The Mystery of Decaffeinated Coffee by Gary Gresham

Caffeine has become America's most popular drug by far. 90% of Americans consume caffeine in one form or another every single day. Most of it comes from drinking coffee.

But if you're a coffee lover who prefers to avoid caffeine, you can still enjoy a cup of coffee that delivers rich flavor with decaffeinated coffee.

It's how the caffeine is extracted from coffee beans that is a mystery for most of us.

These are some of the methods currently used for decaffeinating.

Direct Contact Method

In the direct contact method the beans come directly in contact with decaffeinating agents, such as methylene chloride, after being softened by water or steam. Caffeine is removed by directly soaking the materials in the methylene chloride.

Indirect Contact Method

With the indirect contact method a water and coffee solution is used to draw off the caffeine. The solution containing the caffeine is then treated with a decaffeinating agent, such as ethyl acetate, and mixed back into the beans for reabsorption of the flavorings.

Sometimes this method is referred to as naturally decaffeinated because ethyl acetate is a chemical found naturally in many fruits.

Water Processing

This process is similar to the indirect method, except no chemicals are used. The coffee beans are soaked in hot water then the solution is passed through a carbon filter to remove the caffeine.

Swiss Water Process

In the Swiss Water Process method, the caffeine is still extracted with carbon filters but the beans soak in hot water that is saturated with coffee flavor. The result is caffeine removal without removing the coffee flavors.
