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.
