Tea Article: Discussing caffeine levels in tea

A common claim is that black tea caffeine content is much higher than that of green or white tea. Many people will always make a choice to drink green tea believing that the caffeine content is much lower. There are also people who say that green tea has zero caffeine…

In the following article we clarify these false claims and discuss what actually affects the caffeine content in different types of tea. Feel free to check it out!

That’s a good article, very interesting. I was aware that the buds of the tea naturally contain more caffeine than the leaves, but nitrogen effecting caffeine levels is new info for me.

Also, I read somewhere that decaffeinated teas do contain caffeine even after the decaffeinating process… it’s just a very very small amount. You might want to check that :)

Thank you!
And yes, you’re right. They do contain a very small amount of caffeine, that it’s probably not even worth mentioning it. I’ll consider editing that part :)

People also mistakenly believe white tea has little to no caffeine. If its picked from the buds and first leaves, it will definitely have a good dose of caffeine. Also spring picked tea has less caffeine than summer picked tea.

Mei Leaf did a really informative video about caffeine in tea: https://www.youtube.com/watch?v=d7jQ1uFoJXY

Thank you for sharing! I’ll check it out.
And yes, you’re right about that!

I always go by how much tea I can drink in a day and I can drink more green teas than I can any other tea without feeling a caffeine rush.

I agree that there are also some variables based on the person themself. Green tea usually doesn’t affect me at all, neither do Chinese black teas. Indian black teas however have as big an effect on me as coffee.
Always best to make your own judgement on how you feel at the end of the day! :)

I’ve always wondered if it had to do with the L-theanine but it appears black has more than green. It might have to do with brew times and how much tea leaf is used. I find most people brew their Pu-erh way too strong for me. I go half the leaf amount.

Matcha is one green I can’t even drink at all because it’s too high in caffeine. The caffeine level has to be close to or more than coffee. Most times I am drinking Chinese greens or light oolongs with the occasional sencha (which I count as two teas because it does have a bit more caffeine punch).

i almost love tea and always everyday drinking tea, this article give me some education more and more about tea..anyway nice article good job
