Product description

Under its NBB® brand, Döhler offers innovative culture media for the fast and reliable detection of beverage spoiling microorganisms, such as Lactobacilli, Pectinatus and Megasphaera, in all samples that arise in breweries, as well as for the wine industry.

The desire for reliable and easy-to-use cultural detection methods has driven the development of the NBB® culture media, which has been ongoing for 30 years now. Clear and fast detection, a reliable result – even for a very low level of contamination in a large sample volume – and easy application for efficient laboratory work are the key driving forces behind these developments.

That is why renowned customers active in the beverage industry around the world place their trust in this high standard, extensive knowledge and expertise. Publications containing independent investigations and comparisons reinforce the product’s position as the market leader.

With their special growth promotion components and nutrients optimally tailored to beer and wine spoiling microorganisms, NBB® culture media offer a multitude of advantages. Döhler exclusively uses raw materials of non-animal origin, thus eliminating the risk of animal materials entering the beverage quality control process. A series of comprehensive functional tests examine the quality of the NBB culture media with a special panel of test strains, which were all isolated in breweries.

The NBB® portfolio includes the following products:

NBB®-A, Agar

Solid agar medium for pouring agar plates after simple liquefaction 

  • Reduced preparation time by direct liquefaction in the bottle
  • Can be used for membrane filtration, swab and pour plate method as well as for airborne microorganism collection
  • Simple, visual screening by means of an indicator change from red to yellow

NBB®-B, Broth

Liquid culture media with indicator dye for detection of beer spoiling microorganisms in yeast samples or as an enrichment medium

  • Direct use of liquid medium
  • Simple, visual screening by an indicator change from red to yellow

NBB®-C, Concentrated Broth

Liquid culture medium with enhanced selectivity through the addition of yeast-cloudy beer samples.

  • Simply added to the beer sample for analysis
  • Final microscopic inspection, no indicator verification

NBB®-B-AM, Broth

Liquid culture medium for detection of indicator bacteria from biofilms

  • Simple hygiene monitoring for weak point analyses and trending
  • Sampling by means of smear swabs at critical points throughout the production process
  • Direct use of liquid medium - ready-to-use in sterile tubes or sterile bottle for individual portioning
  • Simple, visual screening by means of an indicator change from red to yellow

NBB® culture media offer you the following user benefits:

Flexible formats for immediate use  –  ready-to-use culture media can be used immediately; there is no need for complex weighing of individual components, handling poisonous substances, forming solutions or autoclaving

There is a suitable, optimised NBB® culture medium for every sample to be analysed in the brewing process!
