Pressure-brewed coffee consists of forcing hot water, in a confined brewing chamber, through finely ground coffee under high pressure Pressure brewing requires super automatic coffee machines that grind whole beans, then feed them through a brewing cylinder (chamber). What does pressure do to coffee? The higher the pressure, the faster the coffee is extracted from … Read more

How do I increase … Read more
