Some form of calcium is often added in the brewhouse. Calcium helps lower mash pH, can improve enzyme activity, reduces oxalate (preventing the formation of beer stone), and increases yeast flocculation and diacetyl reduction. Monitoring calcium concentration in wort can be a tool for consistent beer production
