Using a Coffee Machine to Prepare Matcha

What to check first
Brewer type and filter type
Your coffee machine is built for coffee grounds and paper or metal filters. Matcha is a fine powder. It’s going to clog filters and make a mess. Some machines might have a hot water dispenser, but that’s about it.
Water quality and temperature
Good water makes good matcha. If your coffee machine’s water tastes off, so will your matcha. For matcha, you want hot, but not boiling, water. Around 175°F is the sweet spot. Most coffee makers brew hotter, which can scorch the matcha.
Grind size and coffee freshness
This rule is for coffee, but it highlights the difference. Matcha isn’t “ground” like coffee beans. It’s stone-ground into a superfine powder. Freshness matters for both, but the particle size is key here.
Coffee-to-water ratio
The standard ratio for coffee is about 1:15 to 1:18 (coffee to water). Matcha is typically prepared with a much higher concentration of powder to water. Trying to replicate coffee ratios with matcha powder will yield a very weak, watery drink.
Cleanliness/descale status
If your coffee machine is grimy or needs descaling, you definitely don’t want that residue in your matcha. A clean machine is important for any beverage.
Step-by-step (brew workflow) – The Coffee Machine Way (Not Recommended)
1. Fill the water reservoir: Use fresh, filtered water.
- Good looks like: A clean reservoir filled to the desired level.
- Common mistake: Using old water or not filling enough. Avoid this by always starting with fresh water.
2. Place a filter in the basket: Use a clean paper filter.
- Good looks like: A correctly seated filter, ready for grounds.
- Common mistake: Forgetting the filter or using a ripped one. Double-check it’s there and intact.
3. Add coffee grounds (optional): This is where it goes wrong. You don’t add coffee grounds if you’re trying to make matcha.
- Good looks like: An empty brew basket, ready for something else.
- Common mistake: Adding coffee grounds out of habit. Resist the urge!
4. Add matcha powder to the filter: This is a bad idea, but if you’re determined…
- Good looks like: The powder sitting in the filter. It won’t look good for long.
- Common mistake: Putting too much powder, causing a clog. Start with a tiny amount, like a teaspoon.
5. Start the brew cycle: Let the machine heat and dispense water.
- Good looks like: Water flowing through the grounds (or powder).
- Common mistake: The water not flowing, or flowing too fast. This is likely to happen with matcha.
6. Observe the drip: Watch the liquid collect in the carafe.
- Good looks like: A smooth, steady drip.
- Common mistake: The filter clogging and overflowing. If it backs up, stop the machine immediately.
7. Pour and inspect: Pour the resulting liquid into a mug.
- Good looks like: A green-ish liquid.
- Common mistake: It’s clumpy, gritty, and possibly lukewarm. Expect this.
8. Attempt to whisk: You’ll need a whisk anyway to try and break up clumps.
- Good looks like: Smoother liquid after whisking.
- Common mistake: The powder won’t fully dissolve, leaving sediment. You’ll still have grit.
Common mistakes (and what happens if you ignore them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using a coffee machine for matcha | Gritty, unevenly mixed, potentially scorched drink. | Use a separate kettle and whisk. |
| Not using filtered water | Off-flavors in your matcha. | Always use fresh, filtered water for any hot beverage. |
| Water too hot (over 175°F) | Bitter, “cooked” taste in the matcha. | Use a thermometer or let a boiled kettle sit for a minute before pouring. |
| Using too much matcha powder | Clumps and a difficult-to-dissolve paste. | Start with a small amount (1-2 tsp) and add water gradually. |
| Not sifting matcha powder | Large clumps that won’t break down. | Sift your matcha through a fine-mesh sieve before adding water. |
| Not whisking properly (using a whisk) | Sediment at the bottom of the bowl. | Whisk vigorously in a “W” or “M” motion until frothy. |
| Using the wrong kind of matcha | Poor flavor and texture (e.g., culinary grade). | Use ceremonial grade matcha for drinking straight. |
| Not cleaning your equipment | Stale flavors and potential mold growth. | Wash your whisk and bowl immediately after use. |
| Adding sugar/milk too early | Clumps can form more easily. | Dissolve the matcha in water first, then add sweeteners or milk. |
| Storing matcha improperly | Loss of vibrant color and flavor. | Keep matcha in an airtight container in the fridge or a cool, dark place. |
Decision rules (simple if/then)
- If you want authentic, smooth matcha, then do not use a coffee machine because it’s not designed for powders.
- If you have a coffee machine with a hot water dispenser, then you can use it for hot water, but you still need to whisk the matcha separately.
- If your coffee machine only brews coffee, then it has no function that can help you make matcha.
- If you are in a hurry and only have a coffee maker, then accept that your matcha will likely be subpar.
- If you have a separate kettle and a bamboo whisk (chasen), then you are set up to make great matcha.
- If your matcha tastes bitter, then your water was likely too hot, or you used low-quality matcha.
- If you see lots of clumps, then you either didn’t sift the matcha or didn’t whisk it enough.
- If you want to make a matcha latte, then prepare the matcha first, then add steamed milk.
- If you are experimenting, then try using the hot water dispenser only and whisking in a separate bowl.
- If you value taste and texture, then invest in the proper tools for matcha preparation.
FAQ
Can I just put matcha powder in my coffee maker’s filter basket?
Technically, you can try, but it’s a bad idea. The fine powder will likely clog the filter and not dissolve properly, leaving you with a gritty, weak drink.
Will my coffee maker heat the water to the right temperature for matcha?
Probably not. Most coffee makers brew water much hotter than the ideal 175°F for matcha. This high heat can scorch the delicate powder, making it taste bitter.
What’s the best way to make matcha if I don’t have a fancy tea ceremony set?
You just need a bowl, a whisk (a bamboo chasen is best, but a small regular whisk can work in a pinch), and a way to heat water to the right temperature, like a stovetop kettle or a variable temperature electric kettle.
While not strictly necessary, a traditional matcha bowl can enhance the whisking process and overall enjoyment. Consider adding a beautiful matcha bowl to your collection for a more authentic experience.

Is it okay to use culinary grade matcha for this?
Culinary grade matcha is usually best for baking or lattes where other flavors are present. For drinking straight, ceremonial grade is recommended for its smoother flavor and vibrant color.
What if I have a coffee maker with a hot water dispenser?
That’s your best bet with a coffee maker. You can use it to dispense hot water into a separate bowl, then whisk your sifted matcha powder into that water. It’s still not ideal, but better than brewing it through the coffee filter.
Why is my matcha always clumpy?
Clumps happen when the matcha powder isn’t sifted before adding water or when it’s not whisked vigorously enough. Sifting and a good whisking motion are key.
Can I add milk and sugar directly to the coffee maker with the matcha?
Absolutely not. Never put anything other than water in your coffee maker’s reservoir or brew basket, except for coffee grounds.
How much matcha powder should I use?
A good starting point for a traditional bowl of matcha is 1-2 teaspoons of powder per 2-3 ounces of water. Adjust to your taste.
