Does sorbate lose effectiveness over time?

I have a batch of muscadine that will be ready to stabilize and bottle soon,
and I'm wondering whether to use sorbate that I've had for about six months,
or order some more (which may have sat on the shelf at the vendors for six
months...).

Thanks,

Bart

Bart, A general guide line I have been given is to toss after 6-8 months (I
would think particulary if opened, or bagged). But you have a good point
about the wine shop storage conditions. The larger quantities usually come
in a brown medicine style bottle that if sealed, but I imagine it would
depend on where you buy it. Doesn't really answer your question though huh?

Where are you? Muscadine is a NC grape too - one of the oldest.

It does, I have heard the same rule of thumb, pitch it after 8 months.
And I have always wondered how long it sat at the supply house too...


I did have one batch start fermenting in the bottles; no explosions,
just a nice bit of fizz. It was an unhappy accident that turned out
ok. I know it was not too old because I date mine now, but something
happened.

I guess you could look at it this way, you know yours is old, take it
from there...

Southeast Louisiana -- muscadines grow wild around here, plus it's a
commonly planted fruit in backyards. I've got a couple of vines out back,
but the wine I referred to was made with fruit from a neighbor's vineyard of
a dozen or so vines.

Jack Keller's site has a good section describing the shelf life of common
chemicals use in wine making You may have to search for it but it is quite
good.
