Abstract
A beverage brewing apparatus according to the present invention is provided with a brewing cylinder. A pressurizing piston is slidably fitted in the brewing cylinder. The pressurizing piston, in conjunction with a coffee filter tape, defines a brewing chamber inside the brewing cylinder. The pressurizing piston compresses coffee powder fed into the brewing chamber. When the powder is pressurized by the pressurizing piston in the brewing chamber, extremely hot pressurized hot water is poured into the brewing chamber by a hot-water supply mechanism. As a result, a coffee solution percolated in the brewing chamber runs out therefrom through the filter tape.
