How Much Sodium Metabisulfite per Gallon of Cider?

The general guideline when using sodium metabisulfite to stabilize or sanitize cider is:

  • 1/4 teaspoon (approx. 1.3 grams) per 5 gallons of cider
  • This equates to about 0.05 teaspoon (about 0.26 grams) per 1 gallon of cider

This dosage will provide approximately 50 parts per million (ppm) of free SO2, which is typical for sanitizing and stabilizing cider.

Instructions:

  • Dissolve the sodium metabisulfite thoroughly in a small amount of water before adding it to your cider for even distribution.
  • Adjust the dosage if your cider has unusually high or low pH, as needed for stability.

Always measure carefully and use as directed to avoid affecting flavor.
