type of caffeine teas

The right tea can activate you in a similar way to what coffee would. Theine found naturally in the leaves of the tea plant (Camellia sinensis), is the same substance as caffeine. Its name varies simply because it is talking about tea and not coffee.

However, the world of teas is vast and their properties, flavors, and amount of caffeine are different. Do you know which is the tea with the most caffeine? Join us to review our classification of teas and their caffeine content.

Caffeine And Tea

While the caffeine in tea and coffee are technically identical, the experience is different due to three key factors:

  1.  There is considerably less caffeine in an average cup of tea, especially when we consider green and white teas since these are infused for shorter times and at lower temperatures.
  2. L-theanine, an amino acid found only in tea, has a relaxing effect that counteracts the nervous effect of caffeine without reducing increased alertness.
  3. The high level of antioxidants found in tea slows the absorption of caffeine by our body, resulting in a slight increase of the compound in the system and a longer alert period without the fall at the end.

Teas with Caffeine

Identifying the tea with more caffeine is not easy, since the concentration of this element in each tea depends on factors as varied as the altitude where the tea leaves have been harvested, the oxidation time to which it was subjected and even, the time of the infusion. However, after processing data in several and in a general way, we present our ranking of teas by caffeine content.

The Black Tea

The black tea is topping the teas with caffeine list. The different references indicate that it has between 20 and 100 mg of caffeine for every 100 grams of product, depending on the variables indicated above. The Mayo Clinic, for example, maintains that a 237 ml cup of black tea contains between 25 and 48 mg of caffeine.

However, for example, Assam and Darjeeling teas have approximately 50-100mg of caffeine per cup, when prepared with 10g / 1L. For its part, Ceylon tea usually has between 50 and 90 mg per cup, of course depending on the infusion time and the variables mentioned above as well.

Matcha Tea

Since matcha tea is a variety of green tea, it could be inferred that it has less caffeine than black tea, however, this is not the case. The tea used for the Japanese tea ceremony is made by crushing whole leaves. Thus, when you drink a cup of matcha, you ingest the powder with which it is prepared and therefore, a greater amount of tea than when using tea bags.

A teaspoon of matcha tea is considered to provide 68 mg of caffeine, compared to 32 mg found in the same amount of green tea.

Oolong Tea

Oolong tea, also known as blue tea, is ranked number three. This generally has much less caffeine than black tea: between 10 and 60 mg of caffeine depending on whether it is a more or less oxidized oolong.

Green Tea

Green tea, famous for its potential slimming effects, has a content of caffeine that could be called medium, between 25 and 29 mg / 100 g. This is because, despite using young leaves for their preparation, they undergo a minimal oxidation process that generates a more moderate amount of caffeine than in those mentioned above.

White Tea

As it is a slightly oxidized tea, since it is collected and dried, it has less caffeine than the aforementioned varieties. Some researchers indicate that its content would be less than 1 mg.

Pu-erh Tea

Red tea can have more or less the same content of caffeine as white tea since it is also a slightly oxidized tea, although it is fermented to obtain its curious color and particular flavor.

Now that you know approximately the caffeine content of each variety of tea, you can choose the one that best suits your tastes and needs each day.
