Caffeine weight

Hi Jim,

I d "Caffeine is difficult to measure. Coffee tends to contain the most, followed by teas and soft drinks. But there are so many varieties, sizes and strengths of coffee that you can no longer make simple statements about how much is in your favorite cup of joe."

or

That's the article my wife read to me this morning. We have a division of labor on Sunday. I make the tea and breakfast and she reads me anything she finds interesting in the paper. I have to scrounge through the paper on Monday to learn the Saturday sports results. So

30mg/g of caffeine would almost equal the 200mg of tea over three cups of tea. That's almost 3% of caffeine by weight. I've drawn a blank on any caffeine number for tea.

The Upton website says this:

You can find this, and more, at their site

then click on "information", and 3/4 of the way down that page, on "caffeine and other health issues".

I know that you have often stated how URLs are trespassing here,and that you never follow them, but I offer you a link anyway since it contains a very specific answer to your question.

It ranges from 1.7% to 4.0% depending on tea variety.

Teasites that list caffeine content are the sames ones who claim their most expensive oolong makes hundreds of cups an oz. All you need for this group is a newserver and reader or if you have cheap MSN as an ISP Google Groups. If you want to know something about tea just ask the group and usually somebody can give you an answer without URLs. I did some homework and Nigel at Teacraft did a post back in 2000

which is more informative than websites simply repeating each other. You could Google all day and not find the kind of information on recent posts about TGY and LS. I'm the only one recently to ask a question about a Cantonese packaged puerh in a bamboo basket and not receive an answer. Too bad because it doesn't taste like a green or black but something I like better. I suspect it is a rare black LiuAn at $6/500g but won't know till an expensive black LiuAn arrives from China from a contact through my local tea shoppe. If they're the same I'll panhandle on Ebay all I can find in my Chinatown and finally retire.

Mike,

Jim's got a point in there somewhere. Nigel, if I recall correctly, emphasized that the data you get from one set of leaves does not necessarily carry over to others. Instead, he offers a set of guidelines that include such facts as the leaves closest to the tip of the stem -- the buds, for example -- contain more caffeine than the older leaves further away from the stem tip. I look askance at the Holy Mountain caffeine data.

HI Jim,

Tea has on average a caffeine contend of 2-4,average 3%(dry weight). Best Kalle

I think 3% is a good representative number if you throw out the highs and lows mentioned in posts and websites so that is 30milligram/gram.

Oh now I get it. The bamboo leaf that wraps the puer adds it own scent as the leaf dries out. I haven't done a core bore yet to see how far the scent permeates as I've been using leaf from the surface. Still the leaf infuses to a dark green unlike cooked and uncooked puers. There are still things you can discover about tea without reading about it first. I got a heads up when I read that puer packed in Pomelo is the same idea.

$6/500g

Just a minor point here: I doubt it's the leaf that's used in the basket; more likely split stems.

Note first of all that the caffeine level depends somewhat on how you make the tea; although the caffeine is very soluble and most of it comes out in the first minute of steeping, there's still a diifference with different steeping methods and times. So if a company actually took their teas and titrated them, then gave a caffeine specification in the catalogue, that specification may not actually relate to a cup you make.

Also note that some teas contain xanthines that are similar but not identical to caffeine. So, knowing a precise caffeine level may not translate to knowing the degree of biological effect because it's not just caffeine doing the job in all cases.

I'm not sure what you mean. The leaf is about 1 3/4 inches wide with the point and vein in the middle. Each leaf is probably 8 inches in length probably with a total of ten leaves completely wrapping the puerh. It'll be a while before I make it to the Botanical Gardens to double check.

Am I reading Nigels post wrong? It looks like he's saying that seedling tea has 1%-3% caffeine and clonal tea 3%-5%, then says most greens are from seedling and most blacks clonal so black tea has less caffeine.

Here is another site:

I would say the majority are 2.5-3.5%, or 50-70mg per 2g bag and 75-105g per 3g bag.

A 3g bag is labelled for two cups. Does that mean 12 or 16oz?

Interesting list. Why do people say that black tea has more caffeine than green. From the looks of this list that doesn't seem to be true.
