How Much Caffeine Is Present In Tea
The caffeine content of tea varies widely from tea to tea, and depends on the way it is made.
But tends to be within the range of 15-70mg per 8-ounce cup.
Caffeine can also be measured in terms of milligrams of caffeine per gram of dry tea.
A teaspoon of dried tea leaves usually weighs around 2.5 grams.
The amount usually used to make a single cup, although this varies depending on the type of tea.
A study of the content found that the caffeine content of tea ranged from about 3 mg/g to 30 mg/g.
Which would result in a cup of tea containing between 7.5 mg and 75 mg of caffeine.
Caffeine Content Of Specific Teas
Now that weve covered some general rules around tea and caffeine content, we can dive more into each variety of tea and how they differ, as well as what makes each unique.
First, you need to know that three parts of the tea plant are used to make tea.
The tea bud is the youngest and most caffeinated part of the plant. From the bud, a young tea leaf develops. It is bright and fresh, and contains a good amount of caffeine, but less than the bud. The mature tea leaf has the lowest amount of caffeine.
Does Green Tea Contain More Caffeine Than Coffee
Coffee and tea are often compared, and for fair reason. Both have centuries of heritage, are enjoyed across the world, come from plants, can be enjoyed hot or cold.
Generally, its accepted that coffee contains much more caffeine than tea. A quick Google search shows that in 100ml of coffee, theres 40mg of caffeine, whereas for the same volume of tea, theres only 11mg.
But one type of tea stands out among the rest as far as caffeine is concerned: green tea. Depending on how long theyre steeped for and where they come from, green tea leaves can actually contain much more caffeine than other types of tea.
To learn more about how this compares to coffee, I spoke to two experts. Read on to find out what they said.

How Can You Reduce Caffeine In Green Tea
If you are still worried about caffeine in green tea and want to reduce caffeine consumption, here are few techniques you can follow:
Why Do Different Kinds Or Types Of Tea Produce Different Amounts Of Caffeine Content
Many white teas from outside of Fujian, China have more caffeine than black teas simply because they are prepared with more tips or buds. Similarly, caffeine levels in tippy black teas and green teas will be higher than in their leafy counterparts. Tea stems, on the other hand, contain extremely little caffeine. Even though they look like needles, they are actually petioles, which are thin segments of a leaf connected by a stalk. They are usually discarded when preparing tea, so most people would assume that they would not affect the caffeine level in the final product.
The amount of caffeine in tea is determined by how much of the dry leaves are used when making it. If you were to use all of the dried leaves, then the result would be very strong and probably cause problems for some people. Most of the time, however, only a part of the leaves is plucked from the plant during harvesting, so the resulting tea is not as strong. For example, if you were to pick a cup of coffee, it would be almost pure caffeine. However, if you were to pick two cups of coffee, then it would be mostly caffeine with some other ingredients contributing additional flavor notes such as beans or milk. In tea, there are many different varieties and grades of tea plants, but most of them fall into one of three categories: first flush, second flush, and old crop. First flush tea is made from young, tender leaves that are just beginning to develop color and taste.

Measuring Caffeine Levels In Tea
There are many ways that caffeine is measured, depending on when in the lifecycle of a cup of tea you calculate it.
As a result, its hard to make an absolute determination on which tea has the highest and lowest amount of caffeine. All the factors mentioned above play a role in the chemical makeup of the tea youre drinking.
Any tea manufacturer can choose to take one aspect and declare X-amount of caffeine in this tea bag or this loose-leaf tea. But where theyre taking their data from is essential.
They could be measuring the caffeine content at an ideal moment in time when it is exactly what they want, but it could change later down the line due to processing.
Quantity is a significant factor, too. Obviously, the more you drink, the more caffeine you will be getting.
And keep in mind that tea isnt just caffeine. It also contains many other ingredients that are often much more beneficial, like EGCG and L-theanine. Some of these ingredients can also increase awareness and concentration without giving you the trademark caffeine buzz.
Caffeine In Japanese Green Tea
Japanese green teas are popular for their rich flavors and aromatic brews, providing a unique experience in each cup. Each type of tea ranges in caffeine content, depending on how the tea leaves are processed after being harvested. In comparison to other green teas, Japanese green teas often have higher caffeine content due to the gentle steaming process.
However, the effects of caffeine from green tea are different from those in coffee as caffeine from tea is metabolized differently by the body. While caffeine in coffee gives you a quick, short jolt of energy, the caffeine in tea is bound to antioxidants which slows absorption by the body. In return, you receive a steady and even supply of caffeine for a longer period of time. This allows the body and mind to enjoy long-lasting, health alertness without the jitteriness often experienced from coffee.
There are also Japanese green teas and herbal teas known to have low or no caffeine. Read below for our recommendations on the best tea for you, based on your personal caffeine needs and preferences.

