I think I'm zeroing in on my problem, and I'm planning on posting
another message. I've noticed that on these completely fermented
wines, if I take a syringe and just suck back 10 cc of wine and then
re-inject it into the wine, and so this over and over, then I get a
huge amount of bubbling and frothing. In other words, I'm sure that
it's just dissolved CO2, and I guess I'll just drain off a gallon, so
that there's room for bubbling, and then I stir it like crazy until the
bubbling stops.
