Peleg, 1999 ➔ The more the concentrations of flavan-3-ols increase, the more maximum intensity and perception duration for bitterness and astringency are increase. ➔ Procyanidins fractions having a DPm > to 20 and solubilized in an hydro-alcoholic solution have been felt as astringent (Vidal, 2003). 6 3 06/10/2022 Sensory Approach : Tanins astringency 10 9 Ethanol pH Acide tartrique Astringecy Intensity average 8 7 6 5 4 3 2 1 0 0% 7% 11% 15% 2,5 3,0 3,5 4,0 0 g/L 2 g/L 4 g/L 6 g/L Fontoin, H., Saucier C., Teissedre PL., Glories Y.
