Plus the Top 10 Thermometer Finds on Amazon

Drinking a good-tasting green tea is great for our mind and body. We surely do not want to drink a cloud of bitter tea dust or a too-soaked tea bag in a cup! Experience the calm environment of tea-time by knowing how to make the most out of your tea leaves; plus the best thermometers for your tea on Amazon.

How Much Green Tea and How Hot Should It Be?

First, don’t use boiling water, because it’s too hot to drink and your tea might end up with a bitter or burnt-leaf taste. After boiling water, let it cool until it reaches the proper water temperature.

We must determine the suitable water-to-tea-leaves ratio by knowing how much water your teapot can hold. When measuring tea leaves, it is best to do it in grams instead of teaspoons because there are different types of Japanese green tea leaves, and they are in different shapes and sizes – unless the tea leaves you bought have instructions. In most teas, there must be 2 grams of leaves for every 6 ounces of hot water. If you do not have a food scale, measure out 1-2 teaspoons of green tea, add hot water, and taste the green tea to your liking.

The usual water temperature for green tea is 160°F to 176°F or 72 °C to 80°C, but for other Japanese green teas, here are their standard serving size and temperature to enjoy them:


8 grams or 3 teaspoons – 250ml water (the usual single-cup serving) – 122 to 140°F – 2 to 3 minute steeping time.


4 grams or 2 teaspoons – 250ml water –  194°F to 196°F – 30-second steeping time in a kyusu pot or any small teapot.

How Long Do We Have to Steep It in General?

For every 2 grams of tea leaves in a small teapot, the steeping time is 1 to 3 minutes.
