My muscadine wine started at 1.10 sg and is now down to 1.0 sg. I am getting very little action in the airlock but i am still getting some. Should i go ahead and add the sorbate and sulfite and end the fermentation or just keep waiting it out. Also when i rack the wine i will lose some of wine, should i add water to replace the wine are just not worry about not having exactly six gallons. thanks
