The correlation coefficients between astringency and “green”,
“hay” and “woody” flavors indicate that astringency was significantly
correlated with the “green” flavor of UPAS samples, but not of PAS
samples, and vice versa for “hay” flavor (Table 2), while a “woody”
flavor was significantly correlated with astringency of both UPAS
(r=0.517) and PAS (r=0.679) samples.
