Enjoy the beer that you deserve.
What it does :
Silica Gel is used to reduce chill haze-causing proteins, while leaving foam retention and mouthfeel unchanged.
What it is:
Also known in German as Kieselsol, this is a hard, granulated form of hydrated silica, with particles that possess manufactured pores of specified sizes. It is usually available in a convenient liquid form.
How it works:
Silica Gel prevents chill haze by removing haze-causing proteins from the beer.
This additive consists of hollow silica particles, each of which contains a porous honeycomb that invites haze-forming proteins inside. As the particles absorb the proteins they settle out and form sediment at the fermenter bottom for removal.
Use 1 teaspoon per 5 gallons. Add to secondary fermenter 2 to 4 days before bottling or kegging.
The use of Silica Gel in unfiltered beer is not approved by the FDA, who warns that beer treated with it must be decanted before drinking.
Add to secondary fermenter and mix thoroughly.
