Is Alcohol Keto? 8 Drinks Ranked by Net Carbs

Most alcohol can fit a keto diet, but net carbs per serving vary enormously — from 0 g in a straight shot of vodka, tequila, whiskey, or rum to nearly 13 g in a 12 fl oz regular beer. This page is the quick-reference index for the eight most-searched drinks: a sortable table with exact net carbs and a verdict for each, plus links to the full breakdown page for every drink. For the deeper explanation of how alcohol affects ketosis, mixers to avoid, and what to order at a bar, see the full alcohol-on-keto guide.

Which alcoholic drinks are keto-friendly?

Seven of the eight drinks here are keto-friendly, and one — regular beer — is keto-in-moderation only. Pure distilled spirits carry zero carbs because distillation removes all sugar, while wine, champagne, and hard seltzer stay low because little to no residual sugar survives fermentation. Beer is the outlier: it's brewed from grain, and the carbs left behind by that process add up fast.

Drink	Serving	Net carbs	Verdict
Vodka	1.5 fl oz	0 g	✅ Keto-friendly
Tequila	1.5 fl oz	0 g	✅ Keto-friendly
Whiskey	1.5 fl oz	0 g	✅ Keto-friendly
Rum	1.5 fl oz (jigger)	0 g	✅ Keto-friendly
White Claw Hard Seltzer	12 fl oz can	2 g	✅ Keto-friendly
Red Wine	5 fl oz	3.85 g	✅ Keto-friendly
Champagne	5 fl oz	4 g	✅ Keto-friendly
Beer (regular)	12 fl oz	12.64 g	⚠️ Keto-in-moderation

Each linked page has the full total-vs-net carb breakdown, a per-100g figure, and its own FAQ — this hub only summarizes the verdict. The ranking above sorts lowest to highest net carbs per standard serving, which is the fairest way to compare a 1.5 fl oz shot against a 12 fl oz can or a 5 fl oz glass, since serving sizes differ so much across drink types.

Why does net carbs vary so much between these drinks?

Net carbs in alcohol come down to how the drink is made: distilled spirits carry zero because distillation strips out sugar and starch, while fermented drinks like beer, wine, and champagne keep whatever residual sugar survives fermentation. Vodka, tequila, whiskey, and rum all start from a fermented base — grain, agave, or sugarcane — but the distillation step that turns that base into a spirit leaves the carbohydrate behind in the still, not in the bottle. Wine, champagne, and beer skip distillation, so any sugar the yeast didn't fully convert to alcohol stays in the glass. Beer has the most because it's brewed from malted grain rather than fruit, and some of that grain's starch survives the brewing process as unfermentable carbohydrate.

What about cocktails and mixed drinks?

The base spirit in a cocktail can be 0 g net carbs, but mixers usually aren't — juice, soda, tonic, and sweet-and-sour mix can add 10 to 30 g net carbs to a single drink even when the alcohol itself contributes nothing. A vodka soda or tequila with soda water stays close to the spirit's own number, while a margarita, daiquiri, or rum and Coke can rival a dessert in net carbs once the mixer is counted. Because mixer choice matters more than the spirit choice for most cocktails, the alcohol-on-keto guide covers keto-friendly mixer swaps and specific drink-order recommendations in more depth than this index page does.

What alcohol has the least carbs on keto?

Pure distilled spirits have the least carbs on keto — 0 g net carbs per 1.5 fl oz for vodka, tequila, whiskey, and rum. Distillation separates alcohol from the sugars and starches in the original mash or wine, so none of the carbs carry through to the finished spirit. That makes a plain shot, or a spirit mixed with soda water, the lowest-carb order at any bar.

Is beer keto-friendly?

Regular beer is keto-in-moderation, not keto-friendly outright — a 12 fl oz serving has 12.64 g net carbs, by far the highest of these eight drinks. Beer is brewed from malted grain, and the brewing process leaves residual carbohydrate in the finished drink that distillation removes from spirits. One beer can eat a quarter or more of a standard 50 g daily net-carb budget, so it fits best as an occasional choice rather than a daily habit. Light beer styles run lower, generally 2.6 to 5 g net carbs per 12 fl oz — see the full alcohol-on-keto guide for specific light-beer figures.

Can I drink wine on keto?

Yes — a 5 fl oz glass of red wine has 3.85 g net carbs, and dry wines in general stay in the 3 to 4 g range, making wine one of the easier keto-friendly options to enjoy regularly. Stick to dry reds and whites; sweeter dessert wines carry noticeably more residual sugar and more net carbs per glass.

Is champagne OK on keto?

Yes — a 5 fl oz serving of champagne has 4 g net carbs, putting it in the same low range as dry wine. Extra-brut and brut nature styles run even lower, since "brut" designates a drier style with less added sugar (dosage) than sweet sparkling wines. Sweeter styles like demi-sec or doux carry noticeably more sugar per glass, so the label's dryness rating is worth checking before you order.

What is the highest-carb alcohol to avoid on keto?

Sweet dessert wines, cream liqueurs, and sugary mixed cocktails carry the most carbs of any alcohol — often 15 to 30+ g net carbs per serving — well above every drink ranked in the table on this page. None of those made this list because they're rarely a first choice for keto drinkers, but they're worth naming so you know what to skip: port and other dessert wines, coffee and cream liqueurs, sweet vermouth on its own, and any cocktail built on juice, soda, or simple syrup. If you're unsure about a specific bottle or bar order not covered here, the alcohol-on-keto guide has a fuller ranked list, including light beer and common cocktail carb counts.

How do I fit alcohol into my daily carb budget?

Treat any drink's net carbs as part of your daily total, the same as food — a 0 g spirit costs nothing, while a 12.64 g beer can use a quarter of a 50 g budget in one glass. Because alcohol also gets metabolized before fat, drinking can temporarily slow fat-burning and lower the accuracy of ketone readings that night, even when the drink itself has 0 g net carbs. Plan alcohol the same way you plan any higher-carb food: check the number on this table first, then run your day's total through the net-carb calculator to see what's left.

Frequently Asked Questions

What alcohol has the least carbs on keto?

Pure distilled spirits — vodka, tequila, whiskey, and rum — have the least carbs on keto, at 0 g net carbs per 1.5 fl oz. Distillation removes the sugars and starches carried in the original mash or wine.

Is beer keto-friendly?

Regular beer is keto-in-moderation, not fully keto-friendly. A 12 fl oz serving has 12.64 g net carbs, the highest of the eight alcoholic drinks compared here. Light beer runs lower, typically 2.6 to 5 g net carbs per 12 fl oz.

Can I drink wine on keto?

Yes. A 5 fl oz glass of dry red wine has 3.85 g net carbs, and dry wines generally run 3 to 4 g net carbs per serving. Sweeter dessert wines carry more sugar and more net carbs.

Is hard seltzer good for keto?

Yes. A 12 fl oz can of White Claw hard seltzer has 2 g net carbs, making it one of the lower-carb choices here, on par with wine and champagne and well below regular beer.

Does alcohol kick you out of ketosis?

Not directly from carbs if you choose a 0 g spirit, but your body burns alcohol before fat, which can temporarily slow fat-burning and skew ketone readings. Carb content is still the main factor for total daily net carbs, so check the drink's number before you order.
