How to Make Wines

How much Campden Tablets ?

When first preparing a must, I add 1 campden tablet per gallon when I add my pectic enzyme powder. This kills any wild yeast which my be on the skins of the fruit. At each rack I add ½ to 1 campden tablet per gallon. The fermentation helps protect the wine. After fermentation is complete, I rack it a final time and put it in a cool place to settle and clear. At this final rack I add 1 Campden tablet per gallon. I also often add a further ½ tablet per gallon at bottling, for wines which I fear could oxidize easily (i.e., low acid wines). It is perfectly acceptable, however, to add as many as two Campden tablets per gallon at every racking, up to four tablets per gallon total. Although I find this excessive.
