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 moka pot is an Italian invention, first produced by Bialetti in the early 1930s. 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.
Drinking more coffee is linked to a lower risk of depression, according to a review of 26 studies published in Australian & New Zealand Journal of Psychiatry in 2016. For each cup of coffee consumed per day, the risk of depression decreased by 8 percent, the researchers found. However, it's worth noting that too much caffeine can cause problems in people who also suffer from anxiety, negating any beneficial effects the coffee can have on depression risk.
