Application of an electronic tongue towards the analysis of brandies

This work reports the application of a voltammetric Electronic Tongue (ET) in the analysis of brandies, specifically in its classification according to the scores given by a skilled sensory panel and in the discrimination of different ageing methods. For this purpose, spirits were analyzed with no o...
