I have a welches concord 6 gallon going for the wife. SG has been 993
for weeks, but every morning there is still a trace ring of bubbles on
the surface of the demijohn. It has been racked once, and appears not
to have a heavy sediment at this point as none is realy visible, but
obviously, this is concord so its a bit dark.

I want to sorbate. My wife wants to drink her plonk, and I need to use
up some bottles...the bubbles worry me enough to hope sorbating will
help insure against exploding vino. I have a house full of little
kids.

My question is this: should I rack before sorbating? If I sorbate as-
is, will the stirring to distribute the sorbate throw the sediment up
so badly that I might have to wait a really long time before I have a
clear wine again?

Thanks

Sean
