The aim of this study was to augment previous research by investigating taste perception using a whole food/beverage approach in a case of isolated congenital aglossia, which is the rare condition described by the absence of a tongue without the presence of other syndromes or symptoms. The current randomized, double-blinded study age- and sex-matched a naïve wine taster and sommelier to the 46 year-old female with isolated congenital aglossia. The taste perception of wine was evaluated by measuring 54 variables using a sommelier validated Nose and Palate Survey. Post hoc analysis revealed significant differences in overall palate ratings between the person with isolated congenital aglossia and the sommelier, as well as between the naïve taster and the sommelier for both nose and palate overall ratings (p < .001). There were no significant differences between the person with isolated congenital aglossia and the naïve taster for either overall nose or palate ratings. The results of this study support previous research findings that individuals with isolated congenital aglossia can discern and identify various taste stimuli and suggest that the absence of tongue does not greatly affect wine taste perception in naïve tasters.
