Beer Processing
Beer processing consists of three main steps: brewing, fermentation and clarification. In the third step, microfiltration plays an important role in producing a quality product. Control of particulate and microbial levels is essential in order to maintain the consistency and the quality of your beer.
Production processes differ by the type of beer and applications. We provide you here below with a genral wine process that you can adapt to your specific requirements.

About Beer Processing
Yeast Propagation
After the sugar solution has been prepared in the brewing house, yeast is added. This single-cell micro-organism will absorb simple sugars and turn them into carbon dioxide and alcohol. The taste of your beer is determined by the beer yeast culture, due to the different range of esters that are produced.
The purity of the yeast strain used to produce the beer is really a key to the quality and the consistency of your beer. The air vented in the container of the yeast propagation before pitching must be free of microorganisms in order not to spoil the culture.
Trap Filtration
Trap filtration is a necessary step to retain diatomite particles and PVPP fines after diatomite filter clarification and the PVPP stabilization.
Cold Sterile Filtration
Cold sterile filtration is an alternative technology to thermal pasteurization. Pasteurization is a traditional method used to inactivate spoilage bacteria and that is based on heating the product to a specific temperature for a determined period of time. However, the risk is to damage the flavor with the heat treatment. Sterile filtration effectively removes the spoilage microorganisms, but without damaging beer’s flavor. It allows your beer to be processed safely, while maintaining its freshness. After the three filtration steps, particles and micro organisms that could spoil your beer are removed.
Carbon Dioxide Adjustment
It is specific to beer processing. It is not just the addition of carbon dioxide, it is more adjusting the level of carbon dioxide as gas is already present in beer due to the fermentation process
Filling : Bottle Washer and Bottle Filler
Rinse water polishing ensures a good microbiological and particulate quality of the bottle prior to filling. The water you will use for water jetting has to be free of contaminants.
