사과 증류주(apple One spirit) 숙성에 있어서 국산 참나무의 품종이 fine spirit숙성 술통재로서의 적성여부를 검토하는 기초적 연구의 일환으로 본 연구를 실행하여 다음과 같은 결과를 얻었다. 1. 양조 원료를 대체 할 수 있는 과실로서 현재 대량생산 되는 과실의 화학분석 결과는 다음과 같다. 사과 : (Apple) (Malus pumila Miller var domestica Schneider) 중 홍옥(Jonathan)은 총당 13.95%, 총산 0.46%, 휘발산 0.012%, pectin 0.20%, 국광(Ralls)은 총당 13.35%, 총산 0.43%, 휘발산 0.011%, pectin 0.455%이었다. 2. 사과중에는 당분과 산 이외에 cellulose, pectin, hemicellulose 등 때문에 사과즙수을이 떨어짐으로 Aspergillus niger SUAFM-430의 xylanase와 amylase, Aspergillus niger SUAFM-6의 cellulase, pectinase를 사과즙에 처리하여 사과즙의 수율을 향상시켰다. 그리고 이황산 처리로 과즙중 여러 미생물을 살균하고 배양효모로서 발효능이 우수한 sacharomyces cerevisiae var. ellipsoidens Rasse Johannisberg II (SUAFM-1018)을 사용하여 사과주를 양조하였다. 사과주(Apple wine)는 원료에 대한 수율이 $86{\sim}87%$이고 Jonathan, Ralls가 ethanol 13.5%, extract분 5.4%, methanol$0.04{\sim}0.05%$이었다. 3. 사과주의 증류수(fine spirit) 제조는 단식증류법(Pot still)으로 2회 증류로서 실험하였다. 사과(apple) fine spirit는 apple wine mash에 대한 수율이 86.6%이고, 홍옥(Jonathan) fine spirit는 pH 4.1, 국광(Ralls) fine spirit는 pH 4.2이었다. 4. 사과주를 증류하여 제조한 fine spirit를 숙성시키기 위하여 국산 참나무 24품종을 나무의 심재(心材) (Inner part)와 변재(邊材) (Outer part)를 사용하여 fine spirit의 숙성융통제를 선발하는 실험을 하였다. 참나무 24품종과 그의 심재, 변재 별로 참나무의 절편(oaa chip) $(1{\times}1{\times}5cm)$을 만들고 oakchip 2개를 각 fine spirit 300ml씩 들은 640ml용맥주병에 담그고, 6개월간 숙성시키면서 색, 향기, 맛 등을 조사하였다. A. 숙성용술통재 선발의 1차 screen결과로서 색추출속도가 우수한 참나무 품종은 다음 순서와 같다. 갈참나무(심재) Quercus aliena Blume(Inner part), 굴참나무(변재) Q variabilis Blume (Outer part), 갈참나무(변재) Q. aliena Blume (Outer part), 졸참나무(심, 변재) Q. serrata Thumb (Inner & Outer part), 신갈참나무(변, 심재) Q. mongolca Fisher (Outer & Inner part), 상수리 나무(변, 심재) Q. acutissima Carruthers (Outer & Inner part)의 순서등 5품종을 선정하였다. B. 숙성온도별 영향으로서 실온 $24{\sim}25^{\circ}C,\;30^{\circ}C,\;45^{\circ}C$ 별로 각 fine spirit에 oak chip을 넣고 숙성시킨 결과 $45^{\circ}C$에서 숙성시킨 것이 가장 숙성이 촉진 되었고 다음이 $30^{\circ}C$, 다음이 실온에서 한 순서의 경향이었다. C. 투명한 삼각후라스크에 각 fine spirit에 oak chip을 담그고 자외선 조사를 하여 3개월간 숙성 시켰드니 숙성효과가 contral구 보다 거의 2배가 촉진하는 흥미있는 사실을 확인하였다. D. 사과주에서 증류한 fine spirit 300ml에 2개의 oak chip을 담그어 숙성시킴에 있어 oak chip의 여러성분이 fine spirit에 용출되여 나오는 정도가 fine spirit의 pH에 중요한 관계가 있음을 알았다. E. 선정된 5개 품종의 oak chip과 블란서 참나무 술통재(Limousin white oak from France)를 control로 하여 각 사과주를 증류한 fine spirit에 2개의 oak chip($1{\times}1{\times}5cm$)을 담그고 실온, $(24{\sim}25^{\circ}C)$, $30^{\circ}C,\;45^{\circ}C$, 실온에서 자외선조사 하면서 각각 6개월간 매일주일 마다 진탕하면서 숙성시켰다. 6개월간 수성시킨 fine spirit(young brandy)의

This research was carried as a part of the basic study, in which the aptitude of theKorean oak varieties as barrels for aging apple fine spirits was investigated, and thefollowing results were obtained. 1. Following was the result of the chemical analysis of the fruits which are now mass-produced and can be used as a substitute for raw materials for wine production. Apple (Malus pumila Miller var. domestica Schneider) : Total sugar. total acid, volatile acid and pectin of Jonathan (Hong-og) were 13.95%, 0.46%, 0.012%, 0.20% respectively. Total sugar, total acid, volatile acid and pectin of Ralls (Koog-kwang) were 13.35%, 0.43%, 0.011%, 0.45% respectively. 