For those who would be inclined to freeze your coffee, bear in mind that by freezing your coffee beans, you remove 15% of the caffeine. Maybe that doesn't seem like much, but keep a few details in mind.

* The average cup of joe contains 100 mg of caffeine; this removes 15mg.

* If you drink drain cleaner strength coffee such as that served at Starbuck's, you're getting about 500 mg of caffeine per cup. That knocks out just around 75 mg of caffeine from your prized blood transfusion.

The moral of the story then is simple. If you like caffeine, don't freeze your beans.
