    Water is a very important material for Japanese sakes. The quality of water for brewing has a great influence on Japanese sake quality. Many studies have reported on the water for Japanese sake brewing. However, studies on the quality of water used only to dilute Japanese sakes before packing (called Warimizu) are limited. In this report, the effect of the water (Warimizu) on the quality of Japanese sakes was investigated by monitoring their coloring for one year of storage. It was found that some waters sharply promoted the coloring of Japanese sakes during the storage although the color did not increase just after the addition. The effect of water quality on the coloring was investigated by controlling temperature and fluorescence lightening. As a result, it seemed that organic substances like humic acid in the water might promote the coloring of the sakes during storage. It is suggested that organic substances like humic acid found in Japanese sakes through added water (Warimizu) could promote the reaction of the coloring of Japanese sakes as a photosensitizer.
