Abstract
A brewing system which uses an air pump to evacuate a dispensing line and a method of brewing in which a brewer includes an air pump to provide pressurized air at least at the end of a brew cycle to help evacuate moisture from a dispensing line. The brewing system includes a heated water reservoir which retains heated water for dispensing and a dispense line through which the water is dispensed. A vent is coupled to the reservoir. A controllable air pump communicates with the reservoir to controllably add air to the reservoir to drive water out of the reservoir. The vent is closed when the pump is used to add air to the system to allow for a build-up of air pressure in the reservoir and out through the dispense line. The controllable air pump controllably dispenses air into the upper portion. Both the air vent valve and air pump are controllably coupled to a controller.
