Used in home brewing and winemaking to sanitize equipment. When mixed with water, sodium metabisulfite releases sulfur dioxide (SO2), a pungent, unpleasant smelling gas that can also cause breathing difficulties in some people. As there is now a large number of better and less troublesome sanitizers on the market sodium metabisulphite has fallen from common use.
