                                A glass of sugar-free wine is not calorie-free, with many brands containing at least 30% fewer calories than their sugary counterparts, but not zero. The primary source of calories in these wines comes from the alcohol content, not the minimal residual sugar. Understanding this distinction is key to managing your caloric intake effectively.
