The objective of this research was to investigate the quality characteristics of the spirits by different distillation and filtrations. The contents of alcohol, total acids, and amino acids in rice mash were 15%, 0.25 g/100 mL, and 0.15 g/100 mL, respectively. The soluble content was 10°Brix, and pH was 4.6 in the rice mash. Lactic acid was the most prominent organic acid found in rice mash. The rice spirit distilled by a multi stage distiller showed the highest amounts of aroma compounds, such as fusel oil and esters. However, the filtration did not affect the amounts of total aroma compounds. It is suggested that a multi stage distiller may influence taste and flavor positively by enhancing the aroma and removing the impurities in rice spirits.

This research was carried out to compare the physicochemical characteristics of Korean traditional spirits brewed with Phellinus linteus by different Nuruks. The spirits were produced by atmospheric distillation of rice mash added with 1~5% P. linteus and fermented by traditional and improved Nuruks. Traditional Nuruk facilitated more alcohol production than improved Nuruk during the initial fermentation time. The alcohol contents of rice mash with P. linteus ranged from 15.8 to 18.9%. Predominant volatile compounds were i-amyl alcohol of fusel oils and ethyl acetate of ester compounds in P. linteus added spirits. The spirits prepared by traditional Nuruk showed higher contents of i-butanol, n-butanol, and i-amyl alcohol than those by improved Nuruk. More ethyl acetate was produced in the spirits prepared by improved Nuruk than those by traditional Nuruk. The contents of methyl alcohol were less than 50 mg/L in P. linteus added spirits.
