Silicates are abundant in the barley husk and they are soluble as colloids. The presence of silicates is are correlated with beer haze.[1]
Silica is ubiquitous in water supplies, and can also be extracted as silicate from grain husks. High levels can slow lautering and haze in beer.[2]
Is excessive silica is extracted from grain (e.g. from sparging at a high pH), it can impair fermentation.[3]
