Tea and Caffeine

Morning Peeps...

Its been a month since I blogged. Bad me. I’ve been focusing on new ventures that are coming up this fall. Like teaching a tea class at Open Kitchen and attending expos and events (more on that later). I have been loyal to my morning cup of Jade Oolong and Im about to cup a few more this afternoon. Yeah me!

I was sifting through some old emails and came across this interesting bit from my Peep over in England, Nigel Melican. He is an expert on many many tea related issues especially caffeine. So Id like to share with you what he said recently. A question was asked:

Q. “First, I was wondering which tea had the greatest caffeine content White,Green,or Black?…

A. “A 2007 study in Germany (Hilal & Engelhardt) looked at 30 Black teas, 2 sets of 30 Green teas & 30 White teas. This is the most comprehensive study I know. They found a range of caffeine:


Black tea 2.0 to 5.4% – average 3.5%

Green tea (1) 1.5 to 5.2% – average 3.4%

Green tea (2) 1.7 to 3.9% – average 2.9%

White tea 3.4 to 5.7% – average 4.9%


My conclusion from this is that to drink any particular color of tea for its low or high level is to fool yourself. Despite what many misguided (or unscrupulous) vendors may tell you, your black could be as low as 2.0% and your green as high as 5.2% – and even on average (if you could ever find an average tea) a black will be the same caffeine level as a green – from sample set 1 at least.


White tea scores higher on average than black or green, though a ‘high’ black or green could still beat a ‘low’ white.


Steeping practice will modify caffeine intake more than your choice of tea type. Halve the tea you use = 50% less caffeine in your cup. Treble steep your green or white teas and you will have significantly less caffeine per oz of water consumed than in a single steep of black.


Finally, don’t worry so much about caffeine in tea. Nature provided tea polyphenols to complex it – so you do not get the coffee jitters from tea – and the unique relaxing L-theanine to balance caffeine’s energizing effects. New research (in mice only, so far) points to caffeine having a protecting and reversing affect on Alzheimer dementia at a dose of 500mg per day – around 14 cups! That has to be an argument for increased tea drinking.


Analysis shows that the African cultivars are consistently high for caffeine content. Some can be up to 6% in parts of the year and the CTC manufactured types are the highest. Teas from Kenya and Rwanda are particularly good for combination of taste, high caffeine and high L-theanine (the stress busting amino acid unique to tea). In USA though it’s difficult to find these teas as straight origins. I suggest you seek out a supplier of Taylors Yorkshire Gold – their blend incorporates a lot of the best African teas – good and strong and my favorite for the morning wake up cuppa.

Q. “I know this has been addressed in the past, but once again….Which if any tea has the most caffine? I am a loose tea drinker, but also love my coffee. Coffee isnt agreeing with me anymore, but Ive gotta have that “buzz” in the morning to get me going. I have a job where I sit all day and look at a computer, and need to stay awake!…[I’d] appreciate anything you can advise me on.”

There you have it. Thanks Nigel!

Happy Sipping!

Tea and Caffeine

One thought on “Tea and Caffeine

  1. I wish there was better information available on the differences beyond just caffeine content in its delivery with the different teas. I’ve heard that green tea caffeine acts on its drinker differently, stimulating more quickly than a black tea does just as it’s absorbed into the hot water more quickly. This is probably true across the board as the real kind of difference between the teas. I look forward to more scientific studies about this aspect of caffeine in tea. –Spirituality of Tea
