I have a white zin kit I fermented to dryness (0.998), and want to sweeten
it to a semi-sweet. Is there an SG chart showing approx readings for dry,
semi-dry, semi-sweet, and sweet? I know adding sugar will change the SG,
but besides just tasting it I don't know how much sugar to add to get it to
the semi-sweet neighborhood.

So, is there a chart?
