Whats the difference

[Innkeeper]

Squtte has the right idea. A dry wine is one in which all the sugar in a wine has been converted to alcohol. The less sugar to begin with, usually the less ripe the grapes, the less alcohol you end up with. If all the sugar is not converted, or if plain juice with sugar is added after fermentation, you have an off dry wine. The degree of sweetness is measured in % of residual sugar (RS). Sometimes, when it is not on the bottle, it is difficult to determine how much residual sugar is in a wine. Experimentation is the best teacher. Bear in mind that the overwhelming majority of table wine is dry. Let's say 90% to at least gain perspective.

The taste is up to you. Healthwise, wine without residual sugar has fewer calories, and fewer carbohydrates.
