USA Today had an article out yesterday about the caffeine content in decaffeinated coffees. The facts are quite interesting. We all kind of know that decaffeinated coffee does have some caffeine in it - just how much?

The University of Florida published an article in the Journal of Analytical Toxicology about decaffeinated coffee. The researches bought 10 cups of 16oz drip decaf coffee from 9 chain and local coffee houses and tested them on caffeine content.

Research found that Folgers Coffee Crystals was the only decaf with 0 caffeine. Others ranged from 8.6 milligrams to 13.9 milligrams (regular coffee has approx 170 milligrams).

Starbucks in particular was tested. Espresso decaf had 3-15.8 milligrams, while brewed had 12-13.4 milligrams. Interesting variance. Perhaps based on the cleanliness of the machines?

This research was conducted for health reasons, as many people cannot have caffeine due to some medical conditions. Caffeine as low as 10 milligrams can cause effects in sensitive people.
