Low Calorie Alcohol: What It Means and What to Choose

Low calorie alcohol means different things depending on what you are drinking, and the phrase is used loosely enough to be nearly meaningless on a label. There is no legal definition. What there is, is a reasonably simple set of rules about where the calories in a drink come from and which choices genuinely reduce them.

This guide covers what the term actually means for wine, sparkling wine, beer and spirits, gives the figures for every major category, and explains what to look for when nothing useful is printed on the bottle.

Calories by drink, at a glance

Typical servings rather than equal volumes, because nobody drinks a pint of wine.

Where the calories come from

Two sources, and understanding the split explains every figure in that table.

Alcohol carries around 7 calories per gram. That is close to pure fat at 9, and considerably more than carbohydrate or protein at 4. In most drinks, alcohol is the single biggest contributor, which is why strength matters more than almost anything else.

Residual sugar and carbohydrate carry around 4 calories per gram. In wine this is grape sugar left after fermentation. In beer it is grain sugar. In a mixer or a cocktail it is added sugar, and that is usually where the damage is done.

Two practical rules follow. A stronger drink is almost always a higher calorie drink at the same volume. And a sweeter version of any drink will beat a drier one, at the same strength, every time.

There is a fuller breakdown of how the two interact in our comparison of wine and beer calories.

Low calorie wine

A standard 175ml glass of supermarket wine averages 130 to 160 calories. Our wines start from 69 calories per 125ml glass, all at full strength and all with 0g of sugar.

The reduction comes from dry winemaking rather than dilution. Fermenting fully dry converts the grape sugar into alcohol, which removes the sugar calories and leaves the wine at normal strength with its body intact. Nothing is watered down and nothing artificial is added.

What to look for: 0g of residual sugar per serving, an ABV around 11 to 12% rather than 13.5 to 14%, and a published calorie figure per serving rather than an estimate. Our guide to which wines have the lowest sugar content covers the styles, and calories in a bottle of red wine goes deeper on reds specifically.

Low calorie sparkling wine

Sparkling wine is already lower in calories than still wine at the same pour, partly because it tends to be weaker and partly because the standard glass is 125ml rather than 175ml. A Brut Prosecco averages 80 to 90 calories a glass against 95 to 110 for a still white.

Sparkling has one advantage no other category offers: the sweetness is printed on every bottle. Brut Nature is the driest, then Extra Brut, then Brut. Anything labelled Extra Dry or Demi-Sec is sweeter, despite the names.

The TRACES Prosecco DOC Treviso sits at 78 calories per 125ml with 0g sugar at 11% ABV. There is more detail in our guides to calories in Prosecco and how much sugar is in Prosecco.

Low calorie beer

Standard lager averages 220 to 250 calories a pint and around 140 per 330ml bottle. Low calorie beers use extended fermentation to convert more of the grain sugar into alcohol, which leaves fewer carbohydrates in the finished beer without dropping the strength.

Tennent's Light comes in at 60 calories and 0.7g of carbohydrate per 330ml bottle at 3.5% ABV, which is the lowest we stock. The rest of the range runs up to about 99 calories a bottle.

Our guide to calories in beer compares the mainstream brands, and calories in a pint of lager covers the pint specifically.

Spirits and mixers

Neat spirits are the lowest calorie option available. A 25ml measure of gin, vodka, whisky or rum carries around 55 calories and no carbohydrate at all, because distillation leaves nothing but alcohol and water behind.

The mixer is where it goes wrong. A standard 200ml tonic contains roughly 15g of sugar, which more than doubles the calorie count of the drink and turns a zero carb spirit into something sweeter than most wine. Cola, lemonade and fruit juice are worse.

Soda water, slimline tonic, sparkling water and fresh lime all solve it at no cost to the drink. Pre-mixed cans are the ones to watch, since many carry 180 to 220 calories and 20 to 35g of carbohydrate, printed in small type on the back.

What to avoid

Cider. Around 230 calories a pint and 15 to 20g of carbohydrate per 330ml, and fruit varieties are higher still. See how much sugar is in cider.

Sweet and dessert wines. Sauternes, Moscato, Port and Tokaji all carry substantial residual sugar by design.

Liqueurs. Baileys, Kahlúa and similar are sweetened as a matter of course.

Cocktails. The spirit is rarely the problem. Syrups, juices and mixers are.

Alcohol-free alternatives, sometimes. Counterintuitively, many contain more sugar than the drink they replace, because producers add it to compensate for the body lost with the alcohol. Our look at whether non-alcoholic beer is lower in calories covers this.

Low calorie, low alcohol and alcohol-free are three different things

They get used interchangeably and they are not the same.

Low calorie keeps the strength and reduces the sugar or carbohydrate, usually through how the drink is made. Same drink, fewer calories.

Low alcohol reduces the ABV, typically to between 0.5% and 1.2%. Fewer calories as a consequence, but a noticeably different drink.

Alcohol-free removes the alcohol almost entirely, at 0.05% or below, and frequently adds sugar to replace the lost body.

If you want the drink you already enjoy with fewer calories, the first is what you are after. If you want to reduce your alcohol intake, the other two are the relevant ones.

How to check before you buy

UK labelling rules do not require nutritional information on drinks above 1.2% ABV, unlike food and soft drinks, so most bottles tell you nothing at all. Four things that work:

Check the ABV. It is legally required, it is on every bottle, and it is the single biggest driver of the calorie count.

Check the sweetness classification if it is sparkling wine. Brut Nature and Extra Brut are the driest.

Look for a published figure per serving. Retailers who publish calorie and sugar content are giving you something they are not obliged to provide.

Watch the pour. A 250ml glass of wine carries twice the calories of a 125ml glass. This is the easiest change to make and the one most people overlook.

For guidance on units and drinking sensibly, the NHS and Drinkaware both publish detailed breakdowns.

Frequently asked questions

What is the lowest calorie alcoholic drink?

A neat spirit with soda water, at around 55 calories per 25ml measure. Among drinks with more flavour, a dry wine at 69 to 90 calories per 125ml or a low calorie beer at 60 to 99 per bottle.

What alcohol has the least sugar?

Neat spirits contain none at all. Fully dry wine contains 0g per serving. Brut Nature sparkling is next. Cider, sweet wine, liqueurs and pre-mixed cans are the highest.

Is wine or beer lower in calories?

Per serving, wine, because the pour is smaller. Per millilitre, beer, because it is weaker. It depends entirely on how much you have.

Does low calorie alcohol taste different?

It depends how the reduction was achieved. Drinks made lighter through dry winemaking or extended fermentation taste like the original, because nothing has been removed after the fact. Drinks made lighter by dilution taste thinner.

Is low calorie alcohol the same as low alcohol?

No. Low calorie keeps the strength and reduces the sugar. Low alcohol reduces the strength itself.

Why are calories not printed on alcohol labels?

UK rules do not currently require nutritional information on drinks above 1.2% ABV. Most producers publish nothing, which is why the figures are so hard to find.
