Full technical details of use:

NBS BrauSol Special adsorbs sediment-forming colloids. The colloidal silica forms a hydrogel as a result of the reaction with components in the proteins. This creates a coagulate (complex), which is removed from the wort and beer with the insoluble silicic acid, without leaving a residue. Foam, colour, flavour and aroma are not affected.


Application of BrauSol Special in the brewhouse

For optimal hot trub separation, NBS BrauSol Special is added in the whirlpool. Dosing point is, when the whirlpool is full between 75-85%.
Visual inspection: After the dosing in the hot wort, the wort will be for 20 sec. get white; this is the neutral reaction, when the liquid silica sol will be new formulated into a Hydrogel

Very important: No dosing before transfer-pump, otherwise the pump will destroy the coagulate between silica sol and proteins!
The coagulate will be settle down in the whirlpool bottom and will be separated together with the hot trub.

NBS Brausol Special is added at a rate of 0.2-0.4ml per litre.

• accelerates fermentation
• optimizes filter throughput in reduction of haze sensitive proteins • strong hot trub precipitation
• very compact trub


Application of BrauSol Special in the fermentation or during transfer to storage cellar

During this process NBS BrauSol Special is dosed into the cooled finished wort (preferred) or into the fermented beer using a special dosing unit (dosing pump like cleaning detergent dosing) or you put it in the hose (manually), or transfer it in the fermentation tank before cooled wort goes in (via keg).

Dosage: 0.2-0.4 ml/litre cooled wort.

• no impact on fermentation
• yeast crop is increased
• green beer clarifies quicker
• filter throughput during final filtration is increased

The dosage of NBS BrauSol Special during transfer from fermenter to storage cellar provides good results particularly when used in final fermented beer, which is transferred with a temperature around the freezing point (0°C – 10°C).


NBS BrauSol Special complies with the German Purity law regulations and section 9 of the provisional Beer Law. Laboratory tested for purity and quality.

    I’ve been looking for a Vegan alternative for fining my beer for a while now. I’d been using Gelatin and with great results, but Brewing to the Reinheitsgebot I’ve been searching for something else. The results so far are great,added 7ml to my keg line and filled with an amber lager. 10 days in Keg and it’s almost clear, it’ll improve over time. I’m hoping to get good results with a Helles in a few weeks. My only complaint, the syringe is too small, but easily resolved.
