How many of you's have tried this. I have a friend who did this and sorbated and sulfited it afterwards and the sweetened at an SG of 1.015 and it refermented on him. Maybe he didnt do it right but I'm not willing to take the chance. I've heard others on a different forum have this problem to and thats why I will not chance it. I'll use the Red Star Cotes Des Blanc and start with a higher SG to accomplish this or just back sweeten. The good Ole tried and true method.
Thats what I did with mine. I recorded an SG of 1.090 for mine to start. I forgot to add the difference for the temperature of the must. After calculations I realize I had a starting SG of 1.102 I used the Red Star Cotes des Blanc yeast so I should be right where I want to be on my batch hopefully.
Bmorosco, don't worry if you were wanting a sweeter wine. You can let it ferment to dry, stabilize and then sweeten without the worry of re-fermentation. Well, I guess I should say there is a chance it could but the chance is much lower.
Letting ferment to dry and sweetening and stopping a fermentation at a specific SG is 2 different things. When you ferment to dry your wine has pretty well used up all of the live and active yeast. The sorbate and sulfite can then kill the few remaining active yeast.
If there is still strong fermentation in process, it is much tougher to accomplish this. You risk re-fermentation or using too much sulfite which can give a foul taste and odor to your wine.
As Wade says, the importance of the yeast used factors this. Each strain has its own work ethic. Some work harder and longer, some not so hard or so long. The Cotes des Blanc yeast will die off and stop fermenting much quicker than the Lavin strain you used. The Lavin is a good yeast for dry reds.
As Wade says, it would be best to ferment to dry, stabilize, degas, and sweeten to taste. You should be fine as this is actually a preferred method for many to start with.
