Ammonia

Ammonia is a compound with the chemical formula NH3 and is one of the important indicators when assessing brewing water. If the ammonia concentration in water exceeds 0.1 ppm, contamination by sewage is suspected, and the water is considered unsuitable for brewing. In the sake-making process, ammonia water may be used in the deacidification of sake, and quality control of it is extremely important. In brewing, proper management of ammonia has a significant influence on the balance of flavor and aroma.
