With Mellow Monk, you can come pretty close to perfection in green tea. But seriously, folks, the same philosophy that's behind what these therapists are talking about also applies when brewing tea: You don't need to get overly fussy about water temperature or the amount of tea leaves you use.

Tea time is supposed to be a time for relaxation. Instead of striving for perfection, think of every cup of tea you brew as a learning experience. Brewing green tea is an art, not a science, and the goal is to strive for what you think is the perfect cup of tea, not what someone else says is perfect.
