NBB® Prepared Culture Media for Beer (Döhler)

Ready-to-use agar or broth

  • Excellent identification of beer spoilage organisms
  • Use with filtered or unfiltered beer and yeast culture
  • Fast results – optimized nutrient combinations for fast growth of spoiling micro-organisms
  • Simple screening – Simple and reliable visual control through a clear change in the indicator color from red to yellow, for easy quantitative and qualitative analysis in almost any NBB® culture media
  • Increased selectivity – Inhibition of the harmless accompanying flora and culture yeast necessary for the brewing process for optimized detection of beverage-spoiling micro-organisms

Suitable for detection in:

  • unfiltered beers containing yeast
  • filtered beers
  • yeast samples
  • water and rinsing water
  • airborne bacteria collection samples
  • swab samples for hygiene monitoring

Detection of spoiling micro-organisms in all types of beer samples, such as Lactobacilli, Pectinatus and Megasphaera. Get clear, fast and reliable detection, even for a very low level of contamination in a large sample volume.

NBB uses special growth promotion components and nutrients optimally tailored to beer spoiling micro-organisms. Döhler exclusively uses raw materials of non-animal origin, thus eliminating the risk of animal materials entering the beer 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.
