flavored type or brand will do.
- Grenadine – Another mixed drink favorite, this helps smooth out the flavor while also adding the eye-catching red hue at the bottom of the drink.
- Pineapple and/or Maraschino Cherries – Only used as a garnish but they really up the presentation of the drink.
How does this drink have layers?
Also called stacked drinks, layered drinks like this bikini martini are created by combining drinks with different sugar content and manipulating their weight. For example, grenadine has a high sugar content, making it thicker and heavier than the combination of pineapple juice, vodka, and coconut rum. When poured slowly, the grenadine will sink to the bottom of the glass while the lighter, less sugary liquids will float above.
Can you make this martini without alcohol?
Yes, you can, but doing so may change the flavor, consistency, or look of the drink, depending on which method(s) you use.
You can skip the alcohol and either omit it entirely or replace this with an equal amount of pineapple juice.
For the coconut rum, you can substitute this for equal parts coconut water or coconut milk. Coconut milk might be closer in taste, but the martini may look more cloudy. There is also cream of coconut, but this is considerably thicker, so this would have the biggest visual impact and could potentially make the drink too sweet. So, in short: coconut water is likely your safest bet, while coconut milk could work in a pinch.
How to measure this martini
This martini is written like a standard drink recipe, meaning that instead of an exact measurement (ex: 1 cup) the recipe will read “1 part.”
This can sometimes be a little confusing, but I’ve found the best way to think of it as this: Recipes that measure in parts usually mean it’s written so that you can adjust the size of the drink to whatever you want and the measurements they give you (1 part, 1/2 part, etc) are so you can keep the ratio of the ingredients correct.
For example, let’s say you wanted to make one drink – this typically means you’re using 1 standard shot glass for measuring. So then when the recipe says “1 part” you would interpret that amount as “1 standard shot glass” full. If the recipe says “1/2 part” you’d fill the shot glass halfway so that it’s “1/2 standard shot glass.” OR, let’s say you wanted to make enough drinks for a few friends. When making the drink you could interpret “1 part” as “1 cup” (or “1/2 part” to “1/2 cup.”)
This way the drink will taste the same no matter what size you make it.
What are the exact measurements for one drink?
In a hurry and want simple measurements for just one drink? No problem! Just use this as a guide:
- 2 oz pineapple juice
- 1 1/2 oz coconut rum
- 1 1/2 oz vodka
- 1/2 oz grenadine
You can also select “Metric” measurements in the recipe card below to see these numbers.
Notes & tips for this bikini martini
- With any mixed drink, it’s best to use chilled ingredients whenever possible. This will ensure the ice in the cocktail shaker does not melt too much and water down the drink before it’s even served.
