Great question. While I think degree of roast may change/adjust/do something to the caffeine content, the original bean also must be looked at...
I have friends look at me in a very strange way when I say I have 2 or more double espresso's in the morning.
I may be wrong here and get tons-o-opinions but it is my understanding that espresso actually has less caffeine then say a regular cup of coffee (espresso being a process.)
Most people think that espresso is a dark, horrid, loaded to the eyeballs tiny cup of something that has way, way to much caffeine. NOT.
Mountain Dew has more then anything on the market...
Richard, guess I had better go do a bit more research...
will get back to to you,
That said, how do we measure caffeine content.
