Of course, if you simply want to cut down on your caffeine intake, rather than eliminating caffeine from your diet completely, there are alternatives other than decaffeinated coffees.
One is to drink less coffee while focusing on enjoying it more. This is a good tactic for people who consume too much coffee at work out of habit or reflex. Rather than drinking the coffee from the automatic coffee maker or urn, for example, make your own coffee carefully in a small plunger pot, focusing your attention on the act of brewing and drinking.
You can also buy coffees that are naturally low in caffeine. Specialty coffees contain considerably less caffeine than cheaper commercial coffees. Most inexpensive commercial blends are based on robusta coffees, which contain almost double the amount of caffeine as arabica. So if you drink a specialty coffee, you are probably consuming considerably less caffeine per cup than if you were drinking a cheap canned coffee.
Lastly, you can amuse yourself making low-caffeine blends by combining decaffeinated coffees with varying amounts of distinctive, full-bodied untreated coffees. Kenyas, Yemens, the best Ethiopias, and Guatemalas, for example, all pack enough flavor and body to spruce up even the drabbest of decaffeinated beans.
