In a recent study Ellegård, Goldsmith, Hay, and Morton concluded that electrogustometry is neither mediated
by sour taste receptors, nor reflects sour taste quality. While aspects of electric taste await a full explanation, such farreaching
claims have significant implications for the future of electrogustometry in clinical practice. The current paper
presents a critique of the grounds upon which the arguments were based, and suggests that these conclusions may be premature.
