Water is one of important material in brewing beer, whose character also effect beer taste in some way. 


So, what is the basic request of brewing water?

  • Clarity. Water need to be clear and colorless. No suspended solids and sediment. Otherwise, beer is liable to be cloudy.

  • Smell. If heating water to 20-50℃ and water is tasted refreshingly, no peculiar smell, water is workable. If there is saline taste and bitterness in tasting water, it means water is not qualified to brew beer.

  • Dissolving salt content. Suitable salt content is between 150-200mg/L. Higher salt content brings rough taste and bitterness to beer.

  • PH. Reasonable PH scope is 6.8-7.2. Meta-acid or slightly alkaline will not benefit mashing process.

  • Hardness. If brewing light beer, water hardness need to be less than 8°dH(equal to 5.706mmol/L). If rich colour beer, hardness could be raised accordingly.

  • Iron content. Less than 0.3mg/L

  • Chloride. Better between 20-60mg/L

  • Ammonium salt. No any Ammonium salt, otherwise, water is not clear.

  • Silicate. Less than 30mg/L. If exceeding 50mg/L, wort is liable to be cloudy and form micelle in fermenting process, which effects lauter and fermenting.

  • Bacteria. Same to drink water.
