Ingredients

2 servings

2 tsp (4 g) culinary or ceremonial-grade matcha powder, sifted through a fine-mesh sieve
¼ cup (60 ml) hot water, heated to about 175°F (80°C)
1½ cups (360 ml) unsweetened coconut water, well chilled
3 tbsp (45 ml) fresh lime juice, freshly squeezed and strained of seeds (from about 2 limes)
2 tbsp (42 g) light agave syrup
2 cups (280 g) ice cubes, for shaking
2 cups (280 g) ice cubes, fresh, for serving
2 thin wheels (20 g) lime, cut into thin rounds, for garnish
2 sprigs (4 g) fresh mint sprigs, gently slapped between palms to release aroma (optional)

Equipment (8)

Cocktail shaker (16–24 oz / 500–700 ml) with tight-fitting lid
Small fine-mesh sieve
Small bowl or matcha bowl (chawan), about 12 oz / 350 ml
Bamboo whisk (chasen) or small hand frother
Citrus juicer
Measuring spoons and jigger
2 tall glasses (12 oz / 350 ml)
Cocktail strainer or the shaker's built-in strainer

Steps

Before you start

Chill the coconut water for at least 2 hours so the drink stays cold without over-diluting.
Juice the limes right before using; bottled juice tastes flat next to matcha.
Sift the matcha: unsifted powder leaves green clumps that will not dissolve in a shaker.
Use water that is about 175°F (80°C), not boiling, to avoid bitter matcha.

1
Prep glasses and garnish
- Place 2 tall 12-oz (350 ml) glasses in the freezer or fill with cold water to chill.
- Cut 2 thin lime wheels from one lime, then juice the limes to get 3 tbsp (45 ml) juice, straining out seeds.

Ready when: You have 3 tbsp (45 ml) of seed-free juice and 2 intact lime wheels.
Tip: Cut the wheels before juicing; a squeezed lime is hard to slice neatly.
2
Sift the matcha
- Set a fine-mesh sieve over a small bowl.
- Add 2 tsp (4 g) matcha and press it through with the back of a spoon.

Ready when: The powder is fine and fluffy with no visible lumps.
Tip: Sifting is what prevents gritty green specks in the finished drink.
3
Whisk matcha pasteOven 175°F / 80°C
- Pour 1/4 cup (60 ml) hot water at about 175°F (80°C) over the sifted matcha.
- Whisk briskly in a zigzag 'W' motion for 20–30 seconds, or use a hand frother.
+ Show details− Hide details
Ready when: The matcha is smooth, deep green, and topped with fine foam, with no dry clumps on the bowl's sides.
Tip: Boiling water makes matcha taste bitter. If you have no thermometer, let just-boiled water sit 2–3 minutes.
4
Cool the matcha
- Let the whisked matcha sit for 2 minutes so it is no longer steaming.
- This keeps the ice from melting too fast in the shaker.

Ready when: The bowl feels warm, not hot, to the touch.
5
Load the shaker
- Add 2 cups (280 g) ice to the shaker.
- Pour in the matcha, 1 1/2 cups (360 ml) chilled coconut water, lime juice, and 2 tbsp (42 g) agave syrup.
+ Show details− Hide details
Ready when: Ice fills the shaker about two-thirds full and the liquids cover it.
Tip: Do not overfill the shaker; the drink needs room to move to get frothy.
6
Shake hard
- Seal the lid firmly and shake vigorously for 15 seconds.

Ready when: The outside of the shaker is frosty and cold, and you can hear the ice rattling freely.
Tip: Hold the lid and base with both hands; the contents are cold and slippery.
7
Taste and adjust
- Open the shaker and taste a small spoonful.
- Add 1 tsp more agave if too tart, or 1 tsp more lime juice if too sweet, then reseal and shake 5 seconds.

Ready when: The flavor is balanced: grassy matcha, bright lime, gentle sweetness.
8
Strain and serve
- Fill the chilled glasses with 2 cups (280 g) fresh ice.
- Strain the drink evenly into the glasses, leaving a foamy top.
- Garnish each with a lime wheel and a mint sprig if using.
- Serve immediately.

Ready when: Each glass has a pale green, frothy surface and sits about 1/2 inch (1 cm) below the rim.
Tip: Use fresh ice, not the shaken ice, which is partly melted and will water the drink down.

Good to know

Tips

Choose a bright green matcha; dull or yellowish powder tastes bitter and flat.
Taste coconut water first: brands vary in saltiness and sweetness, so adjust agave accordingly.
For a creamier version, replace 1/4 cup (60 ml) coconut water with canned coconut milk.
Serve right away; matcha settles within minutes and the froth fades.

Make ahead

"Whisk the matcha with hot water, cool it, and refrigerate in a sealed jar for up to 8 hours. Juice the limes up to 4 hours ahead. Shake with ice just before serving."

Storage & reheating

"Best served immediately. Leftover shaken drink (without ice) keeps in a sealed jar in the fridge up to 12 hours; matcha settles and the color dulls, so shake or stir well before serving over fresh ice. Not suitable for freezing as a finished drink, though it can be frozen into ice cubes for up to 1 month and used to chill future batches. No reheating needed."

Substitutions

light agave syrup → Honey or simple syrup. Use the same amount; honey is not vegan. If using honey, stir it into the warm matcha so it dissolves.
fresh lime juice → Fresh lemon juice. Gives a softer, slightly sweeter acidity; use the same amount.
unsweetened coconut water → Cold water or sparkling water. Loses coconut flavor. If using sparkling water, strain the shaken matcha mixture first and top the glasses rather than shaking the bubbles.
fresh mint sprigs → Basil leaf or omit. Garnish only; the drink tastes the same without it.
