对3种贮酒器(黑陶缸、红陶缸和不锈钢缸)所贮1年原度汾酒,2种不同盛酒瓶(瓷瓶和玻璃瓶)所盛1年商品汾酒和红陶缸所贮1、2、3、5、10、20和30年汾酒中24种金属元素的含量、变化趋势及作用进行了分析。结果显示,3种贮酒器中,对酒质有利的元素在红陶缸中含量最多,黑陶缸次之,不锈钢缸最少;红陶缸短期贮酒老熟效果最好,黑陶缸长期贮酒最有利于酒质,不锈钢缸则适合作周转勾调容器用。2种酒瓶对1年商品汾酒中金属元素的含量有一定的影响,玻璃瓶贮酒更有利于促进酒体老熟,贮存新酒效果更好;瓷瓶贮存老酒效果更好。老酒中金属元素的含量变化与贮存期的长短密切相关,随着贮存期的延长,酒中大部分金属元素的含量整体呈动态增加。长期贮酒5～10年为较适贮存期,短期贮酒3年效果较好,并且贮存过程中可采用间隙贮存加分质分存策略加速老熟,可在短期内达到较好的陈酿效果。

The 24 kinds of metal contents and varying trends were analyzed in Fen liquor from three kinds of aspects which contained one-year original Fen Liquor in three different containers(red pottery,black pottery and stainless steel containers).Specifically,one-year commodity Fen Liquor in two kinds of bottles(porcelain bottles and vitreous bottles),old liquor from one year to thirty years in red pottery containers.Meanwhile,the metal's effect on liquor quality was discussed intensively.The results indicated that,among the three kinds of containers,contents of useful elements for liquor quality were the highest in the red pottery,lower in the black ones,and the lowest the stainless steel cylinder.Red pottery was the best for the liquors' aging and ripe effects;black pottery was the most useful for long-term storage;stainless steel cylinder was suitable for being a turnover and blending container.The two kinds of bottles had specific effects on the contents of metal elements in one-year commodity Fen Liquor.Vitreous bottles were more favorable to speed liquor's aging and especially suitable for new liquor storage;potteries were more suitable for old liquor storage.In addition,it was proved that the variation of the metal-element contents in old liquor was in connection with storage periods,that is,with the increase in the storage period,the majority contents of the metal elements increased totally.5~10 years is the best time frame for long-term storage,3 years for short-term storage,and it was applicable to choose different storage containers in different storage stages in order to accelerate the aging process and gain the old liquor effects within short time period.
