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.
