PurposeThis methodological paper aims to demonstrate the potential benefits of using consumer neuroscientific methodologies to measure consumers’ subconscious responses when consuming wine during a taste experiment. By comparing conscious and subconscious evaluations during a tasting experience this study illustrates how this methodology offers a more nuanced understanding of the consumer evaluation of wine during a consumption experience.Design/methodology/approachThe research made use of a single-case taste test experiment whereby a wine expert blind-tasted 20 white wine varietals. Throughout each tasting, subconscious responses were measured using electroencephalography (EEG), combined with conscious measures of stated preferences using a questionnaire.FindingsStark differences were observed between the results of the conscious and subconscious wine evaluation measures, underscoring the complex nature of consumer decision-making and preference development. This study practically demonstrates the use and value of EEG as a consumer neuroscientific methodology in a wine marketing context.Originality/valueThis paper demonstrates the value of neuroscience techniques in identifying differences in the conscious and subconscious wine evaluation measures. This study practically demonstrates the use and value of EEG as a consumer neuroscientific methodology in a wine marketing context.
