Just another note: (I re-read your post)
It's hazy? Hmmmm...
Like, supercloudy hazy, or has it gotten better?
If it has gotten better, you're okay. Just a normal process of clearing.
If it's still as cloudy as it was when you racked it to glass, we've got a larger problem on our hands.
If the latter, I would suggest sparkelloid or even superkleer. The latter of the two is probably a better "all-around" clearing agent. If you started this wine in april/may, and it's somewhat better than when you started, you're being impatient.
It's only 4-5 months old.
Fine Wine Takes Time.
Now, the cloudiness otherwise (if it's as murky as it was when you started, or only slightly better), would mean we have another problem - namely a pectin haze. Now I think this is almost non-existant in lilac wine, but.... not impossible. Superkleer should help you with that as well. As much as it can. Pectin haze is something that you can't really get 100 % rid of. You could try filtering, but it's still not the best.
You might also have to take an SG reading. 0.990? or is it higher? If higher, you might still be fermenting, and don't worry about it if it is. Then we're okay. You've got time! You may be impatient, but you've got time.
As in my previous post, I think this film you're seeing is something of a preservative. I used a bottled-white-grape-juice on my sage, and have something quite similar. I can't figure it out yet what it exactly is, but I have a feeling sulfites are the culprit. (Hence the stirring advice)
You should still try to get the gunk out - and note when you did so, and when you see the film again. If the intervals get longer in between, you'll know it 's just a matter of time. You might want to try a turkey baster or pipette if you don't feel like racking (properly sterilized, mind you!)
Hope this helps,
IT sounds fine, though. Don't worry about it. I tasted my sage, and it was pretty darn good, for being such a green wine!
