DOES BLACK TEA HAVE CAFFEINE?

Black tea is the most prevalent of all types of tea. It is said that it was discovered by Chinese and then it was extended worldwide for its beneficial properties. As other types we can highlight the oolong tea, white tea, and not least, the green one. All this teas are different in nature, color, flavor, taste and the list may go on. The black tea is usually more oxidized than the others and seems to have the stronger and the most durable flavor. These teas are all made from the leaves of Camellia sinensis, a small shrub tree, but the most important thing that makes them different is the time required for oxidation process.

Because it is completely oxidized, the black one is strongest than others and it can be kept longer without to lose his flavor. His name is coming from the leaves color after the fermentation process which are changed in black. Now let’s see some caffeine informations.

 

BLACK TEA VS COOFEE

In both, coffee and tea, caffeine is a naturally occurring pesticide that can be found in their content. Before the tea leaves to be brewed, the caffeine content is higher than coffee. Also, more of it can be found in the leaves of the camellia sinensis, the plant from which it is processed, than can be found in the beans of the coffea Arabica plant. But due the process of creating tea from these leaves, the roles are reversed when we have the final product.

Coffee is a stronger beverage than tea and after it has been brewed, a cup of coffee possesses more caffeine than a cup of tea. This can be simply noticed through a trick. Take a look at a cup of tea and a cup of coffee. You’d have a harder time seeing through a cup of coffee than you would ever have seeing through a cup of black tea. One of the reasons is that the content of coffee beans from a cup is higher than leaves and this it appears to influence the caffeine content.

 

GREEN TEA AND BLACK TEA

The Camellia sinensis which is the shrub from which Black tea is processed is also the same plant from which the green one is equally processed. The slight difference here which change the whole scenery is in the picking, fermentation and oxidation process. The amount of caffeine from the green one is smaller than the one from black tea. This is due to the oxidation process. While green tea usually loses its flavor after a year, black tea still retains its own flavor after years.

 

WHITE TEA AND BLACK TEA

The white teas are picked when the young tea buds are still tightly enclosed in new leaves. Due to this, a silky, downy quality in the leaves are retained. It usually seems quite tasteless at first and is the most delicate in terms of tea and flavor. The black teas have nearly twice the amount of caffeine from the white one.

 

THE PROCESS OF MAKING BLACK TEA

Black teas unlike the others are thoroughly graded after the final drying has been carried out. The reason is that during the rolling stage, a lot more sizes of black tea are graded, which therefore makes the sorting process to be a very necessary one. Without this being done, there would be a drastic change in the flavor of the tea from one cup to the other which usually is due to three factors: surface area exposed, size of the leaf and the extraction rate of flavor. Black tea is completely processed and its color after brewing ranges from between a dark brown color to a deep red color. The Black tea mechanically processed is generally, the one from the teabags. This is considered to be lower quality compared with black tea pressed manually.

 

THE PREPARATION PROCESS

Because it is completely oxidized, must be prepared in boiled water for highlighting the flavor. Generally, it should be kept in water between one and five minutes, but this depends by tea type.

 

THE CAFFEINE CONTENT

The complet oxidation process of the leaves increase the amount of caffeine in the black tea. After a good research seems that a cup (8 fl. Oz cup) can reach up to 70mg of caffeine but this depends by many factors, from the amount of leaf to the water temperature and duration of steeping. The average caffeine content for black tea is about 42mg (8 fl. Oz cup) considering many kinds of this tea. Because of high caffeine level, this became a good source of energy for the human body. Anyway, it must be consumed with moderation, no more than two or three cups a day.

 

CONCLUSION

In conclusion, black tea surpasses other teas but is weaker than coffee.
