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 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:

  • Black Teas
  • White Teas
  • Green Teas
  • Herbal and Regular Blends
  • Herbal Teas (No 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

Not only is tea delicious but it is good for you, and can improve your health.  It doesn’t matter which one you prefer drinking, all are tasty.  Above all else, you want to make sure you have excellent quality tea.

    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 response:


    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 response:


    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.

  • TeaVivre response:


    Hello Tracey, normally white tea contains a small amount of caffeine. But we are not certain about the tea of a specific brand. It is suggested to check with the company for a more precise result.
