Metal elements in Chinese liquor have significant influence on both liquor quality and human health,and they are also the core elements of micelle formation. The new produced Fen Liquor and the Fen Liquor stored in red pottery vats of Fenjiu group for 1,2,3 and 5 years were selected as experimental materials. Flame atomic absorption spectrometry was used to measure the changes of content of twelve metal elements( Fe,Cu,Zn,Mn,Cd,Cr,Pb,Ni,K,Mg,Na and Ca) which play important effects on liquor quality and human health during the aging process of Fenjiu being stored naturally twice a year with an interval of half a year. As a result,the content of metal elements which were good to liquor quality had a rapid increase rate when the storage period of Fenjiu was 2 ~ 3 years.Conversely,the content of metal elements which were bad to liquor quality had a slow increase rate,and even the increase rate was zero. Thus,all kinds of chemical reactions react actively during this period which was the key period of the formation of micelle in Fen Liquor. Therefore,accelerated aging of Fen Liquor at this period would reduce the aging time of high-quality Fen Liquor. This experiment provides theoretical foundation and scientific value for the right storage of Fen Liquor.
