Correct water temperature for sencha?

How are you doing today, everyone?

How do you usually cool down boiling water to the correct temperature for green tea? Do you use a water cooler (pitcher) or cups and a teapot?

I usually use a big mug for sencha (most common Japanese green tea) when I’m working at office. The teapot and mug in the picture are what I’m using now. When I was preparing sencha this morning, I was curious if I’m always using right temperature water for the tea. I usually pour boiling water into the empty teapot, and then pour the hot water from the teapot into the mug. I use the hot water in the mug to brew sencha. In this way I can usually make delicious sencha pretty much. But I’ve never measured the actual temperature of the water.

So, let’s check it out!
I did measured the temperature today.

Boiling water → Teapot → Mug = Temperature???

**Conditions**
Amount of boiling water : About 500ml
Room temperature : 21 degrees C
Experimental tool : Mug(500ml) and Teapot (550ml) in the picture, and a thermometer

How much do you guess the water temperature was?
I’ll tell you the result at my next blog, talked you soon!!
