What’s the best way to add sulfite to my wine?
There are two effective methods of sulfite addition to wine. Campden tablets are small tablets of sulfite that are a pre-measured dose meant to add 25ppm to 5 gallons of wine. The drawback to these tablets is that sometimes they do not dissolve completely. The most effective way to add sulfites into wine is via powdered potassium metabisulfite. Winemaker Magazine offers a sulfite calculator on their website that is very useful in helping a winemaker figure out an exact dosage of sulfites for their wine. To use this calculator, one must know the volume and pH of the wine to be treated. The average rate of application for potassium metabisulfite is ¼ tsp/5 gallons to raise the sulfites by 50ppm. The sulfite calculator is a better option as it will help you find and exact dosage needed for your wine contingent upon the wines’ pH and stability.
