Abstract

Three dry red, four sweet red, and two white wines were prepared with domestic grape varieties: Gerbong (G), Campbell Early (C), Muscat Bailey A (M), Seredan (Sd), Seibel (Sb), and Neo-muscat (N). Sample wines were analyzed for titratable acidity, ethanol, pH, sugar content, color intensity and hue, and total phenolic content. Preferences of color, aroma, and overall acceptability were determined by 97 panelists using 9-point hedonic scale. Sweetness, sourness, astringency levels of developed wines were evaluated using 9-point just-about-right (JAR) scale. Mean overall acceptability score of C (6.49) was highest among dry red wines (p<0.05). Among sweet red wines, mean overall acceptability score of Sd (3.27) was significantly lower than those of other wines (p<0.05). In white wines, overall acceptability score of Sb (5.20) was slightly higher than that of N (4.92). Overall sourness levels in dry red wines were higher than optimum level. Based on the results, should be lowered, and sweetness and sourness levels of white wines need to be adjusted sweetness levels of C, G, and Sd for the production of sweer redwines. C and M varieties were considered to be suitable for Korean red wine production.

국내산 거봉, 캠벨, 머스켓 베일리 A, 쉐레단 품종을 이용하여 일반 적포도주와 스위트 와인을 제조하였으며, 사이벨 품종을 이용하여 백포도주, 네오머스켓 품종의 화이트 스위트 와인을 제조하였다. 본 실험의 결과 적포도주 제조에는 캠벨과 머스켓 베일리 A 품종이 타 품종과 비교해 적합한 산도 및 색도를 보였으나, 캠벨의 경우 당 함량이 다소 낮고 신 맛이 강한 결함이 있어 이를 위한 향후 가당 방법 및 포도재배 연구가 필요할 것으로 보인다. 백포도주 제조용 품종인 사이벨의 경우 산도가 매우 높아 발효에 적합하지 않았으며, 신맛의 증가로 인해 기호도가 떨어져 이를 보완할 수 있는 감산 연구가 요구된다. 기호도 조사 결과 품종 별로는 캠벨, 머스켓 베일리 A로 제조된 포도주의 기호도가 높게 나타났다. 향후 선별된 품종을 이용한 포도주의 고품질화 연구가 수행될 예정이며 축척된 제조 기술로 현지의 기술 지도를 통하여 제품의 산업화 및 상품화에 기여하고자 한다.
