I have heard of people using saccharin to sweeten wine but
I think that most people here would not use it for that.
Instead they would use sugar or grape juice and potassium
sorbate since the sorbate has less of a noticeable affect
and the saccharin has a definite taste. Can't help you with
the quantities.
