Sulphite Calculator can assist the winemaker in calculating the correct amount of sulphite to add in order to achieve desired free SO2 levels in wine. Many tables have been devised for this purpose, however these tables are relatively inflexible in that each table is normally designed for particular sulphite forms (e.g. 10% potassium metabisulphite solution). These tables may not correspond to the practices of the individual winemaker. With Sulphite Calculator, the winemaker can precisely define the sulphite source, sulphite form, and batch size. The software can then calculate the exact amount of sulphite required in order to obtain desired free SO2 levels. The software is free, subject to the terms of the licence agreement.
