How to Make Wines

Campden Tablets Usage

When you walk over  just a little bit, you will see that there are ingredient kits containing Acid Blend, Yeast Nutrient, Pectic Enzyme, Wine Tannin, Campden Tablets, Pottasium Sorbate and Yeast Pack.
Sulfite has been used since the early days of winemaking as a preservative to protect wines from oxidation and microbial spoilage. For home winemaking, sulfite is commonly sourced from potassium or sodium metabisulfite powder or from sodium metabisulfite tablets, known as Campden tablets. Although potassium metabisulfite Campden tablets are now appearing on the market, they are still not very accessible to home winemakers. Some winemakers prefer adding the potassium form to limit the amount of sodium intake in their diets.
Each Campden fruit-preserving tablet contains four grains of sodium  metabisulphite; therefore, any readers finding Campden tablets in short  supply may ask their chemist for four grains of sodium metabisluphite (or  potassium metabisulphite-there being two forms), and use this. But  because a chemist would find a single order of four grains rather trivial, it  would be best to ask for say, six or ten packets each containing four  grains. If you are making two-gallon lots of wine the amount to use would be eight grains. Do not be tempted to buy by the ounce and  measure out a grain as this is impossible unless you have the appropriate  scales.
