New Chinese rice wine's stimulative taste of ethanol is strong. The hydrogen bonding behavior of ethanol-water system was studied by 1~H-NMR and viscosity tests. Hydrogen bonding strength was measured and compared by ultrahigh pressure technology and different organic acids treatment on ethanol-water system,and organic acid combined with ultrahigh pressure treatment on fresh wines.And the hydrogen bonding association strength was compared with one year aged wine. The results showed that hydrogen bonding str...
