Good evening Alsinger and thank you for the interesting question.
Being a coffee drinker, I was suprised at how much caffiene I am
drinking, just by drinking one cup of coffee a day. I always thought
soda had more caffeine and tried to stay away from it as much as I
could - I guess we all learned something tonight!
According to sources listed below, the average cup of American-style
coffee contains about 100 to 150 milligrams of caffeine while the
average cup of decaf should range somewhere between 2 to 4 milligrams
of caffeine per cup.
Espresso: 100 mg
Tea: 40 - 60 mg
Jolt Cola: 58.8 mg
Mountain Dew: 55.0 mg
Plain Chocolate: 50 mg
Coca - Cola: 45.6 mg
Diet Cola: 45.6 mg
Dr. Pepper: 39.6 mg
Pepsi Cola: 37.2 mg
Diet Pepsi: 35.4 mg
Decaffeinated coffee: 2 - 4 mg
7 U: 0.0 mg

" According to Commercial Item Description (CID) A-A-20213B , the
United States Department of Agriculture mandates that decaffeinated
coffee cannot contain more than 0.10 percent on a dry basis in the
packaged item, as determined by Association of Analytical Communities
(AAOC) International Official Method 979.1 1. However, a reduction in
caffeine by 97.5% is the legally accepted method of calculation."

"Arabica coffee contains 0.8-1.4% caffeine. In other words, it is
naturally 98.6 to 99.2 percent caffeine free. That 1.1% average must
be further reduced by 97.5 percent to be considered decaffeinated."
