Controlled calcium dosing for perfect brewing results

The targeted adjustment of the brewing water quality is crucial for the brewing process and the quality of the finished beer. Precise dosing of calcium chloride (CaCl2) and calcium sulphate (CaSO4) optimises the pH value in the mash. This results in improved enzyme activity and a fresher flavour of the finished beer.

Challenges in brewing water treatment

  • Excessive residual alkalinity affects the mash pH and consequently impairs enzyme activity.
  • Too low a calcium content can have a negative impact on the settling behaviour of the yeast and disrupt fermentation
  • The result is an unpleasant bitterness and a lack of freshness in the finished beer.
  • A darker colour can be the result of inadequate brewing water treatment.

The solution from sera

The dosing systems from sera enable precise and safe brewing water treatment with calcium chloride and calcium sulphate for a smooth, well-rounded flavour in the beer:

  • Efficient dosing: Our systems enable the precise and safe dosing of calcium chloride (CaCl2) and calcium sulphate (CaSO4) for brewing water treatment. This results in a smooth, well-rounded flavour in the finished beer.
  • Robust design: The dosing systems are made of heat-resistant polypropylene (PP), as CaCl2 is aggressive towards stainless steel.
  • Optimum suspension: An integrated agitator keeps the CaSO4 suspension in suspension and ensures even distribution of the particles.
  • Practical handling: A conical bottom enables complete emptying of residues, while a bag chute makes it easy to add the substances.
