Low-Carb Drinks at a Bar: What to Order, With Live Data

By the DrinkLeader team · Published 2026-10-14 · Data updated 2026-10-12 · 8 min read

The lowest-carb order at a bar is a spirit with soda water and a lime: vodka, gin, tequila, whiskey and rum all list 0g to 0.6g of carbs per pour on average in the catalog. After that come light beer, dry wine and hard seltzer. Sweet cocktails such as a margarita, which lists up to 32g in the catalog, are where the carbs are.

Step one: choose the base

The base spirit does almost nothing to your carb count. Distilled spirits keep virtually none of the sugar through distillation, so a plain pour of vodka, gin, tequila, whiskey, bourbon or rum lists 0g or close to it, with calories coming from the alcohol. The NIAAA standard drink for spirits is 1.5 fl oz at about 40% ABV, which holds 14 grams of alcohol, and lists about 100 calories. Here is how the averages line up:

Liqueurs are the exception among spirits: they are sweetened, and only 18% of them list 5g or less. If a bartender is reaching for a bottle with a cordial or schnapps label, treat it like a sugar source. The carbs in alcohol guide covers the full type-by-type picture.

Step two: choose the mixer

This is where the order gets decided. Soda water and a squeeze of lime add essentially nothing. Diet cola and diet tonic are close to nothing. Juice, regular soda, sweet-and-sour mix and syrup add the grams. The low-sugar mixers guide and the sugar-free mixers guide cover that choice. Among the bar-style cocktails in the catalog, these list the fewest carbs:

Spirit-forward classics, diet-mixer highballs and martinis dominate the top of the table. Note that a martini is low in carbs but high in alcohol: look at the ABV and the serving size, because a 3.5 oz martini can hold more alcohol than a 12 oz beer. The first three rows (the blended strawberry daiquiri, the Cape Cod and the Irish Car Bomb) list 0g of carbs, which looks understated for drinks that normally contain juice, sugar or beer, so do not rely on them. The diet-mixer highballs and martinis are the dependable low-carb rows.

Drinks to skip, or order with changes

These are the highest-carb cocktails in the catalog, which is where "I'll just have a margarita" gets expensive:

Sweet-and-sour mix, liqueurs and juice make up the carbs. If you want a lighter version, ask for the same spirit with soda water and fresh citrus, which is the model the low-calorie cocktails guide uses.

Beer at a bar

If you would rather drink beer, light and ultra-low-carb styles are the choice. These list the fewest carbs in the catalog:

These are lighter, lower-ABV styles. Popular imports such as Modelo and Michelob Ultra have their own pages, and the low-carb beer guide ranks more. Only 54 of 869 beers list 5g or less, so most beer on tap is not a low-carb order.

Wine at a bar

Dry wine and brut sparkling are low in carbs per 5 oz glass:

Dessert wines and sweet styles sit at the other end. If the menu does not say, ask for a dry white, a dry red or a brut sparkling. The low-carb wine guide goes deeper, and the average catalog wine is 4.6g per glass.

A quick bar-order cheat sheet

• Easiest: vodka, gin, tequila, whiskey or rum with soda water and lime.
• Also fine: the same spirits neat or on the rocks.
• Mixer swaps: diet cola, diet tonic, or soda with a splash of juice at most.
• Beer: a light or ultra-low-carb lager.
• Wine: dry white, dry red or brut sparkling.
• Seltzer: a clear seltzer or ranch water; the hard seltzer guide lists the lowest.
• Skip: mixes, syrups, liqueurs, cream and juice-heavy drinks.

For lists you can browse, see the zero-carb drinks and under 2g of carbs pages, or the keto alcohol guide. Remember that low carbs are not low alcohol: a double pour of spirits is two standard drinks, and the calories add up regardless of the mixer.

How to read the numbers

Bar-style cocktails are estimated from standard recipes, rescaled to the serving shown, while canned and bottled products use producer figures where they exist. The recipe at a particular bar will differ, and the pour sizes vary. A listed 0g is an indication, not a promise. The methodology page has the details.
