Access to wine experts' long-term memory to decipher an ill-defined sensory concept: the case of green red wine

The present study aims to understand an ill-defined sensory concept by a long-term memory-based strategy with Spanish winemakers from four wine regions using “green wine” as case study. A total of 77 carried out non-tasting free description task. task yielded terms belonging two main categories including origin-related well terms. Sensory belonged aroma, taste, trigeminal, colour, multimodal and hedonic subcategories, which elucidates the multidimensionality studied concept. most cited specific were “vegetal aroma”, “bitter” “unpleasant”. Despite these commonalities, certain idiosyncrasy linked taste (“excessive sourness”) trigeminal (“astringency”) subcategories components (“tannins”) was evidenced they distinctly experts separate regions. capacity approaches based on memory decipher multidimensional concepts is highlighted. regional effect also explained in cognitive processes (i.e., knowledge experience), use experts.
