World-famous liquors are mostly distilled(Whisky, Brandy, Kaoling liquor, Tequila and Vodka). A cup of Andong Soju(50ml) is about 3,000 won and can achieve 15 times higher value-added improvement than those of 200 won for 100g of rice. The study is about distilling characteristics and ripening of distilled liquors in the condition of normal pressure and decompression by using stainless distiller. Ordinary kind of distilled liquor was distilled in pressures 50cmHg and 60cmHg and normal pressures 90℃ and 80℃ respectively and then was stored in jars and stainless drums and its ripening was observed. As a result, for ripening by 60 days, volatile acidity in jars was high in decompression and the highest value was 0.059% in decompression 60cmHg. In addition, for TBA(Thiobarbituric acid), acidification according to ripening, it was low in normal pressure and at normal pressure 80℃, the value was 182.95. For stainless containers, it showed similar volatile acidity with that of jars. However, its TBA was higher than that of jars and in particular, in case of normal pressure 80℃, it was 300.96.[This research was supported by High Value-added Food Technology Development Program(312011-05-1-HD020), Ministry for Food, Agriculture, Forestry and Fisheries, Republic of Korea]
