While it may be called in a different name in China, black tea in the world’s most populous country and the rest of the world shares similar health benefits and can go through the same step of making in order to get a good cup.

Definition of black tea

Black tea is a kind of tea that tastes usually stronger than other types of tea like green tea, partly because it contains more caffeine. The name ‘red tea’, as it is called in China, is derived from the water color of the tea, which is popular in East Asian countries and some other parts of the world. Note there is another kind of tea also called ‘red tea’ containing Rooibos leaves. Calling it ‘red’ may be a better description of the color of the drink.

Tips on making a cup of black tea

There are three factors important to the black tea brewing process: water temperature, the amount of tea and tea brewing time.

Water temperature

Brewing tea requires hot water, but each tea needs a specific temperature. Medium boiled water is only suitable for black or old oolong tea. High temperature is needed to break down the texture and spread the flavor. But cooler water is used for delicate teas, like green tea and oolong tea.

Too hot water will "burn" the tea, making it bitter while losing its delicate flavor. Too cold water will also weaken the taste of tea because tea compounds are insoluble.

Amount of black tea

Too much tea is going to make it too bitter while too little tea weakens the taste. Depending on the type of tea, there will be different quantities. One ratio to try is 8 grams for a 300-ml kettle. Then the amount of tea can be adjusted for the best taste.

Brewing time

The cavalry in making tea is "soaked" tea, but this is an error the most people make. It will make the tea too bitter and smell strong. As the water temperature and each type of tea is suitable for a certain brewing time. Black tea and oolong tea can soak longer, while green tea requires a much shorter time. In general, the brewing time is measured by seconds, not minutes.
