Ingredients and substitutes
Please scroll down to the recipe card for the ingredient quantities!
- Pink grapefruits - You can juice your own grapefruits or use non-sweetened grapefruit juice. Also, save a grapefruit and thinly slice it for garnish.
- Sugar - You can use any granulated sugar, although, plain granulated white sugar gives the purest grapefruit flavors.
- Tonic water - Tonic water is a little bitter, so it'll go perfectly with the grapefruit and matcha. However, it does have added sugar. So if you prefer, substitute the tonic water for your preferred carbonated beverage such as, sparkling water or club soda.
- Matcha - We highly recommend using at least a universal grade matcha for better flavor and color. Culinary grade matcha is better for baking and would yield a dull green color matcha tonic. If your budget allows, try it with some ceremonial grade matcha! You'll see the difference between both color and flavor.
- Water - For mixing the matcha powder. It can be either room temperature or cool.
How to make grapefruit matcha tonic
For the homemade grapefruit syrup:
2. Add the grapefruit juice and sugar into a small saucepan and place it over medium high heat. Stir occasionally until the sugar is completely dissolved.
3. Transfer the grapefruit syrup to a sanitized jar and let it cool completely before covering and refrigerating. Set aside until needed.
For each serving of grapefruit matcha tonic:
1. Add 3 tablespoons of the homemade grapefruit syrup into a glass. If you want to add a slice of grapefruit for garnish, place it against the glass now.
2. Then, add your desired amount of ice to the glass, followed by the tonic water. Remember, the ice will melt when you add the remaining liquid, so add a little more than you'd like.
🌟 Pro tip: If you're using a straw, stick a straw into the drink now, before adding the matcha. This will ensure the drink's layer doesn't get disturbed and you'll have time to take pictures to your hearts content!
2. In a small bowl or matcha bowl, add the matcha powder. Add about half of the water and mix with a matcha whisk until no more lumps of matcha remain. Then, add the remaining water and whisk briskly until slightly foamy.
3. Gently, pour the matcha into the glass, over the tonic water. Repeat with the other glass. Stir and enjoy!
- Use good quality matcha. We recommend using at least a universal grade matcha for better flavor and color.
- Adjust the sweetness per your preference. Feel free to use more or less grapefruit syrup for adjust the sweetness of this tonic.

Grapefruit syrup storage
Although the grapefruit matcha tonic is best enjoyed after making, you can make the grapefruit syrup ahead of time!
After making the grapefruit syrup, transfer it to a sanitized container, like a mason jar. Let the syrup cool completely before covering and refrigerating. The syrup will be good for about 7 to 14 days.
Tonic water is a carbonated beverage with quinine added to give it its iconic bitter flavor. You'll most likely find added sugar in tonic water to help balance the bitter flavor.
For this grapefruit matcha tonic, you can substitute the tonic water for your preferred choice of sparkling water, club soda, or any other unsweetened or lightly sweetened carbonated beverage.
We highly recommend using at least a universal grade matcha for making matcha beverages because the matcha flavor and color will both be better. If your budget allows, try out some ceremonial grade matcha!
