Guideline daily amounts suggest that women should consume no more than 90g and men no more than 120g of sugar each day. When avoiding or limiting sugar for dental, general health or weight loss, or to control diabetes, enjoying an alcoholic drink isn't a problem. There are many sugar-free and low-sugar alcoholic drinks to choose from.
Beers and lagers such as Budweiser, Corona and similar contain little to no sugar, since the sugar has been converted by yeast into alcohol; this makies beer an ideal sugar-free alcoholic drink. Bear in mind that sugar-free does not mean calorie-free, so beers still count toward the daily calorific intake of 2,000 for women and 2,500 for men.
Liquors and Spirits
On their own, spirits and liquors such as gin, rum, vodka and whiskey contain no sugar. Again, this does not mean that they are calorie-free (a shot of vodka has 55 calories) so bear this in mind if you're trying to lose weight.
One of the biggest sources of sugar when drinking alcohol is actually the mixers with which it's mixed and served. One can of non-diet drink such as cola contains at least 40g of sugar, so be sure to avoid cola- and lemonade-style mixers in favour of sugar-free "diet" varieties.
Fruit juices used as mixers or in cocktails are always naturally high in sugar. Although the sugar in fruit is not considered unhealthy because of the high amount of fibre that comes with it, this isn't true of juiced fruit. Juices like orange and cranberry in alcoholic drinks should be avoided by people looking for sugar-free alcoholic drinks.
Wine, being made predominantly from grapes, does contain a small amount of sugar, so it is not strictly a sugar-free alcoholic drink. However, the amount of sugar it contains is very low at around 0.22g per 100ml for white wine and 0.62g per 110ml for red wine.
