Coffee & Caffeine

[eupraxia]

I would like to know, is there more caffeine in freeze dried, jar coffee than the is in fresh ground coffee.

Is there any more in coffee than if when you grind your own beans.

Or is there the same amount in all of them.

see gingerflaps posting above. the quick answer is that a cup of instant coffee has less caffeine than a cup of percolated coffee which in turn has less than a cup of 'dripped' coffee. don't know about the beans!
