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 (20) heating and subsequent use in a process such as brewing. A thermal expansion system (86) is provided to accommodate water which expands from the reservoir (20) as a result of the heating process. One form of thermal expansion system (86) may include a venturi device (88) which allows the accumulation of water which expands during the heating process and then returns the water to the flow of water during a brew cycle.
