Sodium metabisulfite to clear chloramine
TroubleShooting
Alistair Scriven • Portland, Oregon asks,
I recently moved to a city that uses chloramine in the water supply. Looking for suggestions in removing these chloramines from my brewing water, I posted a question to an online brewing board. It was suggested that adding sodium metabisulfite to the water would clear the beer of this compound. Is this true? How does it work and what would be an approximate amount to add per gallon?
