Grain and brewing characteristics in some rice varieties

This experiment was conducted to examine the characteristics of brewing rice for the basis of varietal improvement. Among all tested varieties, 1000-grain weight was over 25.4g at nine varieties except five varieties such as Mangeumbyeo, and expressivity and degree of white core in rice grain were respectively over 75.0 and 48.7 percent at eight varieties such as Yangjobyeo. The highly chalky varieties showed low amylose content, low hardness and high water absorption ratio in rice grain. Highly chalky varieties showed higher liquifying power, saccharificating power, baume, total acid and sugar content and rice wine production ratio, but lower alcohol content and residue/wine ratio compared with the other ones.
