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.


Sulphite Calculator Online provides most of the same functionality as the downloadable version. In particular, the source code for the online calculator version 1.00 has been translated from version 3.00 of the downloadable calculator. Please read the Sulphite Calculator Manual or contact the author if any assistance is required. Currently the online version does not support the saving of default settings, but the remaining functionality is largely the same as the downloadable calculator. In particular, the calculation results should be identical between the two calculators.
