For most matcha, start with water around 80°C (175°F). It is hot enough to whisk the powder well without pushing bitterness as much as boiling water can.
What Temperature Should Matcha Water Be?
About 80°C is a good starting point. If your matcha tastes unusually bitter or astringent, try dropping the water to around 70–75°C and compare.
The Easiest Method: Use a Temperature-Controlled Kettle
Set the kettle to 80°C and pour. This is the simplest way to get the same temperature every time.
How Do You Check the Temperature With a Thermometer?
Heat your water normally, then use a kitchen thermometer. Start whisking when the water is around 80°C. You do not need exact precision; being within a few degrees is fine.
What If You Don’t Have a Thermometer?
Boil the water, then let it cool for a few minutes before making your matcha. Pouring the water into another cup or vessel can help it cool faster.
This method is approximate because cooling time changes with the kettle, room temperature and amount of water.
Should You Preheat Your Matcha Bowl?
Yes. Add hot water to the bowl first, swirl it around, then empty and dry the bowl before adding matcha. A cold bowl can cool your measured water more than you expect.
What If Your Matcha Still Tastes Bitter?
Try cooler water before changing everything else. Moving from 80°C down to 70–75°C can soften bitterness in some matchas.

Can You Use Boiling Water for Matcha?
You can, but it is usually not the best choice. Very hot water can make bitterness and astringency more noticeable and make delicate flavours harder to taste.
A Simple Temperature Rule
Start at 80°C. If the matcha tastes too bitter, go cooler. Use a temperature-controlled kettle or thermometer when you want consistency, and treat the exact number as a starting point rather than a strict rule.
