The word ‘espresso’ may spring to mind when we talk about pressure brewed coffee, however, there’s more ways to brew with pressure than the stock standard espresso machine. Pressure brewed coffee merely describes a cup of coffee that is extracted using…you guessed it…pressure, resulting in fast extraction times and a more intense brew (when compared with other brewing styles).
Anyone who knows anything about coffee knows what an espresso machine is – they’ve been keeping us caffeinated since 1901.
Let’s take a quick look at the three most common ways to brew coffee with a little pressure: The espresso machine, the Moka pot, and the AeroPress brewer. Today they come in various shapes and sizes, with loads of features and gimmicks. Don’t get confused by flash machines though because the basics are the same: pressurized water is pushed through a chamber/puck of finely ground coffee beans, through a filter, resulting in what we call a shot of espresso.
