An example method comprises receiving a control signal to open a first valve of a compressible liquid container within an airtight pressurized container, retrieving a first dispensing profile, each dispensing profile indicating at least one valve and, for each valve, a predetermined period of time for keeping a particular valve open, each of the valves controlling transport of contents a different compressible liquid container contained within the airtight pressurized container to a dispensing system, for each of the one or more valves identified in the first dispensing profile: opening the particular valve identified in the first dispensing profile for the particular predetermined period of time to transport contents over a first liquid transport conduit that is coupled to a particular releasable coupling and the particular valve, and closing the particular valve after the particular predetermined period of time to dispense an amount of contents of the particular compressible liquid container.
