Key Takeaway

• Gather matcha, cold brew or espresso, milk (or plant milk), ice, and sweetener.

• Whisk matcha into a smooth slurry first.

• Fill your glass with coffee, milk, and ice.

• Add matcha and stir (or layer for a prettier look).

• Sweeten to taste and enjoy.

Essential ingredients and ratios for How to Make an Iced Matcha Coffee Drink at Home

To make this drink at home you need five things: matcha powder, espresso or strong coffee, milk (or milk alternative), ice, and an optional sweetener. Use fresh, bright-green matcha; a double shot of espresso (60 ml) or 60–90 ml strong coffee; and 150–200 ml cold milk. Ratios to start with per cup:

• Matcha: 1.5–2 g (≈1 rounded tsp)

• Espresso/strong coffee: 60 ml (double shot)

• Milk: 150–200 ml

• Ice: 4–6 cubes

Small tweaks change the drink: increase matcha for tea-forward, increase espresso for coffee-forward, or add milk to soften bitterness. Simple syrup (5–10 ml) dissolves best in cold drinks.

Best matcha for iced coffee and how to pick it

• Ceremonial matcha: smoother, slightly sweeter, best for a delicate green-tea note.

• Culinary matcha: made for mixing, better value, holds color with milk and sweeteners.
  Look for vibrant green, fine texture, and a fresh vegetal aroma. Finer powder mixes more easily and clumps less with cold water. For guidance on grade, color, and texture, see How to choose quality matcha powder.

How much matcha, espresso, and milk per cup

For a single iced cup:

• Matcha: 1.5–2 g (≈1 rounded tsp)

• Espresso: 60 ml (double) — or 30–90 ml depending on coffee strength desired

• Milk: 150–200 ml

• Ice: 4–6 cubes

Adjust: 2.5 g matcha for matcha-forward; 90 ml espresso for coffee-forward. Dissolve matcha into a small amount of water first (slurry), then add espresso, milk, and ice. Taste and tweak. For espresso volume and extraction standards see Guidelines for espresso shots and extraction.

Serving size	Matcha (g)	Matcha (tsp)	Espresso	Milk (ml)
Single (balanced)	1.5–2.0	~1 rounded tsp	60 ml (double)	150–200
Strong matcha	2.5	~1.5 tsp	60 ml	150
Strong coffee	1.5	~1 rounded tsp	90 ml	120–150

Tools and prep for your homemade matcha coffee

Essential tools:

• Fine mesh sifter (optional)

• Small whisk (bamboo or electric frother) or shaker/blender

• Measuring spoon or scale

• Glass or cup

Prep: sift matcha, make a slurry (1 tsp matcha 20–30 ml water), chill coffee/espresso, and have milk and ice ready. Use chilled espresso or cold brew to avoid fast dilution; chilled espresso ice cubes are a useful trick. Learn traditional whisking techniques at Traditional matcha preparation and whisking techniques.

Whisk, shaker, or blender: which works best

• Bamboo whisk: classic texture, medium froth, quiet, minimal cleanup.

• Shaker/jar: fast for iced matcha, portable, low-medium froth.

• Blender: frothy, great for frappes or smoothies, louder, more cleanup.

Tool	Best for	Froth	Cleanup
Bamboo whisk	Hot matcha, ritual	Medium	Rinse & air-dry
Shaker/jar	Quick iced matcha	Low–Medium	Rinse & dry
Blender	Iced frappes, mix-ins	High	Disassemble & wash

Cold water, ice, and milk temps

Cold water dissolves matcha more slowly—make a small slurry or use a shaker for 20–30 seconds. Alternatively dissolve in a splash of warm (not boiling) water then cool with ice for fewer clumps. Use chilled coffee/espresso. Milk choices:

• Whole milk: creamiest mouthfeel.

• Oat milk: naturally sweet, foams well.

• Almond milk: thinner, may separate more.
  Add ice last and pour milk over ice to help keep layers and prevent excessive dilution.

Tip: Make a matcha slurry (1 tsp matcha 1–2 tbsp water) and chill it while you brew coffee—fewer clumps, faster assembly.

Cleaning and storing your tools to keep flavors pure

Rinse and dry tools immediately. Rinse bamboo whisks with warm water only; store upright. Clean glass shakers and blender parts with warm soapy water and dry thoroughly. Keep matcha sealed in an airtight tin in a cool, dark place; store coffee separately. Follow official recommendations for refrigeration and storage times: Safe refrigeration and storage time guidance.

A simple iced matcha coffee recipe you can follow

This recipe shows How to Make an Iced Matcha Coffee Drink at Home—bright, layered, and refreshing.

