Wine Stabilizers for Every Stage
Campden Tablets
Campden tablets provide a convenient way to add measured sulfite for wine protection, stabilization, and certain sanitation applications.
Potassium Sorbate
Potassium sorbate is commonly used before back-sweetening to help prevent renewed yeast activity in properly stabilized wine.
Potassium & Sodium Metabisulfite
Metabisulfite helps protect wine from oxidation and unwanted microbial activity while also serving as a common equipment sanitizing ingredient.
Wine Preservation Systems
Wine preservation sprays replace oxygen inside opened bottles with inert gas, helping preserve flavour and aroma after opening.
Choosing the Right Wine Stabilizer
Campden Tablets
Campden tablets are widely used before bottling, after fermentation, and during certain stages of winemaking where sulfite protection is appropriate. They provide a convenient pre-measured dosage for many common home winemaking batches.
Potassium Sorbate
Potassium sorbate is typically used when sweetening finished wine. It does not stop an active fermentation but helps prevent surviving yeast from reproducing after the wine has been properly stabilized.
Potassium Metabisulfite
Potassium metabisulfite helps reduce oxidation while providing antimicrobial protection. It is commonly used throughout winemaking according to the needs of the recipe.
Sodium Metabisulfite
Sodium metabisulfite is frequently used as an equipment sanitizer and is also suitable for certain preservation applications where appropriate.
For a full explanation of how these products differ, including potassium versus sodium metabisulfite, Campden tablets versus powder, potassium sorbate, and Tannisol, see our Wine Preservatives, Stabilizers & Sulfites Guide.
Frequently Asked Questions
What is the difference between potassium sorbate and Campden tablets?
Campden tablets provide sulfite, helping protect wine from oxidation and microbial spoilage. Potassium sorbate helps prevent renewed yeast growth after fermentation has finished. They are often used together when back-sweetening wine.
Can potassium sorbate stop an active fermentation?
No. Potassium sorbate is intended for use after fermentation has completed and the wine has been properly stabilized. It does not stop an actively fermenting batch.
Why is potassium metabisulfite used?
Potassium metabisulfite helps protect wine from oxidation and spoilage organisms while supporting longer storage and ageing.
When should I stabilize wine?
Wine is commonly stabilized after fermentation has completely finished and before back-sweetening or bottling. The exact timing depends on your recipe and winemaking process.
How does a wine preservation spray work?
Wine preservation sprays replace oxygen in the headspace of an opened bottle with inert gas, helping slow oxidation after the bottle has been opened.
