It was just pointed out to me that on the Vintner's fruit purees that an instruction may be ambiguous, especially for beginning wine makers. Many of us never read the directions because we have made wine several times.

The Vintner's recipe calls out 1 campden tablet per gallon or 1 liquid teaspoon metabisulphate per gallon. Since the liquid metabisulphate is not readily available the powdered metabisulphate is being used in the same proportion as the liquid. Several wine makers, mainly beginners, have ruined the Vintner's fruit bases by adding this amount. It just will not ferment.

I always try to convince beginners to always use campden tablets. If you insist in using the powder the amount to use is 1/4 teaspoon for 5 gallons.

No matter what directions you are following if you are using chemicals read the chemical label. The manufacturer of the chemical knows the strength of their chemical and label it.

Thanks for the heads up.. Wyo.. Great info..
