The reason black tea traditionally requires a higher temperature than green teas is that black teas are more oxidised and are therefore more stable. In order to bring out the tannins, water of a higher temperature is needed; however, if the brewing occurs for a long period of time then a high concentration of tannins can dominate the flavor, causing bitterness. On the other hand, if a delicate leaf is steeped in water that is of too high a temperature, the leaves will burn, as well as extract more from the tea leaves due to the higher molecular energy, creating too many acids and leaving a bitter flavour in the cup.
Yet, the temperature of tea is actually largely due to personal choice. In fact, you can still brew delicate teas such as white teas at a higher temperature or, conversely, black teas at a lower one. A good rule of thumb is ‘the hotter you brew, the darker and more robust your tea will be; the cooler your water, the sweeter and more mild it will taste.’ As long as you drink good quality leaves, every cup should taste wonderful.
