Divergan®: Create crystal clear beer & wine

There is a simple and clear answer to turbidities: BASF’s Divergan® range! Special Divergan® types help you to avoid haze and create beverages with reduced polyphenol content. 
Easily. Efficiently. Economically.

Divergan® is BASF’s standard processing aid for the filtration and stabilization of beer and wine. Even after filtration, clear beverages contain dissolved phenolic compounds and proteins that, after a relatively short time, form complexes that subsequently lead to turbidity. Divergan® removes phenolic compounds without altering the character of your beer or wine. BASF produces Divergan® by popcorn polymerization of PVP. It is insoluble in water, acids, bases, and organic solvents.

We offer you traditional German brewing expertise combined with knowledge and competence in filtration and stabilization. The result: improved clarity and stability, great appearance, pure taste, and a long shelf life.

While the major applications are beer and wine, Divergan® can also be used in further applications such as fruit juice and tea. Depending on the manufacturing conditions, coarse or fine grain products are obtained, which differ in their application properties.

Divergan® is available as the regenerable grade Divergan® RS mainly used for beer stabilization, and as the single-use grade Divergan® F for beer and wine. 

What makes Divergan® an excellent choice for your products and applications?

  • A unique, patented production process
  • An eco-efficient, single-use and regenerable solution that’s easy and safe to handle and dispose
  • Highly selective adsorption of polyphenols
  • A clean label: Divergan® is completely separated from the beverage during filtration and thus, does not have to be declared on the label
  • Long shelf life and consistently high-quality product
  • More than 150 years of experience in the human nutrition industry and extensive expertise in the application of Divergan®

Going green with Divergan®

Indirect emissions (Scope 3), resulting from upstream processes along the value chain make up the largest share of total emissions for breweries. These emissions are largely from packaging and processing including purchased raw materials from suppliers. Through buying Renewable Energy Certificates (RECs) we have now been able to considerably reduce the product carbon footprint of Divergan®: The use of green electricity reduces the CO2 equivalents (CO2e) for Divergan® by 17%.

Therewith, we support our customers in meeting their CO2 emission reduction targets while we are one step further on our own way to net zero 2050.

The single use solution: Divergan® F

  • Highly selective: Specifically adsorbs phenolic compounds in beer & wine

  • Easy to handle, no lumping

  • Well-defined particle size distribution, homogenous PVPP-structure

  • Designed and developed for pure taste and stability of beverages 

  • Provides longer shelf life by preventing haze

  • Application in existing filter lines possible with high efficiency, even at low dosages.

  • Continuous dosage in addition to the filter aids (e.g. kieselguhr)

  • Combination with filter aids and further stabilizing agents possible 

  • Insoluble in all common solvents, and can therefore be completely and readily removed after use

  • Produced with Renewable Energy Certificates to use green electricity resulting in a 17% lower PCF

Sustainable and regenerable: Divergan® RS
Divergan® RS was specifically developed for use in stabilization and regeneration plants. In normal practice, Divergan® RS is added to the beer from a separate metering vessel after diatomaceous earth (kieselguhr) filtration and separated from the beer in the PVPP filter. The regeneration subsequently occurs in this filter. The small losses arising from regeneration (approximately 1% or less) ensure very low beer stabilization costs. An optimal particle size distribution with low fine-grade fraction, the guaranteed low swelling volume, the high mechanical stability and a qualified technical on-site service ensures trouble-free filtration over an extended period.
 

  • Cost-efficient with low loss rates: where the size of the brewery is appropriate, the instillation of a regeneration plan is worthwhile

  • Highly Selective: Specifically adsorbs phenolic compounds in beer

  • Easy to handle, sustainable product intended for re-use

  • No filter clogging and high permeability, reduced swelling volume

  • High mechanical stability

  • Insoluble in all common solvents, and can therefore be completely separated from the beer by filtration

  • Produced with Renewable Energy Certificates to use green electricity resulting in a 17% lower PCF
