Gli effetti dell'etichettatura sulle scelte dei consumatori di vino

An evaluation of the effects of organic and process certifications on wine consumers by means of sensorial testings. The objective of study was to verify if the organic and ISO certifications inserted on bottle labels influenced consumers’ preferences and their WTP. The problem was faced by using the sensorial test in different environments and with different consumers. The wine was tasted in two different places. One was an organic products fair and the other was a wine fair. The results were: 1) the writing “organic” on the labels had positive effects on both preferences and WTP with consumers who were already interested in organic products and with the other consumers only regarding WTP; 2) in conventional segments of the market the widespreade use of the term “organic” had no negative effects neither on preferences nor on WTP of conventional wines; 3) the widespread use of certified ISO labels had no effects on any of the market segments whereas on others it had positive effects on certified wines and negative effects on non-certified wines.
