Caffeine is not damaged during the roasting of the coffee beans.

When hot water is added, the caffein separates from the coffee grounds.

After caffein was identified in 1820, its stimulating properties were discovered.

Caffein is also called guaranine when found in guarana, mateine when found in mate, and theine when found in tea.

Increasing the blood pressure is the best known property, it does this by inducing the central nervous system, the heart, the lungs and believe it or nor urine production.

The postponement of tiredness is another property, that is one of the many positive properties

It is also known to stimulate the strength of aspirin and to give slight relieve for asthmatic patients.

There have been suggestions made that caffein can lead to possible cancers and birth abnormalities.

These allegations have never been confirmed and as such there are no warnings from the US Food and Drug Administration (US FDA).

There quite a variation in the caffein contained in the different coffee beans. The average amount of caffein in a normal cup of joe is 90 to 150 mg.

When comparing the different types of coffee makers it was discovered

While the other coffee makers produced between 80 and 135 mg per cup of coffee. The drip coffee maker produced far more caffein per cup (115 to 175 mg).

Contrary to what is commonly believed, the cup of espresso contains as much caffein as a normal cup of coffee (100mg).

But if you compare the espresso with the same ammount in milliliter you find that espresso has far more caffein.

Caffein is absorbed much quicker by the body when taken as concentrated as in a cup of espresso.

The amount of caffein found in coffee blends will also vary.

The following are examples of the caffein content for different coffee blends:

• Brazilian Bourbons: contains 1.20%
• Columbia Excelso: contains 1.34%
• Columbia Supremo: contains 1.34%
• French Roast: contains 1.22%
• Costa Rican Tarrazu: contains 1.35%
• Vienna Roast: contains 1.27%
• Decafs: contains 0.02%

When you are sensitive to caffeine, you will turn to drinking decaf coffee.

That's how you can still enjoy a cup of joe without the ill effects of the caffeine.

The caffeine is removed before the coffee beans are roasted. This is done by treating the beans with chlorinated hydrocarbons.

After the treatment the solvents will be removed and the beans are roasted like untreated beans.

There are no known ill side effects to decaffeinated coffee, so you can drink as much as you want without feeling the effects of caffeine.
