This invention is a manually operated beverage brewer that is powered by a user articulating or turning a lever a multiple of times. The lever forces a small piston into a cylinder, which in turn pressurizing a hot liquid poured into the machine. The pressurized liquid flows through a pack of coffee grounds and out of the machine after the user has generated a minimum pressure to overcome an under-pressure valve. The user continues to articulate or turn the lever until the desired amount of coffee exits the machine.
