The physicochemical properties of dry wine produced from domestic kiwifruit according to production year from 2008 to 2012 were studied. pHs of wine were from 4.02(F wine, production year 2009, sterilized) to 4.11(D wine, production year 2012, non-sterilized) and their acidities were lowest in D wine(0.79%) and highest in F wine(1.18%). All the wines have the same soluble solids of 8 °brix and 12% of alcohol, respectively. The reducing sugar was lowest in A wine(production year 2008, non-sterilized) and highest in D wine. The lactic acid was detected as a main organic acid and the free sugar was detected only fructose. As main flavor components, ethyl acetate and 1-pentanol were detected and their sum of 80~90% and a small amount of phenylethyl alcohol which providing rose-like aroma was also detected. The contents of soluble phenolics were highest in D wine(1.07 g/L) and lowest in C wine(0.80 g/L), corresponding to the antioxidant activity was highest found in D wine according to their soluble phenolic contents.
