How to make really good matcha in a busy café

Matcha has a reputation for being fiddly. There is a bamboo whisk, a bowl, a sieve, a temperature to remember, and a powder that seems determined to find the one dry corner you missed.

Then there is café reality. The docket printer is going, someone wants an oat flat white, someone else wants their matcha iced with strawberry, and nobody has three peaceful minutes to contemplate the tea.

The good news is that proper café matcha sits very comfortably between those two worlds. You can borrow the parts of traditional preparation that genuinely improve the drink, then turn them into a fast, repeatable café recipe.

For us, that comes down to three things: use enough matcha for the amount of milk, keep the water below boiling, and disperse the powder properly before you add the milk.

That is really the whole system.

The rule
For a milk-based matcha, start with roughly 3g matcha per 100ml milk.

For our 250ml matcha flat white, that works out at 6g matcha with around 200ml milk, plus a small 30ml matcha shot.

That ratio is not wildly out of step with Japanese tea houses either. Ippodo’s matcha latte recipe uses 3g matcha with 100ml milk. Ippodo Tea The difference is that we use much less water because we want a concentrated café-style matcha shot rather than a larger tea base.

Barista guide to making a matcha flat white

What you will need

matcha bowl • chasen • measuring teaspoon • tea sieve • thermometer • milk jug for steaming

Method

	Start with a dry bowl Water left in the bowl can make the powder clump.
	Measure 6g matcha powder Weigh 6g, or use approx. 2 level measuring teaspoons.
	Sift matcha powder into the bowl Push it through a sieve with the back of a spoon.
	Get 30ml of hot water at 70-80°C. Mix approximately 20ml boiling water from the machine with 10ml cold tap water. Aim for 70-80°C and use a thermometer to check. A Boiling water can turn matcha bitter.
	Pour the water over the matcha powder. Pour slowly to form a thick, creamy shot.
	Whisk for 15 to 20 seconds. Wet your chasen. Whisk the matcha and water briskly. Hold the chasen lightly and whisk from the wrist in a quick M motion. Stop when the matcha is smooth and glossy, with no clumps.
	Pour the matcha shot into a cup. Tip it from the bowl into the 250ml flat white cup.
	Steam about 200ml cold milk. Texture the milk silky, as you would for a flat white.
	Pour and finish. Add the milk to the shot and create your latte art.

First, stop thinking of it as a latte

Everyone calls it a matcha latte, and we do too. That is what customers search for and what they expect to see on a menu.

But when we build the drink, we think about it more like a flat white.

A big latte cup creates two problems. You either need substantially more matcha to keep the flavour, which pushes your cost up, or you keep the same dose and end up with a pale drink that mostly tastes of milk.

Neither is particularly clever.

A smaller cup lets the matcha do what it is there to do. You get more flavour, a better colour, a better matcha-to-milk ratio and a drink that still sits at a sensible menu price.

The rule
Match the matcha dose to the milk, not the cup label.

If your finished drink uses 150ml milk, start around 4.5g matcha. If it uses 200ml, start around 6g. If you move to a 300ml cup and fill it with substantially more milk, increase the matcha accordingly rather than stretching the same 6g further and further.

That 3g per 100ml milk ratio is a starting point, not holy scripture. Your matcha, milk choice, cup size and customer preference all affect the final drink, but it gives you a repeatable place to begin.

The water temperature matters more than most cafés think

This is probably the biggest technical difference between a good matcha and a bad one.

Traditional matcha is not made by pouring vigorously boiling water straight onto the powder. Ippodo uses 80°C water for its standard usucha, while Marukyu Koyamaen gives a range of roughly 70–85°C depending on the preparation. Ippodo Tea

There is a flavour reason for that.

Green tea contains catechins, amino acids, caffeine and other compounds that all contribute differently to flavour. Catechins are strongly associated with bitterness and astringency, and extraction changes with brewing conditions, including temperature. Research into green tea brewing consistently shows that temperature alters the balance of extracted compounds and therefore the way the tea tastes. PubMed Central (PMC)

Matcha is slightly different from steeped green tea because you are consuming the whole powdered leaf rather than extracting and discarding the leaf. Even so, the practical lesson remains useful: aggressive heat does not improve the flavour.

For café service, we aim for 70–80°C.

The rule
Hot enough to make a smooth matcha. Not hot enough to punish it.

“But my espresso machine only gives me boiling water”

This is where café instructions often become unnecessarily complicated.

