good tea does not come prepackaged in ready to serve bags.
you'd have to hit up chinatown or chinese markets for the real deal. but then u'd have to know what to look for also without getting ripped off of the generic stuff.
i drink it almost every night. my parents are hardcore tea enthusiasts and drinkers. they get the real deal from china and hong kong everytime they go.
black tea, red tea and some green tea is the best.
