Microbiological stability in beer: tailored testing for long-lasting quality
Microbiological stability is a key parameter for ensuring the long-term quality and safety of beer. Preventing contamination by unwanted yeasts or bacteria helps preserve its organoleptic properties and ensures a shelf life aligned with market expectations.
The Centro Analisi CAIM laboratory, drawing on extensive expertise in the beverage sector, offers a dedicated service for assessing the microbiological stability of all types of beer – from craft brews to industrial-scale production.
Using rapid and reliable analytical methods, we detect the presence of spoilage microorganisms – such as wild yeasts, lactic acid bacteria, acetic acid bacteria, and others – which may escape standard quality control procedures. The service is structured into two main phases:
- Microbiological analysis after incubation: carried out under conditions that favour the growth of latent contaminants.
- Comparative organoleptic analysis (pre-/post-incubation): used to assess sensory changes, including turbidity, off-odours, off-flavours, and other defects.
This approach simulates in the lab what happens to the product over time, enabling the early identification of potential issues.
The analyses can be customised based on:
- the type of beer (unpasteurised, bottle-conditioned, filtered, etc.),
- the production process,
- the intended shelf life.
Our mission is to support breweries and bottlers in preventing microbiological issues, enhancing product quality, and reducing risks during distribution.
Our laboratory is fully operational and ready to deliver a fast, accurate, and tailor-made service that meets the highest quality standards.
