Made from potassium metabisulphite, Campden Tablets were originally developed in the town of Chipping Campden in England to preserve fruits and vegetables.  The Boots Company was the first to market them as a convenient way to accurately sulphite wine.  Sulfur Dioxide, or SO2 “Sulfites” inhibit wild yeast and harmful bacteria in the 24 hours prior to fermentation to give your special wine yeast the competitive advantage, eliminate chlorine, and slow oxidation just prior to bottling. Some commercial wines contain over 1000 ppm sulfites.  Yuck.  Lets make our own wine and try to keep the final SOin the range of 150-300 ppm.  Also useful for dechlorinating water use 1 tablet per 20 gallons.

Wine yeast is selected for resistance to as-directed doses of sulfites.  Recommended usage is 1 tablet per 1 gallon of wine.  As soon as you put your crushed fruit in the primary, add one crushed tablet per gallon.  Crush the tablet(s) and dissolve in a little water then stir them in.  A spoon in a teacup makes a good crusher.  Stir, cover, and wait 24 hours before adding the yeast.  Contact with liquid releases sulphur dioxide, which inhibits the growth of undesirables.  Each tablet imparts 30 ppm of free SO2 leaving 75ppm total behind.  May be used every other racking and at final racking to retard oxidation.
