Black Tea Caffeine

 Black tea caffeine was first discovered in 1827. Called theine, the substance was known to have very similar effects as caffeine in coffee. Eventually, it was shown that theine of tea was actually identical to caffeine, and since then, the term has been dropped.

The relief from fatigue we find in drinking tea can be attributed to its caffeine content. Black tea caffeine is a stimulant that has been shown to increase speed in reaction time, increase alertness, and improve concentration. 

The physical effects include stimulation of digestive juice, the kidneys, and the metabolism in ways that possibly help eliminate toxins. An increase of mental alertness, shortening of reaction time, and improving efficiency of muscle action is brought about by caffeine’s stimulation of the heart and respiratory system, bringing more oxygen to the body.

A recent study on coffee shows that caffeine helps improve brain power performance and can be quite healthy, helping reduce the risk of heart disease and countless other diseases. However, because the study is still very new, the findings remain largely uncorroborated by other studies. Dieticians still warn against the bad effects of caffeine when consumed in large quantities. Because of its stimulating effects, caffeine can lead to heart palpitations, shortness of breath, and insomnia.

Black Tea Caffeine v. Coffee

Black tea caffeine has a distinct advantage over caffeine found in coffee. That’s because black tea caffeine content is lesser compared to caffeine in coffee. A cup of coffee yields as much as 16 mg of caffeine while the same cup contains only about a half or a third of black tea caffeine. This reduces the danger of imbibing too much caffeine in your system since drinking even several cups of tea does not have quite the same potent effects as a cup of strong black coffee. 

Yet, it should be noted that black tea caffeine can be quite confusing. One of its more confusing aspects is the fact that coffee actually contains less caffeine than tea when measured in its dry form. But when prepared in a cup, the caffeine content of coffee is significantly higher than the black tea caffeine content in a cup.

What Determines Black Tea Caffeine Levels?

The reason purportedly has something to do with how the tea was processed. But there actually several factors involved that may help determine black tea caffeine levels. These include the variety of tea leaf, where it is grown, particle size used, the particular tea leaf cut, and the method and length of brewing or steeping. 

Also, studies show that black tea caffeine levels are determined by the leaf location on the tea plant. The lower the tea leaves are located, the more caffeine they contain. That’s because the leaves near the bottom of the tea plant are more mature and, therefore, have more of the phytochemicals and substances that naturally occur in the plant. 

Black tea caffeine, especially, is higher compared to all other tea caffeines. This probably has something to do with the way black tea is processed. Black tea undergoes full oxidation, which accounts for its strong taste.
