How to Use This Calculator
- Enter Wine Volume, Current Free SO₂, and Target Free SO₂.
- Set Wine pH.
- Review Potassium Metabisulfite (grams) and Antimicrobial Protection.
- Use KMS (teaspoons) (tsp) and Campden Tablets (tablets) to inform your decision.
- Use the chart to visualize the results and explore different scenarios by adjusting inputs.
