The instructions say my ice wine can be stabiliozed once below 1.060 (and a constant reading). My question is why will there be residual sugar? I assume it because the yeast can't finish it as the alcohol level increases. The residual sugar will be high, giving the ice wine it's very sweet taste? Any chance of the yeast being over achievers and getting down to something much lower than the target? Or underachivers and ending at a higher SG? What if I did a double batch next time (6 gals), would I use both packets of yeast?
