Keto alcohol – the best and the worst drinksketo diet? First the obvious: Alcohol is not a weight-loss aid. The more alcohol you drink, the more weight loss may slow down, as the body tends to burn the alcohol before anything else.1 Drinking alcohol can also make people want to eat more.2
With that said, there is a huge difference between different kinds of drinks when it comes to how many carbs they contain – some are pretty ok, some are disasters.
The short version: wine is much lower in carbs than beer, so most people who eat keto choose wine. Pure spirits like whiskey and vodka contain zero carbs, but watch out for sweet drinks – they may contain massive amounts of sugar.
Wine and beer
Even on a keto diet (below 20 grams per day) you can probably have a glass of wine fairly regularly. And on a moderate low-carb diet, wine is not a problem.
Please note that dry wines usually contain less than 0.5 grams of sugar per glass.4 The other substances, often counted as carbs, constitute miscellaneous remains from the fermentation process, like glycerol, that should have a minimal effect on blood sugar or insulin levels.5 Using the number 2 grams of carbs per glass of dry wine is conservative. All dry wines fit well within a keto diet.6
Sweet dessert wines, however, contain a lot more sugar.
Beer is a problem on keto. There’s a reason people talk about “beer bellies”. There are lots of rapidly digestible carbs in beer – it’s been called liquid bread.7 For that reason, unfortunately, most beers are a disaster for weight control and should be avoided on keto.
Note that the amount of carbs in beer vary depending on the brand. There are a few possible low-carb options for keto. Check out our keto beer guide below for details.
The numbers represent grams of carbs per drink, e.g. what you’ll get if you order one in a bar.
When it comes to drinks, it’s pretty straightforward. Pure spirits like whiskey, brandy, cognac, vodka, tequila contain zero carbs and they are all fine on keto.
However, avoid sugar-sweetened drinks. Note that the popular drink Gin & tonic is full of sugar, 14 grams – a common mistake on keto. Switch to vodka, soda water and lime instead, and you’ll have zero carbs.
The worst option of all is to mix alcohol with soda or juice, this will be a sugar bomb.

The numbers represent grams of carbs (sugar) per bottle.
The numbers above are the grams of carbs in one 12 oz. bottle of beer (355 ml).
There are huge differences between different brands, but most contain too many carbs to fit a keto diet. Even on a more liberal low-carb diet it might be wise to keep beer drinking as an occasional thing.
The exception is very light American beers. Many of them contain few carbs, so if you like them you are in luck. Check out the brands to the left in the graphic above.8
Top 5 keto alcoholic drinks
On a keto diet, you can still enjoy a delicious drink or two on special occasions. Even though many alcoholic drinks contain a lot of sugar, there are still some really good keto options, with little or no sugar or other carbs. Here’s our list of the top 5 keto alcoholic drinks.
- Champagne or sparkling wine (extra dry or brut) – one glass contains about 2 grams of net carbs.
- Dry wine – red or white – one glass contains about 2 grams of net carbs.
- “Skinny Bitch” – one long drink contains 0 grams of carbs.
- Whiskey – one drink contains 0 grams of carbs.
- Dry Martini – one cocktail contains 0 grams of carbs.
Pop the bubbly for a low carb toast to good health. Whether it is expensive Champagne from France, or other more affordable sparkling wines like Cava or Prosecco, from other countries, look for the driest versions and enjoy as an aperitif, with food or as a stand-alone drink.
“Beer is made by man, but wine is made by God” said Martin Luther. Some have called it the fourth macronutrient, after fat, protein and carbs. It has been part of human civilization for at least 8,000 years — and no wonder, it pairs so wonderfully with food and friends. Fortunately, dry wine from time-to-time is fine on a keto diet.
The go-to drink of the “Real Housewives of” TV franchise, skinny bitch has the country-club cachet but not the carbs of the old standby gin-and-tonic. Sparkling, light and refreshing, it consists of just vodka, soda water, and lime, perfect to sip and dish the dirt.
“Whiskey is liquid sunshine,” said George Bernard Shaw. Whether you like it neat, with rocks, soda or water, it’s zero carb and gluten free, even though it comes from fermented grains. Scotch, Irish, Canadian, Bourbon, Rye — whatever its name and style, it’s okay for a special occasion.
In the books James Bond liked his martini with 3 parts Gordon’s gin, 1 part vodka, and a half jigger of Kina Lillet. On the screen it was always a vodka martini with a whisper of vermouth, garnished with a lemon twist. It’s a strong drink, even for a secret agent. Whether made with gin or vodka, and garnished with an olive, a lemon twist or a pearl onion, martinis remain one of the most popular aperitifs — shaken, not stirred, of course.
A word of caution
When on a keto diet, most people might need significantly less alcohol to get intoxicated.9 So be careful the first time you drink alcohol on keto. You may only need half as many drinks as usual to enjoy yourself. Keto can save you money at the bar.
The reasons for this common experience are not fully known. Possibly the liver is busy producing ketones or glucose, and thus has less capacity to burn alcohol.
That’s great if you are looking for alcohol’s intoxicating impact — less might get you more and save you money in the bargain. But the hangover could be worse.10
Be very careful for anything in which impairment can increase the risk of accidents or injury. Never drink and drive.
Furthermore, if you’re using a keto diet to treat metabolic syndrome and a fatty liver, be aware that alcohol can have a negative effect, making it harder to reverse a fatty liver.11 Excessive alcohol acts as a liver toxin.
Finally, it appears that alcohol intake might somewhat reduce ketone production even in the absence of sugar or carbs.12

Alcohol contains calories. Despite that, studies show that at least in the short term, drinking alcohol tends to increase the amount of food subsequently eaten:
For example, here are sugar levels in grams per litre (about 8 glasses) in sparkling wine, depending on sweetness ranking:
Brut Nature (no added sugar) 0–3
Extra Brut 0–6
Extra Dry, Extra Sec, Extra seco 12–17
Dry, Sec, Seco 17–32
Demi-sec, Semi-seco 32–50
Doux, Sweet, Dulce 50+ ↩
Drinking regular wine does not seem to provoke any noticeable increase in blood glucose or insulin levels:
“In the United States, however, carbohydrates are taken to be whatever is left once the contents of water, alcohol, fat, protein and minerals in wine are accounted for. In the US, then, tartaric acid, glycerol and other substances that might not immediately be thought of as carbohydrates would be counted as such, and the carbohydrate content declared for a wine in the US could easily be twice the level that would be declared for the same wine in Australia”:

This is commonly reported by people on a keto diet. However, there isn’t much scientific research yet to explain why tolerance seems to be reduced, just theories.
For more on this, read section #5 here:
To our knowledge, there is no good scientific evidence for this. It’s based mostly on anecdotal reports and that it makes biochemical sense [very weak evidence].
