sugar

[knockabout]

Is there a certain amt or percentage of sugar in an off dry semi sweet and sweet wine? Does anyone know what these percentages are or if they change from wine/varietal to wine?
Thanks!

Some more here too! Remembering of course that all mouths are not the same so any rating scale you ascribe to will be a generalization.
