Rehmannia glutinosa (RG) is one of the major medicinal crops in Korea. The problem with using it is that it contains many indigestible sugars such as stachyose and raffinose. According to our previous experiments about aging technique, the best conditions for making fermented liquor with RG is adding 6% alcohol and aging at 55℃. First, we counted yeast cell number and found that the most yeast was produced when RG was aged for 8 days and fermented for 2 days. Second, we measured soluble solid content (°Brix) of aged RG with different aging periods during alcohol fermentation using a refractive sugar meter. Unlike the difference in the content of fermentable sugar, there is no difference in sugar content depending on the aging period because there is a factor in the suppression of fermentation in the RG, so that fermentable sugar cannot be consumed more than a certain amount. Third, we compared alcohol content (%) of aged RG with different aging periods after alcohol fermentation using an alcoholometer. When aged for more than 5 days, ethanol content increases dependently in aging periods, representing 7.3% alcohol production. What should be considered in future research is that RG has factors that hinder fermentation.
