Caffeine and Coffee

Caffeine is a natural substance that is present in the leaves, seeds and fruits of more than sixty plant species worldwide.  Many food and beverage products made with these ingredients inherently contain caffeine.  In addition, caffeine is sometimes added to foods and beverages during the manufacturing process in order to enhance flavor, or in the case of medications, to enhance efficacy.

Factors that Affect the Caffeine Level in Coffee

Each of the following can slightly alter the level of caffeine in decaffeinated coffee so that it is above or below the typical caffeine level.

1.  Blend composition

2.  Brewing extraction rates

3.  Grind

4.  Roast color

5.  Water temperature

Higher extraction rates, warmer water, a finer grind, and a lighter roast all result in a higher caffeine level in decaf coffee.