2. Because of low yield of apple juice due to cellulose, pectin, hemicellulose which are present besides sugars, acids in apples, the apple juice were treated with xylanase of Aspergillus niger SUAFM-430, cellulase and pectinase of Aspergillus niger SUAFM-6. This treatment increased the yield of apple juice. And the apple juice was sterilized by adding potassium metabisulfite $(K_2S_20_5)$ and Saccharomyces cerevisae var. ellipsoideus Rasse Johannisberg II (SUAFM-1018) as a cultivation yeast, which has a strong fermentation power was used to ferment. The yield of apple wine based on raw material was 86-87%. The amount of ethanol, extract and methanol obtained from Jonathan and Ralls were 13.5%, 5.4%, 0.04-0.05% respectively. 3. Wines were distilled for two times by the pot still method to make fine spirits. The yield of fine spirits from apple wine mash was 86.6%, and the pH of fine spirits from Jonathan and Ralls were 4.1, 4.2 respectively. 4. The oak chips made of inner part or outer part of 24 Korean oak varieties were used to select the barrel for aging fine spirits. Two oak chips (one oak chip: $1{\times}1{\times}5cm$) of the inner part or of the outer part of each oak variety were dipped into 300 ml of fine spirits, which was bottled in 640ml beer bottle, and followed aging. The colors, flavors and tastes of the fine spirits were checked during 6 months. A. As a criterion for the first screening of oak barrels for aging fine spirits, the rate five of color extraction was determined. The oak chips showed good results in their order as follows and the best 5 varieties were selected. Gal-cham: Quercus aliena Blume (Inner part), Gul-cham: Quercus variabilis Blume (Outer part), Gal-chain: Quercus aliena Blume (Outer part), Jol-cham: Quercus serrata Thumb (Inner and Outer part). Sin-gal-cham: Quercus mongolica Fisher (Outer and Inner part) Sang-su-ri: Quercus acutissima Carruthers (Outer and Inner part) B. To find out the influence of aging temperature on aging, apple fine spirits were aged by dipping each oak chip at room temperature $(24-25^{\circ}C)$) and $45^{\circ}C$. Aging at $45^{\circ}C$ gave the best result followed aging at $30^{\circ}C$ and then at room temperature. C. Apple fine spirits was aged for six months by dipping oak chips in Erlenmeyer flasks and was irradiated with U.V light. The U.V irradiation enhanced the aging effect by nearly two times, compared with the aging without U.V irradiation. D. In aging apple fine spirits by dipping two oak chips, it was observed that the extent of the extraction of most components of oak chips were strongly dependent upon the pH of fine spirits. E. Oak chips of five selected oak varieties and a Limousin white oak from France as a control were used. Each apple fine spitits was dipped by two oak chips, and was aged at room temperature $(24-25^{\circ}C)$, $30^{\circ}C$, $45^{\circ}C$, and with the U.V irradiation at room temperature shaking every week. After six months of aging, the panel test of these aged fine spirits (Young Brandy) showed the following result. Young brandy of apples aged at $45^{\circ}C$ by dipping oak chips of Gal-chain was almost as the fine spirits which were aged at room temperature by dippin
