How much caffeine in trader Joe's decaf?

Answer 1

Decaf can contain anywhere from less than 1% to about 3% of the caffeine of caffeinated coffee. This is because it is easy to get most of the caffeine out, but very tedious to get just about all of it out. This amount of caffeine should not have an effect on people, however.

According to a study by the University of Florida, decaffeinated coffee contains some caffeine 8.6mg to 13.9mg / cup, versus about 85mg in a cup of non-decaffeinated coffee.

Two main process exist to extract caffeine from coffee. Before the treatment there is around 1 and 2.5% of caffeine in coffee, (some Ethiopian species contain almost none) and there is around 0.1% caffeine left after treatment. Based on these figures, a regular cup of coffee (home-made, not expresso) contains on average 75mg caffeine, while a cup of decaffeinated coffee contains on average 3mg.

In the United States federal regulations require that in order to label coffee as "decaffeinated" that coffee must have had its caffeine level reduced by no less than 97.5 percent.

Example: Panamanian coffee is about 1.36% caffeine by weight normally. This and many other arabica coffees are about 98.64% caffeine free even before anything is done to lower the caffeine content..

When 97% of the caffeine has been removed only .0408 % of the coffee weight is caffeine. About 4/100ths of 1%. At this level it is labeled "decaffeinated". How roasters label their products is another matter. Suppose two roasters roast Panama coffee that originally came from the same lot, and were decaffeinated together in the same vat. One roaster labels his decaf. "97.5% Caffeine Removed." The other says his is "99+% Caffeine Free." Which roaster is not telling the truth?

The answer is: They are both right. They are both essentially saying the same thing.

Answer 4

Decaf should range somewhere in the 2-4 milligrams of caffeine per cup range.

Answer 5

If you mean normal, not black coffee, you need to specify type and amount of milk and sugar because coffee is quite insignificant in calorie count compared to milk and sugar
