Just my 2 cents - Ocean Spray cranberry juice has sorbate or similar in
it. When I added juice like that to a wine, it stabilized it without
needing sorbate.

Just fyi, I am only 3 years into making wines, so I'm not an expert. But
I also like to make some juice/wine blends for friends and family (In
NC, they like it sweet. Not me!)
