Caffeine weight
 

I just realized I have to guess at the amount of caffeine in a gram of
tea. If there is an answer I don't know it. I think it would be a
constant across the oxidation styles so the caffeine in a gram of
Silver Needle would be in the ballpark of puerh making the caffeine in
a cup a matter of brewing times and not leaf weight. This all started
when my wife read that coffee has 200mg of caffeine in three cups of
coffee which I assumed were 6oz each. I was drinking a mug of oolong
at the time and I could approximate the gram weight to make the the tea
but no clue to the caffeine level. My guess is 20mg of caffeine per
gram of tea. I derived that from the fact I would make a 6oz cup with
2 grams of tea for a total of 6 grams for the three cups or 120ml
caffeine which would be about half the given amount of coffee. What
numbers have you seen for caffeine weight versus tea weight?
