Campden Tablets - Sodium Metabisulfite

Campden Tablets – Metabisulfite for brewing, winemaking, and water treatment.

Campden tablets are especially useful during wine and cider production to protect color, flavor, and aroma during processing and bottling stages.

Usage

Sterilization of wort, wine, or fruit juice

• To eliminate any mold or bacteria, crush and dissolve one Campden tablet per US gallon (3.8L) in a little warm water.
• Stir carefully
• Let the liquid rest for about 24 hours.
  This period allows the SO₂ to:

1. to inhibit undesirable microorganisms
2. to help protect aromas and color
3. to allow time for excess sulfite to dissipate before fermentation

• After the recommended resting time, add your yeast according to your recipe.

Removal of chlorine and chloramine

Recommended dosage

• 1 Campden tablet treats about 20 US gallons (75 liters) of water.

For smaller volumes:

• 1/2 tablet ≈ 40 L
• 1/4 tablet ≈ 20 L

The exact dosage does not need to be ultra-precise for water treatment, but there is no need to add too much sodium metabisulfite.

Usage steps

• Crush the tablet into powder to facilitate its dissolution.
• Add the powder directly to your cold or hot water.
• Stir the water gently to disperse the product well.
• The treatment usually acts very quickly:
• chlorine is neutralized almost instantly
• chloramines often take less than 5 minutes

After that, the water is ready to be used for brewing.

Important usage notes

• Use according to your recipe, winemaking protocol, or brewing instructions.
• The dosage depends on the application, batch volume, and type of beverage.
• Let the treated must or juice rest according to the manufacturer's recommendations before adding the yeast.
• Keep the product well sealed in a cool, dry place.

Campden tablets are a simple, effective, and economical solution to improve the quality of your brews, wines, and fermented beverages while protecting their aromas and freshness.
