What Water Temperature Should You Use for Matcha?

Start with water around 176°F (80°C), keep the matcha amount the same, and taste before changing the temperature.

Your matcha is in the bowl and the water has just boiled: should you pour it right away? To start, we recommend water at around 176°F (80°C). Sift the powder, mix it with a little of that water, then add the rest and taste. This temperature is a starting point, not a rule for every cup.

We prefer to let the water cool after boiling so we can taste the tea's nuances more clearly. Cooler water may suit you too. If you want to revisit the amount and the whisking motion, the matcha preparation method gives the full process around that starting point.

What water temperature should you use for matcha?

Hot water poured from an unmarked kettle into an open pitcher to cool before making matcha.

About 176°F (80°C) is where we'd start for a first hot cup. To find out what temperature changes, keep the same powder and amount. Make one cup, then another with slightly warmer or cooler water. You'll taste the difference without confusing it with a new dose.

We prefer that comparison to an arbitrary setting. Adding more powder could mask the effect of the water.

Can you use boiling water for matcha?

We avoid pouring water straight off the boil onto the powder. High heat can bring out more bitterness and make a delicate cup taste harsher. It doesn't make matcha dangerous or automatically “destroy” its qualities.

Let the water cool before tasting: a scalded palate can't judge the cup well. If you deliberately want a more intense flavor, compare two otherwise identical preparations and change only the water. If bitterness remains, the causes of bitter matcha go beyond temperature.

How can you approach 176°F (80°C) without a thermometer?

An adjustable kettle lets you choose the temperature. Without one or a thermometer, pour boiled water into an open vessel and let it cool before making the matcha. The time depends on the amount of water and the vessel: a fixed waiting time would be misleading.

To compare several trials precisely, we'd use a thermometer. For an everyday cup, the same vessel and your own taste may be enough. Keep the method consistent first, and you'll better understand what you changed.

What water should you use for matcha?

We like soft water with few minerals, which lets you taste the tea without taking over. But drinking water you enjoy is still a good starting point. Change the water only after trying the same powder at the same temperature, or you won't know which variable mattered.

A cup that seems flat or harsh isn't always explained by heat. Water, amount, and powder matter too. Sorting out those differences matters less in a very milky or sweetened drink, where other flavors take more space.

Can you prepare matcha with cold water?

Clear water poured from a carafe into a transparent shaker on a wooden table.

Yes. Cold water gives a different sensation and calls for thorough mixing to disperse the powder. This cup isn't a substitute for one made at 176°F (80°C) if you're comparing a hot usucha, a lighter matcha prepared with water.

Even when making it cold, we'd start with a little water before filling the bowl. Clumps break up more easily. With a closed shaker and cold water, that step may be unnecessary.
