shown). No interaction between salivary flow rate and PROP taster
status with tannin or ethanol was seen, indicating that variation
due to PROP taster status and salivary flow rate did not differ
depending on wine matrix treatment. For taster status, this lack
of interaction with ethanol was not unexpected. Although
Pickering and Robert (2006) found differences in heat/irritation
among red wines to correlate to PROP status, another study
reported data that could not support the argument that taster
status affects the perception of ethanol and ethanol thresholds
(Mattes & DiMeglio, 2001).
