Liquid silica sol CraftSol 1 kg

CraftSol is a highly concentrated liquid silica sol designed to improve wort and beer clarification without the need for filtration. Thanks to its high charge intensity within the brewing pH range, it rapidly adsorbs haze‑forming protein fractions (12–60 kDa). The colloids responsible for haze are removed as a complex with insoluble silicic acid, without affecting foam, colour, taste or aroma.

CraftSol can be applied at different stages of the brewing process: in the brewhouse, at the start of fermentation or on green beer. It improves flocculation, accelerates clarification and optimises filtration performance. The product complies with the Reinheitsgebot and §9 of the German Provisional Beer Law.

Why choose this product?

• Efficient clarification without filtration through selective protein adsorption.
• Compatible with hot wort, cold wort, fermentation and green beer.
• Preserves foam, colour and aroma of the final product.

Technical Tips

• For dry‑hopped beers, add CraftSol before hop addition to improve essential oil yield.
• On green beer, CraftSol improves filtration flow and reduces kieselguhr consumption.
• For bottle‑ or cask‑conditioned beers, ensure sufficient viable yeast remains for secondary fermentation.
