Tea and Caffeine Content

Tea is one of the healthiest and delicious beverages you can have on a daily basis. There are so many different types of teas available and they have varying ranges of caffeine in them. While in your average cup of coffee you will get about 110mg of caffeine, giving you a good boost. The average caffeine amount in tea can be affected by steeping time, blends, and of course the kind of tea you are drinking.

The Strongest Teas

The standard amount of caffeine in an 8oz cup of tea is around 80mg.  There is a huge myth surrounding tea and caffeine, and the amounts different colors produce.  Often it is believe that Black teas have the highest levels while white teas are the lowest.  This is largely false, as the strength in tea has largely to do with brewing, kind of leaves or buds, and how it was grown.  However, these are teas from highest to lowest based on the amount of caffeine:

How Leaves and Buds affect Caffeine

Caffeine content has largely to do with how your tea is grown, and packaged.  Tea that is grown in the shade produces a lot more caffeine than the sun grown plants.  that has been finely chopped, sliced, or ground into a powder will have a much larger caffeine output than leaves.  This is because more caffeine is able to escape from the leaf when it is cut.  Newly grown leaves and buds are often used to make white tea, and these contain more caffeine than when older mature leaves.

Are There any Decaf Teas

There is no such thing as naturally decaffeinated tea.  Only herbal tea caffeine content is naturally zero, to very minimal.  These herbs can come mixed in with black, white, or green teas making the caffeine amount lower.

How Brewing Affects Caffeine

Everyone has a favorite way to brew their teas, whether it is for iced tea or a soothing cup before bed.  When you brew tea and caffeine needs to be lower than normal, you will need to steep it for less time.  This means you do not want to let your tea bags, or leaves soak in the hot water for an extended period of time.  However if you want a tea caffeine content that is high, then you will want to leave it in the water steeping for longer than the recommended time.

Specific Teas and Caffeine

There is a general rule of caffeine in teas you can count on if you brew them for the standard times.

    Assam Black Tea (FTGFOP Grade) – 86 mg
    Bai Mu Dan China White Tea – 75 mg
    Chinese Ti Kuan Yin Oolong Tea – 37 mg
    Indian Green Tea – 59 mg
    Kenyan Green Tea – 58 mg
    Ceylon Black(OP Grade) – 58 mg
    Jasmine Tea – 5-20mg
    Pu-erh – 37mg

  • I was wondering why some teas have caffeine and some don’t ? also is it better to drink teas without caffeine or very little caffeine ?

    • TeaVivre

      Thanks for your question.

      Firstly, we must admit that tea grows with the content of caffeine. There is no such thing as naturally decaffeinated tea. Only herbal tea caffeine content is naturally zero, to very minimal. These herbs can come mixed in with black, white, or green teas making the caffeine amount lower.

      Generally, it will not effect our health if you are not so sensetive to it. And there are two main variables that influence the caffeine content of a cup of brewed tea: the type of leaf and the tea preparation method. On average, the young bud and first leaf generally have slightly more caffeine than leaves picked from the lower part of the tea bush.

      Besides, many parts will affect caffeine content such as the amount of leaf, the leaf particle size, water temperature and steeping time. For example, tea steeped in hot water for a longer time will release more of its caffeine than tea steeped with cooler water for a shorter period.

      Moreover, the caffeine in tea also bebefit to our body if we take suitable amount of it. Here is an articel which may provide more details. https://www.teavivre.com/info/caffeine-in-tea/. SO, we can’t tell if it better to drink tea with little caffeine or without caffeine.

      Hope it is helpful for you!

  • I read of a tea that has much more caffeine than coffee, is there such a tea, if so what is it and where does it come from

    • TeaVivre

      Thank you for your question.
      Fresh tea leaves content of 2% -5% caffeine
      The more south of the planting area, the higher caffeine, the big leaf species was higher than the middle and small leaf species.
      The second pick leaf contain of the highest caffeine, the summer tea have the highest caffeine.
      Production process also has an impact on the caffeine content. I don’t have extra answer about which tea contain higher caffeine than cafe.
      Almost all the tea, one cup tea contain caffeine far less than coffee. Due to we just drink the caffeine separate out from tea leaves, but we usually drink all the coffee which we brew in the cup.
      Hope it helps.

  • Hi.
    I am an epileptic; however I drink sleepy time teas; (some from a homepathic specialist so there are more herbs than YOGI) and detox teas….will these affect my medicine?

    • TeaVivre

      Thanks for your question.
      Usually it don’t produce harmful substances if we don’t drink normal teas(green tea, black tea, pu-erh tea, oolong and white tea) in 2 hours before or after we take pills.
      But we must inform you that the tea have drug resistance and the herbs is a little special, Many herbs were used as traditional Chinese medicine.
      It would be better to consult the professional advice from the doctors.
      Hope it helps

  • I have prostate cancer and after months of medication I start radio therapy tomorrow for the following eight weeks. Advised to reduce caffeine intake…….what sort of tea can I drink….if any.

    • TeaVivre

      Dear Philip,

      Thank you very much for writing to us.

      Sincerely sorry to hear that you have prostate cancer. Tea contains not only caffeine, but also Tea Polyphenols, theophylline and catechinic acid and so on. These ingredients are good for our body, but these will affect medicine intake. So I think you’d better do not drink any teas. Hope this is helpful for your concern.

      Wish you will recover soon and will be happy every day.

      Wish you will recover soon. And also wish you happy forever.

  • kim

    hi, I like drinking Jasmine and Pu-er teas. However I am concerned is whether consuming these teas will obstruct my body from absorbing calcium?

    • TeaVivre

      Hi Kim, it is rational if you are concerned about the calcium. This is also one of the reasons why we always ask people to drink tea properly, especialy not to drink too much or too strong teas, because if you drink too much, the amount tannic acid migh exceed the capacity your body can deal with. So it is important to stay in the proper amount, about 3 to 5 cups eveyday.

  • I am suffering from irregular heat beats. I am supposed to stay away from caffeine. I also understand that tea can improve helath and good for health. What is the best tea i can take. Is it recommended that i take tea with milk?

    • TeaVivre

      Hello Sundar, I’m sorry to hear about that. For your concerns of the tea’s caffeine, basically all kinds of tea contain caffeine, because tea tree is a kind of plant contains caffeine. But you can find some de-caffeine tea in the market. However, before you drink any tea in, it is suggested to ask your doctor for more professional advice about how much tea you can take.
