A system for managing and monitoring a small or large collection of sealed containers, such as wine bottles, barrels, medicine containers, or bags, as well as individual grapes, batches of must, and other liquids, whose contents may be volatile and difficult to access without destroying the seal and the contents or risking contamination of the liquid. The system performs automated monitoring tasks by communicating with specially manufactured bottles or traditional bottles that have had a sensor installed. Sensor installation can be accomplished with unmodified commercialy available equipment.
