Ingredients & Substitutions
- Grapefruit: Use freshly squeezed grapefruit juice. You can use store bought grapefruit juice as well, but it won’t have the same, fresh flavor.
- Vodka: For this drink, use a medium quality vodka. You can replace this with gin if you prefer gin-based martinis.
- Lime Juice: Use freshly squeezed lime juice rather than artificial lime juice. For a brighter, citrusy flavor, you can use lemon juice instead.
- Triple Sec: Triple sec adds a subtle orange taste. You can replace this with Cointreau.
- A citrus reamer for juicing the grapefruit.
- A cocktail shaker for making the martini.
- Martini or coupe glasses to serve the drink in.
Step 1: Add the grapefruit juice, vodka, lime juice and triple sec to a cocktail shaker filled with ice.
Step 2: Shake well for 5 to 10 seconds until the outside of the shaker is frosted. Strain and serve into a chilled glass.
- Chill the glasses in the freezer. Martinis are best served extra cold. Chill your martini or coupe glasses in the freezer before serving this cocktail.
- Garnish your martini. If you are serving this martini to guests, add a simple garnish. Try a round slice of grapefruit on the edge of the glass, or an orange twist.
- Adjust the sweetness. You can make this martini as sweet or as sour as you like. For a more sour drink, add extra freshly squeezed grapefruit juice. For a sweeter drink, add an extra splash of Triple Sec, or add in ½ oz of homemade simple syrup.
- Mocktail: For a mocktail variation, replace the vodka and Triple Sec with a splash of sparkling water and orange juice. Or try this grapefruit paloma mocktail.
- Herby: For a subtle herb flavor, add in ½ oz of a flavored herb simple syrup, such as this thyme simple syrup, this basil simple syrup or this rosemary simple syrup.
- Fizzy: For a bubbly cocktail, top off the martini with some sparkling water or prosecco.
Yes. Mix all the ingredients together and store them in the fridge. Don’t add in any ice until ready to serve, otherwise it will be watered-down. Shake in a cocktail shaker with ice right before serving.
You can serve this drink without shaking it in a cocktail shaker, but it tastes better when shaken. Citrus cocktails are best shaken because the ice breaks down the tart grapefruit flavor, making it a light and refreshing cocktail.
If you don’t have a cocktail shaker, fill a large mason jar with ice. Add the ingredients and put on the mason jar lid. Shake well and strain out the ice before serving.
