Doesn sulphite smell bad?
Sulphur dioxide is a poisonous gas with a sharp, pungent smell. If you sulphite a wine at the end of fermentation, to stabilise it and prevent early oxidation, then you should not be in a hurry to drink it. As the wine matures, the sulphite level drops steadily. When the wine is ready for drinking, there should be no discernable sulphur dioxide smell. Sometimes you can smell sulphite in commercial wines, and usually this is because they have been rushed to the market too soon.
