Green tea powder known as matcha is primarily created in Japan from stone-ground tea leaves. There are several reasons why matcha has a lot of caffeine.

First of all, unlike a cup of tea that has been properly prepared, when you consume a bowl of matcha you are actually swallowing entire tea leaves. This implies that many of the health-promoting substances found in tea, such as caffeine, l-theanine, and antioxidants, are being consumed in concentrated form.

Prior to harvest, the matcha tea plants are shaded for a few weeks, which also raises the caffeine level.

Black tea

Caffeine content in one cup of yerba mate can reach 180 mg, while Guayusa can have even more. This has a lot to do with preparation, as the drink is usually made with a leaf to water ratio that is extraordinarily high.

A gourd is first filled with leaves about two-thirds of the way, and then hot water is added. The beverage can then be savored using a bombilla or metal straw that automatically filters out the leaves.

Shaded green teas

Shaded green teas

Prior to harvest, certain specialty tea trees in Japan are shaded for a few weeks, which raises the amount of caffeine in the resulting tea. Kabusecha plants are normally shaded for around two weeks before harvest, compared to three weeks for Gyokuro and matcha plants.

Caffeine and tea

The amount of caffeine in tea varies based on a number of factors, including the characteristics of the tea itself and various brewing and preparation techniques. These consist of:

  • Tea varietal
  • Harvest time 
  • Growing practices
  • Processing methods
  • Steep time
  • Water temperature
  • Amount of tea leaves

It might be challenging to calculate the precise caffeine content of any specific tea since the amount of caffeine varies on so many distinct factors. As a rule, dark teas, pu-erh teas, and matcha have a high caffeine content, whereas white tea, matcha, and oolong tea have a lower caffeine content.


Contrary to other caffeinated beverages like coffee or energy drinks, camellia Sinensis tea includes both caffeine and a special substance called l-theanine. L-theanine serves to relieve tension and promote calm and relaxation whereas caffeine is a stimulant.

Many individuals claim that coffee and l-theanine work together to produce a meditative state that is great for concentration and attention. Although all genuine tea includes both l-theanine and caffeine, matcha and shade-grown green teas like Gyokuro and Kabusecha tend to be exceptionally rich in l-theanine. 

With this combination, you could experience caffeine’s effects a little bit differently, feeling calmer and more invigorated rather than as nervy and jittery.