Ingredients (one cup)

• Matcha powder: 1 tsp (about 2 g)

• Hot water (to dissolve matcha): 2 tbsp (30 ml)

• Coffee or espresso (chilled): 3–4 oz (90–120 ml)

• Milk or milk alternative: 3–4 oz (90–120 ml)

• Ice: as needed

• Sweetener (optional): 1 tsp simple syrup or to taste

Step-by-step iced matcha coffee recipe for one cup

• Sift and measure matcha; add 30 ml hot (not boiling) water. Whisk until smooth and frothy.

• Fill a glass with ice. Pour chilled coffee or espresso over ice.

• Add milk.

• Slowly pour the dissolved matcha over the back of a spoon or down the glass side for layers, or stir to combine.

• Sweeten to taste and serve.

Tip: No bamboo whisk? Use a small electric frother or shake matcha and water in a sealed jar for 15–20 seconds.

Layering matcha and coffee for a pretty drink

Layering depends on density and slow pouring. Typical approach:

• Pour milk first (densest), then coffee, then matcha last for a green top.

• For inverted look, place matcha first and pour coffee over a spoon to create bands.
  Serve in a clear glass so the stripes show. Make the green mix slightly thicker (extra pinch of matcha) for a stronger visual and taste presence.

Variations and ratios: iced matcha latte with espresso

Matcha and espresso can be layered, shaken, or blended. A balanced iced matcha latte ratio:

• 1 tsp (≈2 g) matcha 30–45 ml hot water

• 1 shot espresso (30 ml)

• 180–240 ml milk over ice

Adjust for style:

• Coffee-forward: 2 shots espresso, less milk (120–150 ml).

• Matcha-forward: 1.5–2 tsp matcha.
  Shake to blend flavors, or layer to keep them distinct.

Style	Matcha	Hot water	Espresso	Milk
Balanced	1 tsp (2 g)	30–45 ml	1 shot (30 ml)	180–240 ml
Coffee-forward	1 tsp	30 ml	2 shots (60 ml)	120–150 ml
Matcha-forward	1.5–2 tsp	45 ml	1 shot	180–240 ml

Vegan swaps for plant milk and sweeteners

Plant milk options:

• Oat milk: creamy and foams well.

• Almond milk: lighter, lets flavors shine.

• Coconut milk: tropical note.

• Soy milk: neutral and fuller mouthfeel.

Sweetener options:

• Simple syrup: best for cold mixing.

• Maple syrup: warm, pairs well with matcha.

• Agave: neutral and vegan-friendly.

• Honey: floral (not vegan).
  For low-calorie, try stevia or erythritol; test first as they can taste different.

Cold foam, syrups, or citrus: top with oat cold foam, add vanilla or caramel syrup for dessert vibes, or use citrus zest (orange or lemon) to brighten flavors. Dust a little matcha on top for color. For a breakdown of plant milk choices and their properties, see Comparing plant milks for texture and nutrition.

Sweeteners and flavor add-ins

• Dissolve granulated sugar first (hot water) or use simple syrup for cold drinks.

• Vanilla rounds bitterness; start light.

• Cinnamon pairs well with milkier drinks.

• Citrus (lemon or orange peel) brightens the drink.

Tip: Blend briefly with ice to dissolve sweeteners and get a slushy texture.

Troubleshooting, storage, and serving tips for How to Make an Iced Matcha Coffee Drink at Home

Common fixes:

• Flat taste: boost matcha by 1/4 tsp or use a bolder coffee.

• Gritty matcha: make a slurry and whisk briskly or sift the powder before mixing.

• Separation/cloudiness: ensure matcha is dissolved before adding cold liquids and add ice last.

Why matcha clumps: powder meets water unevenly. Fix by whisking matcha with 1–2 tbsp water to a paste, or sift the powder. For persistent clumps, use slightly warm (body temp) water, then cool the paste before adding ice.

Storage:

• Matcha: sealed tin in a dark cupboard (opened: best 1–3 months). Avoid repeated fridge in-and-out.

• Cold brew: airtight bottle, chilled (2–3 days).

• Espresso shots: airtight container, chilled (12–24 hours).

Item	Storage method	Best use time (fridge)
Opened matcha	Sealed tin, dark cupboard	1–3 months
Unopened matcha tin	Fridge or cool cupboard	6–12 months
Cold brew concentrate	Airtight bottle, chilled	2–3 days
Espresso shots	Airtight container, chilled	12–24 hours

Serving tips:

• Add ice last to avoid over-dilution during assembly.

• Offer simple syrups on the side for guest customization.

• Use clear short glasses to show layers; a straw helps stir without breaking foam.
