First, experts recommend using cold water. For one, they say hot water out of the tap can contain impurities that cold water does not. Also, using cold water ensures that it has been well aerated which allows the full flavor of the tea to be released. In the event of poor tap water, it is recommended that filtered or bottled water be used instead. Next, bring the water to a rolling boil, making sure to not over boil. Then pour the water over a tea bag or teas leaves in cup. Steeping is generally between 3 and 5 minutes. Different types of tea require different brewing times so check the package instructions carefully to guarantee the correct flavor.
