Coffee gives jitters. Espresso doesn't seem to?!
Answers: Was wondering if anyone could explain why one cup of coffee can make me a bit jittery but if I have a 20 oz latte with two shots of espresso it just makes me feel alert? Can't figure this one out. Anybody get this effect or know why someone would?
Espresso can be made from several different roasts and several different varieties, but the main reason is that espresso extracts less caffeine during the brewing process.
True, roasting coffee to a darker level burns off caffeine, but again, the brewing process is the key to the reduction.
quality of coffee different amounts of caffeine removed from grains when prepared.
wet25 is totally right.
Espresso beans are usually dark roast that has less caffeine.
