Guinness Draught is 4.2% ABV. Guinness’s Irish specification lists 35 kcal per 100 ml, which works out to about 199 kcal in an imperial pint (568 ml) or 166 kcal in a US pint (473 ml). The US product listing gives 125 calories for a 12 fl oz serving. Guinness 0.0 contains 0% alcohol and 17 kcal per 100 ml. The exact number depends on the Guinness variant, country and serving size.
The numbers at a glance
There is no single calorie figure for every Guinness product. Guinness itself says that calories vary by beer and by serving size, such as a pint or can. The table below keeps each figure on the same basis used by the official product information.
| Product and market | Alcohol | Calories and serving basis | Carbohydrate | Fat |
|---|---|---|---|---|
| Guinness Draught, Ireland | 4.2% ABV | 35 kcal per 100 ml; approximately 199 kcal per 568 ml imperial pint | 3 g per 100 ml | 0 g per 100 ml |
| Guinness Draught, United States | 4.2% ABV | 125 calories per 12 fl oz serving | 9.4 g per 12 fl oz serving | Not stated on the cited US listing |
| Guinness Extra Stout/Original | 4.2% ABV | 35 kcal per 100 ml | 3 g per 100 ml | 0 g per 100 ml |
| Guinness 0.0 | 0% ABV | 17 kcal per 100 ml | 3.8 g per 100 ml | 0 g per 100 ml |
The Irish and US Draught entries are not contradictory: one is a density-style figure per 100 ml and the other is a regional serving listing. Their serving volumes and label conventions differ, so quote the basis whenever you quote the calories.

How much alcohol is in Guinness Draught?
Guinness Draught is listed at 4.2% alcohol by volume (ABV) in both the Irish specification and the US product listing. ABV describes the percentage of a drink’s volume that is pure ethanol under the product’s stated conditions; it is not a calorie value and it is not the same as grams of alcohol.

Serving size changes the amount of drink consumed, but it does not change the beer’s stated ABV. A 330 ml serving and a 568 ml imperial pint are both 4.2% ABV if they come from the same Draught product. The larger serving contains more total alcohol because it contains more beer, even though the percentage is unchanged.
Do not convert 4.2% ABV into “units” without naming the country. A UK unit, a US standard drink and other national definitions use different amounts of pure alcohol. The unambiguous figure for Guinness Draught is 4.2% ABV together with the volume you actually pour.
How many calories are in a pint of Guinness?
Imperial pint
An imperial pint is 568 ml. Using the Irish Guinness figure of 35 kcal per 100 ml:
Recommended Free Tools
- 568 ml ÷ 100 ml = 5.68.
- 5.68 × 35 kcal = 198.8 kcal.
- Rounded to a practical label-style number, that is about 199 calories.
This is a calculation from the per-100-ml specification, not a separate 568 ml label declaration. Pouring less than a full pint, leaving foam, or using a different Guinness product changes the result.
US pint
A US pint is 473 ml. Applying the same 35 kcal-per-100-ml figure gives:

- 473 ml ÷ 100 ml = 4.73.
- 4.73 × 35 kcal = 165.55 kcal.
- Rounded, that is about 166 calories.
The calculation illustrates why “a pint of Guinness” needs a volume. An imperial pint is 95 ml larger than a US pint, so the calculated calories differ even when the beer’s per-100-ml composition is identical.
Why the US 12 fl oz figure is different
The US Guinness Draught listing gives 125 calories for 12 US fluid ounces, along with 9.4 g of carbohydrate. Twelve US fluid ounces are approximately 355 ml. That serving is smaller than either a US pint or an imperial pint, and the US figure is published as a serving value rather than as 35 kcal per 100 ml. Use the number printed for the market and serving you are consuming instead of silently transferring a regional value to another package.

For Guinness Draught, the most useful answers are:
- Ireland specification: 35 kcal per 100 ml, 3 g carbohydrate per 100 ml and 0 g fat per 100 ml.
- Calculated imperial pint (568 ml): approximately 199 kcal and approximately 17 g carbohydrate, using the Irish per-100-ml values.
- Calculated US pint (473 ml): approximately 166 kcal and approximately 14.2 g carbohydrate, using the same Irish per-100-ml values.
- US listed serving: 125 calories and 9.4 g carbohydrate per 12 fl oz.
The pint carbohydrate figures are arithmetic estimates from the Irish specification: 3 g × 5.68 equals 17.04 g for an imperial pint, while 3 g × 4.73 equals 14.19 g for a US pint. They should not be presented as a separate package declaration.
How many calories and how much alcohol are in Guinness 0.0?
Guinness 0.0 is listed at 0% ABV and 17 kcal per 100 ml. Its specification also lists 3.8 g carbohydrate and 0 g fat per 100 ml. “0% ABV” is the product’s stated alcohol classification; it is distinct from an alcoholic Guinness at 4.2% ABV or higher.
For volume planning, the 17 kcal-per-100-ml figure calculates to approximately:

