Abstract
Madeira wine is a fortified wine produced in Madeira Island, Portugal. Its characteristics are strongly influenced by the winemaking method used which includes a typical and unique step called estufagem. This process consists on heating the wine up to 55 ºC for at least 3 months. In this paper, the characterization of the sensor for the pilot scale facility of estufagem installed in Madeira University is presented, being the device an optimization of a previous version. The response of the sensor was tested towards colour and refractive index, showing a good performance. Madeira wine with different estufagem times was also analysed.