A Brief History Of Tea
Shennong was preparing to sip from his bowl of freshly boiled water, but as it was cooling, a gust of wind blew leaves from a nearby tree into it.
The Yunnan Province in southwestern China is said to be the birthplace of tea. The oldest cultivated tea tree in the world, estimated to be around 3,200 years old, can be found there in the city of Lincang.
There are many legends surrounding the discovery of tea in China, but one of the most popular attributes it to the legendary Emperor Shennong, who lived about 4,500 years ago. As the story goes, at the time there was a decree that all water must be boiled before drinking. Shennong was preparing to sip from his bowl of freshly boiled water, but as it was cooling, a gust of wind blew leaves from a nearby tree into it. The leaves changed the color of the water and imparted it with a light and pleasant flavor. The Emperor immediately felt its restorative power, and shared his discovery with his subjects.
While the Emperors story is compelling, its probably a myth. Historians believe tea drinking comes from ancient, pre-Dynastic traditions in southwestern China. Whatever its roots are, theres no denying teas importance in Chinese culture and its global impact.
What Causes Caffeine Levels In Green Tea To Change
While 30-50mg is an estimation of how much caffeine is found in most eight-ounce cups of green tea, this amount may change depending on how its steeped.
Heres a look at what alters caffeine levels in green tea:
- The amount of time the tea has been steeped. How long to steep green tea depends on the caffeine content you prefer. The longer it steeps, the higher the caffeine content will be.
- The ratio of green tea leaves to water. Tea bags come pre-packaged with a fixed amount of leaves per bag. Doubling up on tea bags will, of course, double the amount of caffeine. Loose-leaf tea, on the other hand, may be steeped in varying quantities which will cause caffeine levels to go up or down depending on how much is used.
- The temperature of the water used to steep the tea. The hotter the water, the faster the caffeine will be released into the tea.

Does Green Tea Have Caffeine
Yes, green tea does contain caffeine. In fact, almost all teas contain caffeine. This is because things like black, green, or white tea all originate from the same plant: the Camellia sinensis. Its only which part of the plant that the leaf is picked from, and how its processed afterwards, that dictates what kind of tea results and the final caffeine content. In other words, unless you get it decaffeinated, green tea and any other type of tea is going to have caffeine.

Green Tea Vs Black Tea
Black, green, white, yellow, puerh and oolong teas are all from the same plant: Camellia sinensis. The difference in the taste and tea type comes down to how the leaves are processed after being picked. In the case of green, oolong and black tea, this is all about oxidation in other words, the extent to which the enzymes in the leaves react with the oxygen in the air, controlled by steaming, firing or rolling the tea leaves.
Does oxidation affect the amount of caffeine? Well no, not strictly. One of the biggest misconceptions about tea is that green tea contains less caffeine than black tea, and that white tea is the least caffeinated option of all.
Why Tea Has A Better Caffeine Content Than Coffee
Coffee, with 96 mg of caffeine per cup, does contain more caffeine than tea. However, don’t forget that high caffeine teas like Zest Tea can easily trump that. High caffeine tea is better than coffee for a few more reasons:
Quick and convenient to brew, especially if you pick pyramid tea bags.
Better value for money – you can re-steep tea leaves multiple times, while coffee beans are only brewed once.
Not everyone likes the flavor of coffee, but if you do, then black tea will appeal to you most. It’s rich, bold flavor goes great with a splash of milk. You could even try turning our classic Earl Grey high energy tea into a latte, called a London Fog.

How To Reduce Caffeine In Green Tea
You love to drink green tea, but you feel discouraged by the caffeine content. Not to worry, there are ways of decaffeinating it so that you never have to suffer the side effects anymore.
Just follow these simple steps.
- Soak it in water for about 30 seconds before boiling: The fact is that the longer you soak, the more the teas essence diffuses. So, do not soak it longer so that youll still have much to get from it.
- Select the variety with less caffeine content: Among the various types and brands of green tea, Matcha has the most caffeine, while Hojicha has the minimum. So, while going to the stores to get some green tea, do well to check the labels.
- Drink hot: Taking your tea hot will let you get the most of L-theanine, which works hand-in-hand with caffeine in green tea. It is an amino acid that works to counterbalance the effect of caffeine. The result is that you enjoy the benefits of caffeine and ditch its downside.
- Drink some water: Should you feel you are suffering from caffeine overdose at any time, drinking lots of water is one way to flush it out. You only wont mind that you have to pee frequently.
Moreover, some factors usually affect the caffeine content in green tea. Some of these factors are the geographical location of cultivation, time of the season leaves were harvested, culturing, and processing method.
So, you shouldnt be taken aback if the caffeine content in your green tea is moderate or above normal.

Which Teas Have No Caffeine
If youre drinking tea for the caffeine, youll want to avoid any popular herbal teas such as ginger tea, lemon, or hibiscus tea. This is because most teas that arent from the plant Camellia sinensis dont contain any caffeine at all.
Black, green, oolong, and white tea can all be through processing with chemical solvents or carbon dioxide. However, even after decaffeination, these teas will still contain a small amount of caffeine.

Assamica Vs Sinensis Leaves
Another difference between tea types in terms of caffeine is the exact tea plant used.
The most common tea plant used is the Camellia sinensis plant. This is the Chinese version, and is the one thats been first used, as tea was developed as a common drink.
Its also what the British brought back from China, and what we all know as tea.
Camellia Assamica is a close cousin of this plant, and it was given its name by the region in India where it grows. It gained popularity after the British offered real estate to anyone who wanted to grow tea, in India, to destabilize Chinas monopoly on tea.
As such, the two plants became fairly balanced in terms of how well known and used they were.
Assam teas have more caffeine than Sinensis versions, though exactly how much more is not clear.
Youll usually find Assam tea leaves in teas grown in India, Sri Lanka , and some parts of Africa.
Many breakfast teas a blend of black teas also use Assam in their blend. Some are entirely Assamica teas, and this gives them a stronger, bolder, nuttier flavor than Sinensis black teas.
