The common factors that alter the caffeine content in tea are the types of tea, the leaf grades, the brewing method, and the method of production.
What is caffeine?

Caffeine produces the chemical known as adrenaline, the hormone that is responsible for triggering the “fight” response in your brain. However, the overconsumption of caffeine might lead to the uncontrollable release of adrenaline which leads to anxiety disorders.
Increase in heart rate
Excessive intake of caffeine can create an altered rhythm in the heartbeat as it makes your heart beat faster. The level of impact is different for different people. So, if you are one of those who notice changes in the heartbeat rate after intake of caffeine, you should consider decreasing the amount of caffeine intake.
Complications in pregnancy
The excessive intake of caffeine during the time of pregnancy increases the risk for complications, the study shows. It can lead to the complications like low weight in infants and an increased risk of miscarriage. For this reason, it is suggested not to intake more than 300 mg of caffeine per day during the pregnancy period.
What affects the caffeine content in a cup of tea?
The tea leaf
It might be surprising for you to know that the same type of tea leaf provides different levels of caffeine when used in different ways. For example, you are more likely to have a high amount of caffeine in a tea when using the broken tea leaves rather than whole leaves for brewing. Likewise, the age of the leaves also impacts the amount of caffeine released in the tea. The new tea leaves are more likely to produce a high amount of caffeine as compared to the old leaves.
Time for brewing
The amount of caffeine released in the tea also depends on the time taken for brewing. When you place the tea leaves in hot liquid for a longer period of time, it releases more amount of caffeine.
The teas which are shade grown have higher levels of caffeine in them. When the tea is grown in a shaded area, there is a change in the formation of chlorophyll and other chemicals which results in releasing of a high amount of caffeine.
Type of water
Yes, it is true that the type of water used for preparing tea also has an impact on the caffeine level. However, the impact level is very low. The water that has high PH level reduces the infusion of caffeine which increases the level of caffeine release.

Caffeine does not cause real “addiction”
Yes, caffeine can cause mild physical dependence, but it does not create a real “addiction” as the other drugs do. Withdrawing from caffeine might cause some physical symptoms such as headache, fatigue, and anxiety, but it does not create any long-term harmful impacts like others. This is the reason it is not fair to refer the caffeine dependence as “addiction”.
