탁주의 제조과정 중 사입량의 비율을 조절하여 담금 조건을 달리하는 증량 담금법과 3단 담금법으로 탁주를 제조하여 탁주의 품질특성을 조사하였 다. 3단 담금법에서 초기 당도가 높았으나, 발효가 진행됨에 따라 발효 6일차 까지는 10.5oBrix로 서서히 감소하다가, 그 이후 다시 상승하였다. 증량 담금법의 알코올 증가량은 3단 담금법에 비해 초기 발효속도는 완만했으나 발효완료 시 16.0%에 도달한 반면, 3단 담금법은 초기 발효속도가 빨랐으나, 14.9%로 발효가 완료되었다. 초기 아미노산도는 3단 담금법에서는 2.3%로 높았으나, 증량 담금법은 아미노산도가 서서히 증가하여 발효완료시 3.2%였고, 3단 담금법에서는 3.3%에 도달하였다. 증량 담금법에서 Sake meter value (SMV)는 발효 3일차에 -13.1까지 감소하였으나, 그 이후 지속적으로 증가하여 발효 종료시 11.3으로 나타났다. 관능검사 결과 전반적 기호도는 단맛과 쓴맛의 기호도가 우수했던 증량 담금법에서 더 높게 나타났다.

This study was conducted on wine consumers to explore their behavioral characteristics concerning their drinking frequency of wine, wine selection factors, and difficulties in selecting wines. Data were collected during February 19th 2014 to April 20th 2014. Respondents were students who were taking classes about wine at a University located in the Gyeonggido area. Prior to the analysis, wine consumers were classified based on frequency of consumption: those who consumed wine less than once a month were classified as “Tell me consumers”, whereas those who consumed wine once or more a month were classified as “Engage me consumers.” The wine selection factors of the two groups were as follows: ‘label aspect’, ‘taste and aroma’, ‘use purpose’, and ‘price and recommendation’. Regarding ‘label aspect’ and ‘use purpose’, there were significant differences between the two groups. Regarding difficulties in selecting wines, “Tell me consumers” mentioned the following: ‘experience’, ‘price’, and ‘food pairing’. “Engage me consumers” mentioned the following: ‘ability to identify new wines’ and ‘tastes of others who drink with or oneself’. Classifying domestic wine consumers and their behavioral features of drinking frequency of wine can be used for market segmentation of wine consumers.

This study will provide a useful information and suggestions regarding new wine drinkers wine selection attributes and preference on wine producing countries to wine distributors, wine producers and marketers in Korea. New wine drinkers showed high preference on sweet wine, rich aroma wine, matured wine and white wine respectively. Regarding wine producing countries, Germany, France and Chile were rated among the top preferred countries by new wine drinkers. Results showed that the reasons for disliking wines were not being used to it as the top reason followed by wine being expensive and wine not being tastes good.
