During MatchaEasy workshop, we always hear question about caffeine. How much caffeine does green tea and black tea contain? Is drinking too much tea likely to affect sleep? Are there any side effects of consuming too much caffeine? Is cold brew tea lower in caffeine? We will answer them one by one⋯⋯
Caffeine Content
The caffeine effects of tea are milder than those of coffee
Because tea contains L-theanine, it gives people a feeling of relaxation. Therefore, although tea and coffee are both caffeine drinks, ingesting theanine while drinking tea can slow down the impact of caffeine on the body, resulting in a milder and longer refreshing effect.
Black tea has higher caffeine content than green tea
Based on the different tea making methods and tea types, black tea basically has a higher caffeine content than green tea. However, the caffeine content of matcha, which is also a kind of green tea, is also higher than that of ordinary green tea (tea leaf), because matcha is made from 100% original tea leaves ground into powder, which means that the tea leaves are almost directly taken into the stomach, so the intake of each content is all relatively high.

Caffeine content is difficult to generalize
Brewing the same tea, water temperature, brewing time, and even different tea sets will hot brew of green tea with cold-brewed black tea. The caffeine content of hot-brewed green tea may be higher than that of black tea. Therefore, we recommend that you observe your body’s reaction when drinking tea, adjust your tea drinking habits or brewing methods, and discover your relationship with tea!
