How much real coffee is in instant coffee?

Java

An 8 oz. cup of brewed tea has 20-90 mg of caffeine. But we are talking about U.S. brands. When one refers to tea as a "brand", one is already in trouble. Those of us who really appreciate tea talk about the variety of tea leaves, where are they grown, the climate in which they are grown, how they are smoked, or cured, etc. We could actually sound more exotic and discriminating (and I mean it) than Javamanity.

Just try a one oz. cup of perfectly brewed Chinese green tea, and you would be forced to stay awake through the whole Republican or Democratic convention. I remember when I was in my tender youth and had to cram through a whole 2 weeks of grueling examinations. I drank Chinese tea every night and forgot the meaning of sleep. My hair stood straight up, without benefit of grease. After 2 weeks of this exhilaration, I stopped imbibing this heavenly elixir, and while I was walking from dinner table to bedroom, I fell straight like a plank and slept for two days straight.
