A machine for making a beverage such as coffee. A can piercing member is adapted to move up and down relative to a housing having a reservoir in which water can be heated and then passed through the can. The reservoir communicates with a cylinder having a piston, so that the expansion of the water in the reservoir due to heating causes relative displacement of the piston and the cylinder, and this displacement causes the piercing member to perforate the container for the coffee or similar material.
