《礼记·郊特牲》
对于五齐中的泛齐、醋齐，因其混浊，要先用事酒冲淡，再用茅草过滤，使其透明可用。对于盎齐以下三齐，因其较清，不用过滤，只须用清酒冲淡一下就行了。至于郁色，用盎齐来冲淡。
缩酌用茅，明酌也。醆酒涚于清，汁献涚于醆酒；犹明清与醆酒于旧泽之酒也。
Because Fanqi and Cuqi among the Five Qi are turbid, they must first be diluted with sacrificial wine and then filtered with straw to make them clear and usable. Since the three Qi below Angqi are relatively clear, they do not need to be filtered, but only need to be diluted with clear wine. As for Yuqi, it is diluted with Angqi.
