One of them is the leaf, because the younger they are, the more caffeine they have, because it is the way to protect themselves from insects. Other factors that influence the caffeine content are: the age of the plant, the terrain, the climate, etc.
On the other hand, it is also important to take into account the way the tea is made, for example, if it is infused cold it has less caffeine than when it is brewed in boiling water. Roughly speaking, the average caffeine in green tea is one third of that contained in coffee in the same volume.

Black tea tops the list of teas with the highest amount of caffeine. Several references indicate that in every 100 gr of tea there is between 20 and 100 mg of caffeine, as we mentioned, depending on certain factors. For example, in a cup of black tea (237 mg) contains between 25 and 48 mg of caffeine. The temperature to prepare it should range from 80° to 90° C for about 3 to 4 minutes.
To know what the caffeine in green tea is , matcha is a variety of green tea, it could be said that the amount of caffeine it has is less than black tea. However, it is not true. For example, the tea used in the Japanese ceremony consists of crushed whole leaves. When this matcha tea is drunk, the powder that remains once crushed is drunk, in this way it is more concentrated than the one that comes in bags. One tablespoon of black tea contains approximately 68 mg of caffeine. In the same amount, but of green tea there is 32 mg of caffeine.

Green tea is very popular for its effects on weight reduction. To find out how much caffeine the green tea has, it can be established as an average (between 25 and 28 mg per 100 grams of tea). In its preparation, young tea leaves are used, which are then subjected to a minimal oxidation process that generates a moderate amount of caffeine in relation to the previous ones.
White tea is the one with the least oxidation, it has less caffeine than the previous varieties. In this sense, some researchers indicate that the amount of caffeine is less than 1 mg.
Pu Erh Tea
Also called red tea, it contains the same amount of caffeine as white tea, because it is another of the teas that is not as oxidized. However, to obtain its particular flavor and color it goes through a fermentation process. Although the evidence still does not certify that it is so.
