Abstract

A beverage brewing apparatus and method using microwave energy is disclosed. The apparatus comprises a pressurizable water reservoir and a filter chamber disposed below the reservoir. The reservoir is provided with pressure overflow means which, in operation, prevents water in the reservoir from overflowing into the filter chamber until vapor pressure is built up in the reservoir due to the influx of microwave energy so as to force the heated water to overflow into the filter chamber to mix with an infusible material, e.g. ground coffee to make a beverage.
