Distilled alcohol has no carbs -- all of it. Whiskey, rum, vodka, gin, etc. The carbs are in the mixer if it isn't sugar free. Wine and beer have various carb counts, beer, I believe, having the most.
We learned this researching when hubby was diagnosed with diabetes. When he has wine or beer he has to count it as one of his starches at dinner or snack.
As already said, if you're talking about weight control, they're all empty calories.
Go buy a good food guide -- there are many out there to help you that will have calorie, fat, carb, protien, etc counts.
