Coffee and Caffeine FAQ

Let me state for the record I am not 100% sure on this but I
believe that moka should be similar to a strong cup of coffee. Not
the same as the thin swill you will get a the diner but similar to a
good strong cup of coffee. To stay under 300 mg I'd
stick to one mug a day.

Don't forget that other foods and drinks have caffeine so
coffee is not your only intake. So you might even want to step back
to a single cup instead of a mug.

This all assumes you are making a proper cut of coffee. If
you are using a two tablespoons of coffee for a whole pot (the
approximate amount used in my office) then the dishwater you get will
have less caffeine (and flavor).
