e/Campden tablets

Information
has gloss	eng: Campden tablets (potassium or sodium metabisulphite) are a sulphur-based product that is used primarily in wine, cider and beer making to kill certain bacteria and to inhibit the growth of most wild yeast: this product is also used to eliminate both free chlorine, and the more stable form, chloramine, from water solutions (i.e., drinking water from municipal sources). Campden tablets allow the amateur brewer to easily measure small quantities of sodium metabisulphite, so it can be used to protect against wild yeast and bacteria without affecting flavour.
