In the student wine cellar of the Department of Agriculture in Porec, a separate vinification in 130 L barrels was conducted using the same vinification protocol in order to monitor the development of wine sensory characteristics.. Chemical analyses were performed using the OIV analytical methods. Sensory evaluation of Istrian Malvasia wines was conducted on two occasions, in December 2011 and in May 2012 using a descriptive assessment of wine aromatic characteristics, the order evaluation method, and wine score OIV 100 points evaluation method.
