The role of production process and information on quality expectations and perceptions of sparkling wines

BACKGROUND: This study, by combining sensory and experimental economics techniques, aims to analyse to what extent the production process, and the information about it, may affect consumer preferences. Sparkling wines produced by Champenoise and Charmat methods were the object of the study. A quantitative descriptive sensory analysis with a trained panel and non-hypothetical auctions combined with hedonic ratings involving young wine consumers (N = 100), under different information scenarios (Blind, Info and Info Taste), were performed. RESULTS: The findings show that the production process impacts both the sensory profile of sparkling wines and consumer expectations. In particular, the hedonic ratings revealed that when tasting the products, both with no information on the production process (Blind) and with such information (Info Taste), the consumers preferred the Charmat wines. On the contrary, when detailed information on the production methods was given without tasting (Info), consumers liked the two Champenoise wines more. CONCLUSION: It can be concluded that sensory and non-sensory attributes of sparkling wines affect consumers' preferences. Specifically, the study suggests that production process information strongly impacts liking expectations, while not affecting informed liking. © 2018 Society of Chemical Industry.
