Fermentation and aging time.
A&C, EC1118 yeast imported from Canada; B & D, YA07 yeast isolated from traditional makgeolli in domestic.
All values are mean±SD (n=3).
Values with different capital letters within a row are significantly different by Duncan’s multiple range test (p<0.05).
Values with different small letters within a column are significantly different by Duncan’s multiple range test (p<0.05).
