Despite being called a “stovetop espresso maker,” Moka pots don’t make authentic espresso. A Moka pot makes coffee that is stronger in taste than regular coffee but weaker than espresso. Moka pot coffee is 2-3 times as concentrated as regular coffee, while espresso machine coffee is 5-8 times as concentrated as regular coffee. Espresso has less caffeine than both regular and Moka pot coffee because the water goes through the grounds quickly with such high pressure. Both an 8 oz cup of coffee and a 2 oz shot of Moka coffee have 105 mg of caffeine. A 2 oz shot of espresso only has 93 mg of caffeine.
