How to Brew

Start with fresh water
Most black teas recommend you bring the water to a boil
Choose the correct amount of tea for you application. Most teas will have a recommendation of how much loose tea or how many tea bags to use.
Allow the black tea to steep / brew for 3-5 minutes. Your specific tea may come with a recommendation for this as well.
Let the tea cool for a few minutes and enjoy

A few other tips are trying not to oversteep your tea. This can make for a bitter taste. One more tip, if you are using loose tea, is to give the loose tea room to expand.
