Wine aging is a crucial step in the elaboration of special and high quality wines as the sherry and like-sherry type wines are. Some of these wines remain in oak barrels during a long time period, subjected to the “biological aging” process, which is characterized by the maintenance of a yeast biofilm over the wine surface. This yeast’s layer protects the wine from the oxidation and contribute to its specific organoleptic characteristics. This work shows an instrumented bung for monitoring a set of parameters to control this wine aging process. Tests carried out in a winery over 5 months, under real conditions, prove that this device is capable of monitoring key parameters of wine subjected to biological aging in a wireless way, working autonomously for more than a year. •An Iot barrel bung for monitoring wines subjected to biological aging is showed.•The built bung use low cost sensors and wireless communication.•Information provided in real time helps winemakers make timely their decisions.•The IoT bung has been tested along five months under real conditions in a cellar.•The IoT bung contributes to the development of a precision oenology.
