I've seen the low-carb wine. My local liquor store has a big sign advertising it. Someone who works there told me how they make it: They first extract all the sugar, then add a little back in.
I'm not racing out to buy it; a glass of wine is typically 2-3g carbs, and by state law, anything over 7g carbs per glass cannot be called ordinary wine. (Mostly this applies to dessert wine.)
Hard liquors like gin, vodka, rum, and tequila have zero carbs. However, your body burns alcohol before anything else, including carbs. The advantage of a ketogenic diet like Atkins is that you burn the few carbs you do eat, then you start burning your body fat; if you drink, you burn the alcohol first, then the carbs, and you may not even get to the fat.
