There is a nice FAQ on tea at http://www.enteract.com/~robchr/tea/faq.html. The section on caffeine content follows: The amount of caffeine in a cup of tea varies tremendously, depending on the variety of tea and the brewing time. There is a great deal of contention about the caffeine content of various kinds of tea. Most people firmly hold the opinion that green tea has less caffeine than black, but a professional tea chemist has informed me that this is not true. Contrary to popular belief, green tea is likely to have just as much caffeine as black; and there is no reliable way of knowing in advance just how much caffeine is in your cup. I can report that the most caffeinated tea I have ever had was green. In 1995, I ordered a small pot of Yin Hao jasmine at a local coffeehouse, unaware that this delightful, high-quality delicacy was eye-popping, jaw-clenching rocket fuel. After two small cups, my hands were trembling and I could barely sit still. In fact, that same afternoon, I sat down and wrote this entire document in twenty-five minutes. [The last sentence is a joke. But everything else in the preceding paragraph is absolutely true.] The only way to know for sure how much caffeine you are drinking is to have each individual cup tested in a laboratory, which is not terribly practical if you intend to drink it. My advice is to pay attention to the tea you drink and judge it by how it makes you feel. There may be no better way to decide how to regulate your intake. -- Brian Glass | [log in to unmask] | http://www.lni.net/bjg | 734-995-9022 ----------------------------------------------------------------- Like one who takes a dog by the ears Is he who passes by and meddles with strife not belonging to him. - Proverbs 26:17
