The present disclosure relates to a system for producing beverages or other food products which includes, generally and broadly, controllably dispensing water from the system for use in brewing. Water is introduced to a heated water reservoir heating and subsequent use in a process such as brewing. An active thermal expansion system is provided to accommodate water which expands from the reservoir as a result of the heating process. One form of thermal expansion system may include a controllable expansion device accommodates an accumulation of water which expands during the heating process and then returns the water to the flow of water during a brew cycle or drains the water from the system.
