Abstract: A wine inventory management system is provided to assist a user in selecting and locating a wine from a wine collection. In one example, a wine inventory management system may comprise a smart cap having an indicator portion and a processor in communication with the smart cap. The processor in communication with the smart cap may comprise a determining module that determines a set of criteria, a matching module that matches wines to the set of criteria to form a wine set, and an illuminating module that illuminates smart caps of the wine set. The smart caps may be illuminated with different colors, light animation patterns, and with different images in some examples.
