Dear Wired:
For most coffee beans, it begins with a nice, long soak!. This submersion draws the caffeine from its beans, leaving us with a bushel of decaffeinated java seeds ready to be roasted, brewed, and slurped down!.
But hold that cup of joe!. This tastes like sludge!

The caffeine isn't the only thing lured from the beans during their decaffeinating bath!. The coffee's flavor also seizes that moment to beat a hasty escape!. So brewers need to coax the coffee's good taste back!. We'll lay out the three primary methods of maintaining taste while separating a bean from its caffeine!.!.!.

In one practice, the beans' post-soak water is mixed with a solvent that separates the caffeine from the liquid!. Alternatively, the caffeinated water can be forced through activated charcoal or carbon filters, which also separates the caffeine from the solution!. After either method, the coffee beans are re-submerged in the now-totally-caffeine-free watery extract where (hopefully) they reabsorb their flavor!.

Another method that immerses the beans in one heck of a strong steam bath, and then dunks them in carbon dioxide!. The CO2 scares the caffeine away, but keeps the beans' taste intact!.

So, how successful are these processes!? To be called "decaffeinated," caffeine levels must remain below 2!.5 percent!. And that dictate has the long arm of the law behind it!. So bring on the big mug of soy-mocha-latte-ccino -- and make it a decaf!.


most of the caffiene is either chemically removed (you dont want to drink that coffee) or by a process known as the swiss water method!. lately I have heard about a coffee bean that is supposedly genetically created to be caffeine free!.Www@FoodAQ@Com

it's usually a chemical process but there are companies that use water to remove the caffeine like Lavazza: http://www!.all-things-italian!.com/prodde!.!.!.Www@FoodAQ@Com

Used to work for Kenko, the smell of the decaf plant is awful, like tom cats pee, doesn't smell nice at all, if it smells that bad it can't be good for youWww@FoodAQ@Com

A number of different methods but the chemical method (also called the traditional method) is most common!.Www@FoodAQ@Com
