Heralded as a great healer, green tea has been a popular drink in Asia for hundreds of years. If you are new to green tea, I suggest that you try a few different kinds, as each one has a distinctive taste. Brew tea with cooler than boiling water. If you find that it is bitter, your water may have been too hot. I recommend re-infusing green tea a number of times, paying attention to the subtle changes in taste.
