Abstract

The domestic grape, cultivar Campbell's Early, was investigated for suitability for production of red wine. The factors for red wine fermentation and quality such as concentrations of sugar, acidity and organic acids in the fresh fruit and the wine from the grape were analyzed. The average concentration of sugar in the fruit was 14%. Since the concentration was not sufficient for fermentation, sugar was added up to 23%. It resulted in production of wine with 12% of alcohol. The total acidity and pH of the fruit were 0.8% and pH 3.4 respectively. Those were optimum levels for fermentation. The fruit contained 3,649 ppm of tartaric acid, 5,339 ppm of malic acid and 948 ppm of citric acid. The wines from Icheon and Youngdong, which were fermented from the grape and M wine which was an imported red wine, were tested. Their pH were 3.5, 3.4 and 3.7, and total acidities were 0.75%, 0.71% and 0.57%, respectively. They contained 1,881 ppm, 2,098 ppm and 8,534 ppm of tartaric acid, 3,033 ppm, 1,952 ppm and undetectable amount of malic acid, 769 ppm, 389 ppm and undetectable amount of citric acid, and 3,337 ppm, 2,368 ppm and 11,991 ppm of lactic acid. This results indicated that M wine contained much more amounts of tartaric acid and lactic acid than the wines of Icheon and Youngdong. The sensory analysis showed that Korean students preferred Youngdong and Icheon wine to M wine. The analytic results indicated that the domestic grape, cultivar Campbell's Early, is suitable source for high quality red wine.

국내에서 주로 재배되는 포도 품종 Campbell's Early의 산도, 당도 및 유기산등 포도주 발효에 관련되는 화학적 성분을 분석하고, 이 포도로 제조된 적포도주의 성분을 분석하여, 본 포도의 적포도주 생산의 재료로서의 적합성을 시험하였다. 각 포도생산 지역에서 수확된 포도를 수확기간인 8월 21일부터 9월 6일 까지 5일 간격으로 분석한 결과 당도는 평균 14%로서 포도주 발효에 충분하지 못하여 설탕을 가하여 23%로 보충한 결과 alcohol 함량이 12%인 포도주로 만들 수 있었다. Total acidity는 평균 0.8%로서 적합한 수준이었고 산도는 pH 3.4로서 적당하였다. 유기산 함량은 tartaric acid는 3,649 ppm, malic acid는 5,339 ppm, citric acid는 948 ppm이었다. 포도주는 이천과 영동에서 국내산 Campbell's Early 포도를 발효 후 1년간 숙성시킨 적포도주를 사용하였고, 대조구로 외국에서 수입된 적포도주인 M포도주를 사용하여 비교하였다. 포도주의 분석 결과 이천, 영동과 M포도주의 순서로 산도가 각각 pH 3.5, 3.4, 3.7이었고, total acidity는 0.75%, 0.71%, 0.57%이었고, alcohol 농도는 모두 12%이었다. 유기산의 농도는 tartaric acid가 1,881 ppm, 2,098 ppm, 8,534 ppm이었고, malic acid는 3,033 ppm, 1,952 ppm, 0ppm이었고, citric acid함량은 769 ppm, 389 ppm, 0 ppm이었다. Lactic acid함량은 3,337 ppm, 2,368 ppm, 11,991 ppm으로 M포도주는 tartaric acid와 lactic acid의 함량이 높은 반면 malic acid와 citric acid는 거의 없었다. 관능시험에서는 선호도에서 영동포도주가 가장 높았고 다음이 이천, M포도주 순으로 낮았다. 따라서 국산 Campbell's Early 포도는 적포도주 재료로 우수한 것으로 보인다.
