If you've ever found matcha a little too grassy or bitter, cold brew matcha might change your mind entirely. It's the gentlest way to prepare matcha — no hot water, no whisking technique to master, and a flavour that's noticeably smoother and sweeter than the traditional hot preparation. All you need is good matcha, cold water, and a jar with a lid.
What Is Cold Brew Matcha?
Cold brew matcha is exactly what it sounds like: matcha powder mixed into cold water and shaken or stirred until fully combined. Unlike loose leaf tea, matcha doesn't need to steep — the powder is the tea, so it dissolves (technically, suspends) instantly in any temperature of water.
The magic is in what cold water doesn't do. Hot water extracts more catechins, the compounds responsible for matcha's astringent, slightly bitter edge. Cold water keeps those in check while letting the natural sweetness and umami — driven by the amino acid L-theanine — come forward. The result is a mellower, rounder cup that tastes almost creamy on its own.
Why Cold Brew Matcha Works So Well
- No bitterness. Cold water never scalds the leaf powder, so even people who find hot matcha intense tend to enjoy it cold.
- No equipment needed. A jam jar or drink bottle with a tight lid does the job. No whisk required.
- Same gentle caffeine. You still get matcha's steady, focused energy — the caffeine content doesn't depend on water temperature.
- Make-ahead friendly. Shake up a batch in the morning and it's ready whenever you are.
How to Make Cold Brew Matcha (Step by Step)
What you'll need
- 1–2 teaspoons (2–4g) of ceremonial grade matcha
- 250–300ml cold filtered water
- A jar or bottle with a tight-fitting lid
- Ice, to serve (optional)
Quality matters more with cold brew than almost any other preparation, because there's nothing to hide behind — no milk, no sweetener, no heat. A ceremonial grade matcha like Meiso Ceremonial Matcha gives you that vivid green colour and naturally smooth, umami-rich flavour that makes cold brew shine.
The method
- Step 1: Add your matcha to the jar first, then pour in a small splash of cold water (about 30ml). Seal and shake hard for 10 seconds. This creates a smooth paste-like base and prevents clumps.
- Step 2: Add the remaining cold water, seal again, and shake for another 15–20 seconds until the liquid is uniformly green with a light froth on top.
- Step 3: Pour over ice and drink, or refrigerate for up to 24 hours. Give it a quick shake before drinking, as matcha naturally settles.
That's it. Two shakes and you're done.
Tips for Better Cold Brew Matcha
- Sift if you're stirring instead of shaking. Shaking in a sealed jar breaks up clumps on its own, but if you're mixing in an open glass, sift the matcha first.
- Start with less powder. Cold brew tastes smoother, so 1 teaspoon per 300ml is plenty for most people. Scale up once you know your preference.
- Use cold, filtered water. Chlorinated tap water can flatten matcha's delicate flavour.
- Drink it within a day. Matcha oxidises over time, and both the colour and freshness fade after 24 hours in the fridge.
Easy Variations to Try
- Cold brew matcha latte: Make a concentrated cold brew (2 teaspoons in 100ml water), then top with cold milk of your choice over ice.
- Sparkling matcha: Shake your matcha with 50ml of still water first, then top with chilled sparkling water and a squeeze of lime. Surprisingly refreshing.
- Honey citrus matcha: Add a teaspoon of honey and a strip of orange peel to the jar before shaking.
- Coconut cold brew: Swap half the water for chilled coconut water for natural sweetness and a tropical edge.
Cold Brew vs Traditional Hot Matcha
Neither is better — they're different moods. Traditional hot matcha, whisked in a bowl, is a ritual: warming, meditative, and full-flavoured. If you love that ceremony, a proper bamboo matcha whisk and chawan bowl make it a genuine pleasure. Cold brew is the everyday workhorse: fast, forgiving, and perfect for warmer days or busy mornings when you want your matcha without the setup.
Many matcha drinkers end up doing both — hot whisked matcha on slow mornings, cold brew shaken in a jar on the way out the door.
