With a normal amount of tea leaves, it's best to Drink the tea within one minute of steeping, with some teas requiring only a few seconds or up to ten seconds before they are ready to be poured, and should not be steeped for too long. By this time, 80% of the caffeine and 60% of other soluble substances have been extracted. If steeped for too long, the tea will become bitter and astringent.

Tea is best brewed in Ceramic pots or cups, not in thermoses. When tea is brewed in a thermos, the tea remains at a high temperature for an extended period of time, causing some of the aromatic oils to evaporate, reducing the aroma; too much tannin and alkaloids are also released, giving the tea a bitter taste, and some nutrients are lost as well, along with the risk of over-steeping the tea.
