The solution for fighting microbial contamination in breweries 

Simple and comprehensive solutions to prevent microbial contamination in breweries, with on-site testing devices, mobile applications and a personalised consulting service

If you know a brewer or are one yourself, you know that cleaning is a major part of brewing. Whether you are a one-person craft brewery or a multi-site producer, hygiene management is an essential part of your business. 

The application of a good Cleaning In Place (CIP) system in keeping with the recommendations of equipment and hygiene product manufacturers is good brewing practice, but the concentration of production steps in the same permanently humid environment is conducive to microbial recontamination. Furthermore, low-level contamination during packaging can impact the quality of your beers and your reputation.

Managing all the risks can be daunting, but many brewers are so close to the workings of their brewery that their observations and insights naturally lead them to the trouble spots. We offer solutions for all types of production to help you turn your insights into knowledge. 


We offer turnkey services adapted to specific situations

nomad On-Site Microbial Test Kits fit in your pocket, allowing you to test directly at the brewery, where it matters most, in minutes and with minimal effort.

Intuitive and smart applications

With nomad Smart Microbiology Apps, monitoring and managing results is as easy as scanning a QRCode. Automatic colony counting, customised alert levels and other features provide greater visibility.

Personalized support

Microbiological monitoring experts are available to help you set up and implement the right sampling plan for your equipment and recipes.


Compared to other industries, the brewing industry is subject to more diverse and higher risks of contamination than others. Preventive measures exist but are sometimes difficult to apply effectively at all critical points. The implementation of a monitoring plan helps to ensure that they are effective as well as to identify the critical points to be cleaned regularly. 


  • Microbial risks: Water stagnation – Pseudomonas, Enterobacterium, Cladosporidium… 
  • Consequences: Formation of biofilms 
  • Prevention: Design and maintenance of water treatment system, short storage at low or high temperature


  • Microbial risks: storage conditions, rodents – Fusarium, Lactobacillus…
  • Consequences: Mycotoxins inhibit yeast, flocculation, over-foaming… 
  • Prevention: Store dry and at low temperature, protection against pests 


  • Microbial risks: Cleaning water, cross-contamination from other equipment and the environment – Water flora, lactic acid bacteria, enterobaceriaceae, Gluconobacter
  • Consequences: Production of acetaldehydes, diacetyl… 
  • Prevention: Physical separation/distancing between equipment, maintenance, NEP/CIP,

Heat exchanger

  • Microbial risks: Incomplete cleaning – Enterobacteria, Lactobacilli, Pediococci, Yeast 
  • Consequences: Unpleasant flavours, inhibition of Saccharomyces 
  • Prevention: NEP/CIP – rapid fermentation after cooling 


  • Microbial risks: Incomplete cleaning-disinfection, periods of non-use, introduction of ingredients – Hop-resistant Lactobacilli, Paediococcus, acetic acid bacteria, Zymomonas (if sugar added). 
  • Consequences: Acidification, cloudiness, unpleasant aroma.
  • Prevention: NEP/CIP, limited environmental exposure, drying between uses


  • Microbial risks: Cleanliness of equipment and containers (drums, bottles) – Flora described above, formation of biofilms
  • Consequences: Reduction of microbial stability 
  • Prevention: pasteurisation (infrequent)
