Dehydrated Culture Media for Beverage and Water Testing

To ensure maximum convenience and safety for your microbial water and beverage testing workflow, rely on the superior granulation technology of our dehydrated culture media which meets the highest industry performance standards.

Media granulation minimizes the formation of dust, significantly reducing the dangers associated with fine dust and toxic substance inhalation, to provide a safer work environment.

Advantages of our granulated culture media:

  • Excellent wettability, solubility and free-flowing properties
  • Minimized component separation and clumping, even under warm or humid conditions
  • High batch-to-batch reproducibility
  • Prolonged shelf life of up to five years
  • Granulation allows for inclusion of many supplements, eliminating the need to add these separately

The animal components we use for our media (except some derived from milk) are exclusively sourced from TSE/BSE-free countries and are in accordance with the highest safety standards.



GranuCult® granulated culture media: ISO 11133:2014 compliant

GranuCult Granulated Culture MediaOur GranuCult® low-dust dehydrated culture media granules are compliant with EN ISO 11133:2014 standards, as well as other ISO standards  and FDA-BAM and USDA-FSIS methods for beverages and water sample testing.

Based on a unique granulation technology, our GranuCult® media has superior flow and non-stick properties preventing component separation and clumping.

  • Easy, fast media preparation
  • Free-flowing to help ensure accurate weight
  • High reproducibility and low error rates
  • Minimized airborne particles for safety

Our GranuCult® media are released through an DIN EN ISO / IEC 17025 accredited Quality Control lab. Compliance is clearly visible on the product label and all test strains are listed in the certificate of analysis.




GranuCult® BAT culture media for spoilage testing in juice

The International Fruit and Vegetable Juice Association (IFU) published a revised Method of Analysis No. 12 in May 2019, which gives QC Labs clear guidance for simplified detection, enumeration, and confirmation of Alicyclobacillus spp.. The optional usage of several types of media has been changed to the usage of one liquid (BAT broth) and one solid medium (BAT agar). Our GranuCult® BAT broth and BAT agar offer full compliance with IFU Method No. 12, while providing the benefits of our superior granulation technology listed above.


ChromoCult® chromogenic media

Chromogenic media can provide a rapid alternative method for detecting certain microorganisms. The chromogenic substrates used confer clearly distinguishable colors to different colony types, allowing clear differentiation and identification of the microorganisms present. Our ChromoCult® media can be used to detect a range of microorganisms including Listeria monocytogenes, Cronobacter spp., E. coli and coliforms and, if listed in international standards, they are quality controlled with the same regulatory comprehensiveness as GranuCult® media.




Rapid lemonade spoilage organism broth

RLS Broth (Rapid Lemonade Spoilage Organism Broth) is our newest addition to the beverage spoilage detection portfolio. It is a rapid enrichment medium for the cultivation of beverage spoiling microorganisms. It can be used for all kinds of beverage, base ingredients or swap samples in the soft drink, dairy and winery industry. It is suitable for testing organisms including yeasts, molds, lactic acid and acetic acid bacteria.

Spoiling organisms are often slow growing and tend to be inhibited in soft drinks and wine. This enrichment media enables good recovery and fast growth.


  • Soft drinks: juices, smoothies, syrups and lemonade
  • Raw material for soft drinks: Fruit extracts, flavors, sugars, vitamins, etc.
  • Wineries
  • Dairy industry: all kind of milk derived drinks, for example whey, buttermilk or protein drinks
