your hydrometer will tell you how much sugar to get the ABV you want, once dry you K-meta it and pectic sorbate, to stop any new fermentation, so you can add sugar your wine to your taste, I and several on here use a triple scale hydrometer, you look at the ABV you want the get the SG reading that matches that, ferment dry add k-meta and potassium sorbate,
