Description
CAMPDEN TABLETS
POTASSIUM METABISULFITE (KMS)
For Winemaking • Cidermaking • Meadmaking • Brewing
DESCRIPTION
Cellars Choice Campden Tablets provide a convenient, pre-measured source of potassium metabisulfite (KMS). When dissolved, potassium metabisulfite releases sulfur dioxide (SO₂), which helps protect wine, cider, mead and other fermented beverages against oxidation and unwanted microorganisms.
Ideal for small-batch winemaking, each tablet provides an easy, consistent method of adding sulfite without weighing small quantities of potassium metabisulfite powder.
USES
• Helps control undesirable wild yeast and bacteria in juice and must before fermentation.
• Helps protect wine, cider and mead against oxidation and microbial spoilage.
• May be used during racking and aging when additional sulfite protection is required.
• May be used before bottling when appropriate based on pH and free SO₂ levels.
• Can be used to help remove chlorine and chloramine from brewing water.
GENERAL DOSAGE
1 tablet per 1 US gallon (3.8 L) provides approximately 65 ppm sulfur dioxide (SO₂).
Common Batch Sizes
1 US gal / 3.8 L — 1 tablet
5 US gal / 19 L — 5 tablets
6 US gal / 22.7 L — 6 tablets
23 L — approximately 6 tablets
Dosage requirements can vary according to the beverage, pH, existing free SO₂ level, fruit condition and stage of production.
For finished wine or cider, measure free SO₂ and pH whenever possible and adjust additions accordingly.
DIRECTIONS
Crush the required number of tablets into a fine powder. Dissolve thoroughly in a small amount of cool water, juice, must or wine. Add to the batch and mix thoroughly.
For pre-fermentation treatment of juice or must, add the appropriate dosage and allow approximately 12–24 hours before inoculating with a selected wine yeast.
For additions during aging, racking or before bottling, determine the existing free SO₂ level whenever possible before treatment.
IMPORTANT: If malolactic fermentation is intended, excessive SO₂ may inhibit malolactic bacteria. Manage sulfite additions accordingly.
INGREDIENT: Potassium Metabisulfite (KMS).
CAUTION: Contains sulfites. Avoid breathing dust. Avoid contact with eyes and skin. Do not consume tablets directly. Keep out of reach of children. Use only as directed.
STORAGE: Keep tightly sealed in a cool, dry location. Protect from moisture and excessive heat.

FYI – The name Campden tablet comes from the town of Chipping Campden in Gloucestershire, England, where the original solution was developed in the 1920s by the Fruit and Vegetable Preserving Research Station.
