Caffeine content of beans when eaten

[cyrilgoldenrock]

A friend told me that one coffee bean, when eaten, has roughly the same caffeine content as an espresso.
Obviously there are many factors affecting caffeine content of both beans and espresso, but roughly speaking, does anybody know?
Ive had a bit of a look on google but have only found average contents of brewed coffees, not beans.

Weigh a single roasted coffee bean. If its Arabica it typically contains anywhere between 1% and 1.5% depending on the origin and level of roast.

Espresso will contain anywhere from around 45mg to 100mg of caffeine.

Do the math and let us know.

Hi

Remember the old add "43 beans in every cup" ? Its actually pretty close.
I checked it once by simply counting the number of beans I used ended up grinding for one shot.

I conducted an experiment and posted it under 43 Beans

43 Beans weigh 7 grams or close to it

1 - 1.5% eh? Thanks for that. When i get home ill be on the case, weighing and calculating.
Was thinking of adding a few coffee beans to my trail mix for an extra boost when on the snow this weekend.

So did anyone do the math? :P

10g beans == between 60 & 70 beans == 100 - 150mg caffeine ==> say 2mg per bean.

So, answer to original assertion: balderdash. Are we surprised? :
