Popular questions
How much potassium metabisulfite per gallon of wine?
About 0.3 g per US gallon (≈50 ppm as SO2), or 1 Campden tablet per gallon; adjust to wine pH and confirm with a free SO2 test.
How much potassium metabisulfite per gallon of mead?
Start with ~0.3 g per US gallon (≈50 ppm as SO2), or 1 Campden tablet per gallon; mead’s typically higher pH may require more to reach the target molecular SO2, and stabilization often also uses potassium sorbate.
Is potassium metabisulfite harmful?
At permitted food levels it’s generally considered safe, but sulfites can trigger asthma or allergic‑like reactions in sensitive individuals; the powder/solutions are irritating, so avoid inhalation and skin/eye contact.
When to add potassium metabisulfite to wine?
Add at crush to limit wild microbes and oxidation, then maintain appropriate free SO2 after fermentation during aging/racking and just before bottling based on pH.
How much potassium metabisulfite per gallon?
About 0.3 g per US gallon (≈50 ppm as SO2), or 1 Campden tablet per gallon; measure free SO2 and adjust for your beverage’s pH.
What does lysozyme do?
It acts as an antimicrobial preservative by breaking down bacterial cell walls (especially in Gram-positive bacteria), helping prevent spoilage and defects and extending shelf life.
What is a lysozyme?
An enzyme (muramidase), usually derived from hen egg white, approved as food additive E1105 and used to inhibit the growth of certain bacteria in foods.
Where is lysozyme found?
Naturally in egg white, human tears, saliva, and milk; in foods, it’s added to some cheeses and wines as a preservative.
Is lysozyme an enzyme?
Yes—it's an enzyme that hydrolyzes bonds in bacterial peptidoglycan, weakening their cell walls.
What foods contain lysozyme?
Some hard and semi‑hard cheeses and certain wines that use it to control lactic acid bacteria; where required, labels may list “lysozyme (from egg).”
