Does alcohol free wine contain as much sugar (or more) than that which contains alcohol?
It depends on whether it’s a sweet wine, dry wine or red wine. Also it differs from one wine to another. However, if your question relates to calorific content, then the fact that there is no alcohol makes the calorific content of the wine significantly lower. Alcohol has 8 cals/gramme whereas sugar is 4 cals/gramme. So merely by removing the alcohol the calorie content of the wine is significantly reduced.
