摘要： Provided is a coffee brewing apparatus (100) having tubing (108) that extends from a one-way valve (106) to a delivery outlet (109). Water is supplied via the delivery outlet into a receptacle (102) for containing coffee grounds. Heating of water in a heatable section (110) of the tubing generates water vapor bubbles. The one-way valve is arranged to restrict backflow, in a direction away from the delivery outlet, so that the heated water comprising water vapor bubbles is transported in the tubing from the heatable section to the delivery outlet. A sensor (120) senses bubbling in water in the tubing between the heatable section and the delivery outlet. This sensor has been found to facilitate control over how much heated water is carried to the receptacle, and accordingly the amount of brewed coffee produced, in a reliable, compact, and relatively low-cost manner. Further provided is a method of operating such a coffee brewing apparatus, and a related computer program.
