Moka coffee is coffee brewed with a moka pot, a stovetop coffee maker which produces coffee by passing hot water pressurized by steam through ground coffee at a lower pressure than an espresso maker. The flavor of moka pot coffee depends greatly on bean variety, roast level, fineness of grind, and the level of heat used. Due to the higher-than-atmospheric pressure involved, the mixture of water and steam reaches temperatures well above 100 °C, causing a more efficient extraction of caffeine and flavors from the grounds, and resulting in a stronger brew than that obtained by drip brewing.
