Brewers QCheck® Kit

Brewers QCheck® Kit

The easy way to reliable beer quality!

For more than 30 years, Döhler has been offering culture media for the fast and reliable detection of beverage spoiling microorganisms. Further innovative, ready-to-use culture media are constantly being added to this product range.

With the new Brewers QCheck® Kit, Döhler offers a full solution for the direct detection of beverage spoiling microorganisms in all samples arising in breweries.

Comprehensive quality assurance during the entire brewing process

The Brewers QCheck® Kit makes it possible to carry out microbiological control on all samples in the brewing process – simply, quickly and comprehensively. Different raw materials used in the brewing process, such as water and yeast, can be analysed for microbiological contamination before fermentation.

Beer spoiling bacteria can be detected in the end product, i.e. it is possible to accurately record the beer, and the hygiene of the surrounding area, for example in production, filling or even a dispensing unit.

The Brewers QCheck® Kit is suitable for analysing

  • water and rinsing water
  • yeast samples
  • beer
  • swab samples for hygiene testing in production and dispensing units.

All microbiological findings can be easily and reliably seen through a colour change, even without any previous knowledge. Only minimal laboratory equipment is required. The Brewers QCheck® Kit thus allows the entire beer brewing process to be microbiologically controlled, providing the perfect introduction to microbiological quality control.
