Q. Can I leave Sulphite out of my wines?
A: Some people believe that they are allergic to Sulphite, and want to leave
them out of their kits. While this is their option, it's a bad idea. True
Sulphite allergies are terrifically rare, and if someone has a reaction to
drinking wine, it's almost always due to some other cause. Besides, yeast make
Sulphite themselves during fermentation, so no wine can ever be Sulphite-free,
no matter what.
Without added Sulphite the kit will oxidize and spoil very rapidly. It will
start to go off in less than 4 weeks, and be undrinkable in less than three
months. Also, if the Sulphite is left out, but the sorbate is added, the wine
will be attacked by lactic bacteria, which will convert the sorbate into the
compound hexadienol, which smells like rotting geraniums and dead fish.
The bottom line is this: if you do not add the Sulphite to the kit, neither your
retailer, nor Winexpert can guarantee the wine, so think carefully before you do
it.
