A cartridge for dispensing a liquid concentrate/extract includes a hollow body, a dispensing tube that contains a pumping device, and a valve having a valve stem that passes through a port of a valve seat connected to the dispensing tube. The valve stem includes a first end having a piston, and a second end having a valve body in removable contact with the valve seat for alternately opening and closing the port. The piston can include a membrane disposed towards the valve stem and configured to dispense fluid into the dispensing tube when the valve body contacts the valve seat and to forcibly express fluid from the dispensing tube when the valve body is moved from its contact position. A liquid dispenser suitable for numerous applications, having a removably insertable concentrate/extract cartridge and a method of dispensing a liquid are also provided.
