If you like the wine dry then leave it alone for a few months with the exception of adding k-meta or(campden tablets)every 2-3 months to protect your wine from oxidising. Without going back and reading this post in entirety, Im guessing that you havent stabilized this wine yet or degassed so do this now by adding 1 campden tablet per gallon well crushed and dissolved in 1 cup of wine that you can extract from your batch along with Potassium sorbate at a ratio of 1/2 tsp per gallon. At this point you can sweeten your wine after you have stabilized it. That can be done by making a simple syrup consisting of 2 cups of sugar dissolved into 1 cup of boiling water, cooled down and then added slowly to taste so as not to over sweeten!
