초록

본 연구는 가수량을 달리하여 제조된 전통방식의 청주의 발효 및 숙성 특성 변화를 분석하는데 있다. 실험방법으로는 발효 술덧은 3단 담금 하였고 3단 담금시 물을 넣지 않은 청주(A), 1L의 물을 가수한 청주(B), 2L의 물을 가수한 청주(C) 등 3종류의 청주 비교 실험을 진행하였다. 물을 첨가한 청주(B)과 청주(C)가 물을 첨가하지 않은 청주(A)보다 당도, 비중, 산도 및 pH 변화를 분석한 결과 전체적으로 발효력이 우수한 것으로 나타났다. 청주의 숙성($5^{\circ}C$, 6개월)후 아로마 패턴을 분석한 결과, 청주의 주요 아로마 성분인 에틸아세테이트(ethyl acetate)는 가수하여 제조한 청주에서 더 많이 검출되었고 숙성기간동안 그 패턴은 계속 유지되었다. 고급알코올(n-propanol, i-butanol, n-butanol, i-amyl alcohol, n-amyl alcohol)도 가수량이 증가할수록 유의적으로 증가하였고 숙성기간중에 그 패턴을 유지하였다. 유기산 성분은 청주(A)에서 4661.47 mg/L, 청주(B)에서 4873.46 mg/L 그리고 청주(C)에서 4963.12 mg/L 검출되어 가수량이 증가할수록 총산은 증가하였다. 결론적으로 2단 담금에서 물을 첨가하여 제조한 청주가 물을 첨가하지 않은 청주에 비해 우수한 발효력과 품질 및 증가된 아로마를 나타냈으며 물을 첨가한 샘플사이에서는 유의적 차이가 없는 것으로 나타났다.

This present work was aimed to analyse characteristics of fermentation and aging of Korean traditional cheongju prepared by adding of different brewing water. The three different mashes were used for fermentation and maturation. The cheongju(A) was prepared without adding of brewing water in two stage mashing. Cheongju(B) and cheongju(C) were made with adding of 1 liter and 2 liter brewing water in two stage mashing respectively whereas the cheongju(B) and cheongju(C) showed higher fermentation ability than that of cheongju(A) regarding to pH, ethanol, specific gravity and sugar concentration(brix). In terms of volatile compounds content after six months aging, cheongju(A and B) prepared by adding brewing water showed the higher content of ethyl acetate than that of cheong(C) and the concentrations were maintained during the aging period. In addition, the content of fusel oil(n-propanol, i-butanol, n-butanol, i-bmyl alcohol, n-bmyl alcohol)indicated similar pattern as ethyl acetate. The organic acid of cheongju B(4873.46 mg/l) and C(4963.12 mg/l) also indicated the higher content than that of cheongju A(4661.47 mg/l). In conclusion, cheongju B and C prepared by adding brewing water in two stage mashing showed better quality and taste than that of cheongju A.
