3.The salt content in the water should be in the level of 150-200mg/L.If the salt content is higher,it will result in rough taste and bitter of beer.
 
4.Ph value between 6.8-7.2, slightly alkaline or slightly acid will make saccharification more difficult and poor beer taste.
 
5.Organics oxygen consumption in the water(for example KMnO4), the organics content lower 3mg/L, the water has beer seriusly contaminated if higher than 10mgL.
6.Hardness in the lower level of 5.706mmol/L if we produce light color beer. If we produce more concentrate color beer, the level of hardness can be increased.
 
7.The content of iron ion should lower the level of 0.3mg/L.
 
8.Ammonium salt should not be existed in the water, if so the water will unclean, in the limit of 0.5mg/L
9.The chorlide content in the level of 20-60mg/L is suitable.
 
10.The silicate content require lower the level of 30mg/L,.If the level higher than 50mg/L, wort will turbid and shape into micelles, even influence the process of yeast fermentation and beer filtration.
 
11The total quantity of bacterial need meet the standard of drinking water.