Your espresso machine is not the problem. You just need to know what comes out of it.

One machine might give you water at 90°C-something. Another might behave differently depending on where the water is taken from, how recently the machine has been used and how it has been configured.

So rather than pretending there is one magic dilution ratio for every machine on earth, establish the ratio for yours.

For the Superlatte guide, we use approximately 20ml hot machine water and 10ml cold water as a practical starting point for a 30ml matcha shot. Then we tell you to check it with a thermometer.

If that gives your café 75°C, excellent. If your machine needs 18ml hot and 12ml cold, use that.

Measure it once, write the result into your café recipe, and stop thinking about it.

Cafe shortcut
Calibrate your hot-to-cold water ratio once for your machine, then put that exact ratio on the barista card.

That is a much better system than asking every barista to judge whether the water “seems about right”.

Why only 30ml water?

Because we are not making a bowl of traditional usucha and then adding milk to it. We are building a concentrated matcha base for a café drink.

Traditional recipes commonly use considerably more water. Ippodo uses 2g matcha to 60ml water for usucha, while Marukyu Koyamaen suggests around 1.5g to 70ml. Ippodo Tea

Our milk drink has another 200ml of liquid coming.

If we used a large tea base as well, we would increase the finished volume, dilute the milk texture and move away from the flat-white-style drink we actually want.

So we make what is effectively a matcha shot: enough warm water to disperse the powder properly, but no more than we need.

The rule
Water makes the matcha shot. Milk makes the drink.

The shot should be smooth, glossy and concentrated. The milk does the rest.

Matcha does not dissolve

This is an important point because it explains several of the problems cafés have with it.

Matcha is not an instant drink powder that disappears into liquid. It is extremely finely ground tea leaf held in suspension.

That is why stirring it twice with a spoon and hoping for the best does not work particularly well.

It is also why the sieve and whisk matter.

Sifting breaks apart compacted particles before water hits them. Whisking then disperses those particles through the liquid so that you get an even suspension instead of tiny packets of dry powder floating around the cup.

The rule
Sift first. Whisk second. Milk third.

Changing that order is where a lot of unnecessary trouble starts.

Do you really have to sift it?

For a café trying to serve consistently smooth matcha, we think so.

Matcha powder is exceptionally fine and it compacts easily. Once a dry lump gets wet around the outside, it becomes much harder to break apart.

Sifting removes that problem before it exists.

It takes seconds. More importantly, it saves the barista from spending longer trying to rescue a lumpy shot afterwards.

This is one of those steps that looks like extra work until you remove it.

Then you realise why it was there.

Why use a chasen?

Because it is very good at this particular job.

A bamboo chasen has many fine tines, which move rapidly through a small amount of liquid and disperse the matcha evenly. Traditional matcha makers have had rather a long time to work this out.

Ippodo's standard method calls for a vigorous 15-second whisk in an M-shaped movement. Ippodo Tea That is very close to what we recommend for café service.

The important part is not performing a perfect ceremonial gesture. It is creating rapid back-and-forth movement through the liquid.

The motion comes mainly from the wrist, rather than stirring broad circles around the bowl.

The rule
Think quick zig-zag, not slow stirring.

Why not use a handheld frother?

You can make matcha with one. We simply do not think it is the best default tool for a café that wants a consistently good result.

A handheld frother is designed to spin quickly and incorporate air. Depending on the model, vessel and technique, it can produce a lot of larger bubbles without necessarily dealing particularly well with matcha that was clumped to begin with.

A chasen gives you more control over a shallow, concentrated matcha shot, and fifteen or twenty seconds is hardly an eternity.

There is another operational advantage too. A bamboo whisk does the same thing every day. A cheap handheld frother can behave differently as its batteries fade, its shaft bends or somebody uses it at a different depth.

For home, use whatever makes you happy. Behind a bar, repeatability wins.

Why not steam the matcha with the milk?

Because it solves one job by creating three new ones.

The steam wand is very good at texturing milk. It is not designed to sift matcha, break apart dry pockets of powder or control the temperature of the tea itself.

If you dump matcha directly into the milk jug, you make it harder to see whether the powder has dispersed properly. You can end up with matcha coating the jug, hiding in the milk or sitting in little clumps that only reveal themselves in the customer's cup.

You also lose the temperature control we worked so hard to establish.

We deliberately make the matcha with 70–80°C water and then steam the milk separately. Putting the powder under a steam wand immediately afterwards is not a particularly logical next move.

