Sodium Metabisulfite Dosage for Cider
The typical dosage of sodium metabisulfite for cider is 0.44 grams per litre (which provides approximately 50 ppm of free SO2).
- This dosage is suitable for protecting the cider from spoilage organisms and oxidation at most stages of cider making.
- If you are using sodium metabisulfite as a preservative after fermentation, 0.44 grams per litre is a standard, safe amount.
- If your cider is very acidic or contains a lot of fruit solids, you may consider increasing the dose slightly, but do not exceed 1 gram per litre.
Always dissolve sodium metabisulfite in a small amount of water before adding it to your cider for even distribution.
Note: Allow the cider to air out or "degas" after adding sodium metabisulfite before bottling or consuming, as it can produce a sulfur smell if used in excess.
