  1. Note: Values of pH, alcohol content and residual sugar concentration were measured using an OenoFoss wine analyser. Total phenolic contents were measured using the Folin–Ciocalteu method, and the results were expressed as gallic acid equivalents. Tannin contents were measured using total condensed tannin and bovine serum albumin (BSA) precipitation methods against a (+)-catechin standard, and results were expressed as (+)-catechin equivalents. For the summary of sensory perception, highlighted attributes have significant (p < 0.05) different mean values of perceived intensity compared to the other group in the continuous scale assessment
