Green tea was originated from China during the reign of Emperor Shennong. Over the centuries, green tea has been Asia’s all-time-favourite. While it is calming and relaxing drinking green tea, there are also lots of health benefits drinking it. Proper technique is very important when making green tea. Water temperature cannot be too hot. Boiling water will burn the leaf and cause bitterness. Green tea does not require much time to steep. Over-steeping will also result in bitterness and a less balanced flavor.
