[...] I'd say that you would probably get less caffeine if you actually ate the bean. Here's my theory:
If you grind up the bean and then brew it, you are exposing a great deal more surface area of the coffee and then passing water through it and extracting the caffeine pretty efficiently into your cup. Then you consume it as liquid which is quickly passed to your bloodstream
If you eat the bean, your teeth could never chew the bean up enough to even come close to the mechanically ground method (much less surface area). Also when you subsequently swallow the beans partially ground/broken big pieces etc., your body would not be able to break down, digest and process the bean fully enough to get enough caffeine into your blood stream like getting it from the liquid example above :wink:
......Science aside, I can drink two cups with breakfast, go and cup coffee all morning, drink two espressos and not get jittery. A handful of chocolate covered espresso beans makes me sweat and shake.
Does anyone know if these are ever enhanced for sure as mentioned above? [...] What makes them "espresso beans"? Unless they have added caffeine, there is no such thing as an espresso bean. You have to make them into liquid the proper way before you can call them espresso.
