How to Make a Melon Matcha Sparkling

What you need

• a knife
• a cutting board
• a bowl or container
• a silicone spatula
• a kitchen scale
• a fine strainer or sifter
• a bamboo whisk or a milk frother
• a tall glass

Method

1. Make the melon syrup ahead: halve the melon, remove the seeds, and slice the flesh as thinly as possible, then cut into long quarters.

   Slicing thin draws out more juice, which gives a stronger melon aroma.

   Expert tipSqueeze in the extracted juice as you measure so it counts toward the volume.

2. Weigh the sliced melon with its juice, then add white or xylose sugar at about 80-90% of that volume rather than a full 1:1.

   Melon is already quite sweet, so a 1:1 syrup makes the final drink hard to balance.

   Expert tipTaste once the sugar dissolves; if it is too sweet, add lemon juice equal to about 5% of the fruit.

3. Stir to dissolve the sugar with a silicone spatula, redissolving any that settles, then refrigerate to age for 2 days before using.

   One day tastes fresher; two days gives the fullest flavor.

4. Sift or strain the 100% matcha, or loosen the portion you need with a spoon, to break up any clumps.

   100% matcha clumps easily; loosening it first helps it foam better.

5. Add about 50g of 70-80C water to the matcha and whisk smooth with a bamboo whisk, or aerate it with a milk frother.

   Hand-whisking gives a softer, fuller aroma and texture, while a frother is the practical option.

6. Pour only the liquid from the melon syrup into the bottom of a tall glass, then add unsweetened sparkling water at about twice the amount of syrup.

   If it tastes too sweet, add another 10-20g of sparkling water.

   Expert tipThe fineness of the bubbles varies by brand, so choose a sparkling water you like.

7. Fill the glass with ice, then gently float the whisked matcha on top to create a two-tone layer.

8. Garnish with a large-leaf edible herb, and optionally rub lemon zest over the top for a fresher, citrus note. Tell the guest to stir well before drinking.

Why this works

Using only the liquid from an aged melon syrup gives a clean, balanced sweetness without the texture of pulp, while sifting the 100% matcha and whisking it with warm water keeps it smooth and aromatic rather than clumpy. Layering syrup, sparkling water, and a floated matcha builds a two-tone drink where the carbonation lightens the body and the matcha stays nutty instead of harsh.

Where beginners go wrong

1. 1

   Matcha turns lumpy

   Sift or strain the 100% matcha before whisking; loosening it first also helps it foam.

2. 2

   Drink tastes too sweet

   Add another 10-20g of unsweetened sparkling water, and keep the syrup sugar at 80-90% rather than 1:1.

3. 3

   Weak melon aroma

   Slice the melon as thinly as possible so it releases more juice, and age the syrup about 2 days before using.

What you should taste

Light and refreshing with a soft, gently sweet melon aroma carried by fine carbonation; the matcha reads more nutty and mellow than bitter, with an optional bright lift of citrus from the lemon zest.