The rule
Make the matcha properly. Texture the milk properly. Combine them at the end.

Exactly as you would not ask the milk jug to pull your espresso shot, you do not need it to make your matcha.

Milk changes the flavour more than you might expect

Milk does not merely increase volume. It changes the entire perception of the drink.

Fat, protein, sweetness and texture all soften the greener and more bitter edges of matcha. Plant milks bring their own flavour and sweetness too.

That means a matcha that tastes beautifully balanced on its own may seem faint once a large quantity of milk is added.

This is another reason our dose looks high if you compare it directly with traditional straight-matcha recipes.

Traditional usucha may use around 1.5–2g per serving. Marukyu Koyamaen Our 6g dose is designed to stand up to around 200ml of milk.

We are making a different drink.

Why bitterness happens

The easy answer is “bad matcha”, but that is far from the only reason.

Water that is too hot can push the flavour in a harsher direction. Too much matcha for the liquid can make the drink overly intense. Old or poorly stored matcha can lose sweetness and vibrancy. Water composition can make a difference too.

There is interesting research around water hardness and green tea. Mineral content and alkalinity can affect extraction, colour and catechin stability, and studies have found noticeably different sensory results depending on the water used. PubMed Central (PMC)

I would not ask cafés to start performing a water chemistry experiment for every matcha order. But if your matcha consistently looks dull or tastes odd despite a correct recipe, your café's water is worth considering.

Many specialty coffee shops already put a great deal of thought into water quality for espresso. Matcha benefits from good water too.

Useful to know
If the recipe is correct but the matcha still tastes wrong, check the water before blaming the powder.

Straight matcha needs a different ratio

A customer asking for straight matcha is not asking for the milk recipe minus the milk.

Here, a much lighter matcha-to-liquid ratio makes sense.

Our starting recipe would be 3g matcha to 100ml water at around 80°C.

That gives you a fuller café-style straight matcha. If you want to move closer to traditional usucha, benchmark it against recipes such as Ippodo's 2g to 60ml or Marukyu Koyamaen's roughly 1.5g to 70ml. Ippodo Tea

The useful operational point is simply to have two recipes.

One for milk.

One for water.

Do not expect one matcha ratio to do both jobs.

Iced matcha follows the same rules

Cold milk does not magically make dry matcha easier to disperse.

If anything, trying to mix matcha directly into an icy drink makes your life harder.

Make the concentrated matcha shot first with warm water, then build the cold drink around it.

Ippodo follows the same general logic for its iced matcha recipes: prepare the matcha with hot water first, then cool or add milk and ice. Ippodo Tea

The rule
Hot or iced, make the matcha first.

That one rule gives you a much more consistent drinks menu.

Matcha speed comes from setup, not shortcuts

This is where I think we can speak directly to café owners without ever implying that their baristas are doing anything badly.

Matcha gets slow when the method has never been designed for service.

The sieve lives on another shelf. Nobody knows where the scale went. The whisk is sitting in a sink. One person uses a teaspoon and another uses the bamboo scoop. Nobody knows exactly how much water should go in.

That is a workflow problem, not a matcha problem.

Put everything together.

Matcha. Bowl. Chasen. Chasen stand. Sieve. Portion measure or scale. Thermometer.

Then train one recipe.

Once the barista can reach for everything without moving around the bar, a fifteen-second whisk stops feeling like a production.

Cafe shortcut
Build a matcha station, not a matcha scavenger hunt.

The useful numbers to remember

This could become one of your strongest visual panels because it gives owners a little framework rather than just a recipe.

For Superlatte café service:

3g matcha per 100ml milk

30ml water for the matcha shot

70–80°C water

15–20 seconds whisking

Around 200ml milk for a 250ml matcha flat white

Those five numbers answer most of the drink.

Everything else is technique.

And this is where tradition still matters

There is a temptation to frame traditional preparation and busy café service as opposites.

They do not need to be.

Traditional matcha preparation has already solved several of the problems cafés encounter: how to deal with finely ground tea, how to prevent clumps, what sort of whisk works, how much heat is appropriate and how to create a smooth suspension.

We borrow those answers.

Then we make a flat white with them.

There is obviously no ancient Japanese rule saying “serve 6g of matcha with 200ml oat milk and finish with a tulip”.

We are comfortable with that.

The point is not to turn a commercial café into a tea ceremony. It is to understand which parts of the traditional method protect the quality of the matcha, and keep those bits.

That is the balance we are after.
