How do I brew longjing tea? [closed]

Brewing method is pretty standard, like most green teas: 80 deg Celsius, let it steep for a few minutes.

Longjing tea is a green tea. So the general principals of brewing green tea apply:

The tea leaf to water ratio: Around 3 g of tea leaves for 150ml of water.

Water temperature is very important to bring out the best in a green tea. Not sure if you've had green tea before, but if the water temperature is too hot or boiling, the tea will brewed bitter and will lose much of its delicate aroma. On the other hand, if it not hot enough, the brewed tea will not be full flavored.

For the first and second steeping, the tea leaves should be brewed in hot water at 70°c - 80°c for 1 minute. You can always experiment with the length to find out your desired flavor.

For subsequent brewing, if reusing the same leaves, increase steeping time and temperature.

Notes, the easiest way I personally find to reach this desired temperature (75°c), at least in a cup, is to fill 3/4th cup with hot water and 1/4th with cold water, a tip shared by a tea shop employee.