Alcohol levels across Guinness variants
Guinness’s FAQ lists the following ABVs. These figures show why identifying the product matters; “Guinness” alone does not identify one alcohol strength.
| Variant | ABV listed by Guinness | Calorie information in the cited specifications |
|---|---|---|
| Guinness Special Export | 8% | Not stated in the cited figures |
| Guinness Foreign Extra Stout | 7.5% | Not stated in the cited figures |
| West Indies Porter | 6% | Not stated in the cited figures |
| Guinness Baltimore Blonde | 5% | Not stated in the cited figures |
| Guinness Smooth | 4.5% | Not stated in the cited figures |
| Guinness Draught | 4.2% | 35 kcal per 100 ml in the Irish specification; 125 calories per 12 fl oz on the US listing |
| Guinness Original/Extra Stout | 4.2% | 35 kcal per 100 ml |
| Guinness Hop House 13 Lager | 4.1% | Not stated in the cited figures |
| Guinness Nitro Cold Brew Coffee | 4% | Not stated in the cited figures |
| Guinness 0.0 | 0% | 17 kcal per 100 ml |
“Not stated” means the cited official information does not provide a comparable calorie number here. It does not mean that the product has no calories. For a particular bottle, can or draught pour, use that product’s local label.
Is Guinness lower in calories than other beer?
There is no reliable yes-or-no answer without naming the competing beers, serving volumes and markets. A fair comparison must put products on the same basis:
- Compare calories per 100 ml, or compare equal serving volumes.
- Match the exact Guinness product: Draught, Original/Extra Stout, a higher-strength export, or 0.0.
- Record the ABV separately; a lower calorie figure does not by itself tell you the alcohol strength.
- Use the same regional definition of a serving. A 12 fl oz US serving is not a pint.
- Read the package for the current market, because the official US and Irish listings use different serving presentations.
The Irish Draught specification of 35 kcal per 100 ml can be compared directly with another beer’s per-100-ml label. A comparison between Guinness’s 125-calorie US serving and another beer’s pint would mix both product and volume differences.

How to calculate calories for the amount you actually drink
When a label gives calories per 100 ml, use this formula:
calories consumed = (millilitres consumed ÷ 100) × calories per 100 ml
For example, a 400 ml glass of a Guinness product labeled at 35 kcal per 100 ml would be 4 × 35 = 140 kcal. If the label gives calories per can or per fluid-ounce serving instead, scale from that declared serving and keep the units consistent.
Do not multiply a US serving number by an imperial-pint conversion unless you have confirmed that the number is intended to apply to the same product and market. Regional formulations, rounding rules and label formats can make that extrapolation misleading.
Common mistakes when quoting Guinness nutrition
Calling every serving “a pint”
State whether the volume is 568 ml (imperial pint), 473 ml (US pint), or 12 US fluid ounces. The word pint alone leaves a 95 ml difference.

Using Draught figures for every Guinness
Special Export, Foreign Extra Stout, West Indies Porter, Smooth and other products have different listed ABVs. Guinness 0.0 is a separate 0% product with its own nutrition panel.
Confusing ABV with alcohol amount
ABV is a concentration by volume. The total alcohol consumed rises with serving volume, even when ABV stays constant. “4.2%” should not be rewritten as a number of grams or national drinking units without additional definitions.
Rounding a calculation as if it were a label
“About 199 calories” is calculated from 35 kcal per 100 ml for 568 ml. It is not evidence that every pour contains exactly 199 calories. Foam level, fill volume and the product selected all matter.
The Tool Desk

Guinness 0.0 has a separately published nutritional profile: 17 kcal and 3.8 g carbohydrate per 100 ml. Use that specification rather than subtracting alcohol-related calories from the Draught figure.
Which figure should you use?
- Counting an Irish imperial pint of Draught: use approximately 199 kcal, based on 35 kcal per 100 ml, and 4.2% ABV.
- Counting a US pint of Draught: approximately 166 kcal when calculated from the Irish per-100-ml specification; check the US package if an exact local label is required.
- Logging a US 12 fl oz Draught serving: use the US listing’s 125 calories and 4.2% ABV.
- Choosing an alcohol-free option: Guinness 0.0 is listed at 0% ABV and 17 kcal per 100 ml.
- Drinking another Guinness variant: identify its full product name and read its local label; the Draught numbers do not automatically transfer.
Bottom line for calorie and alcohol tracking
For the commonly served Guinness Draught, the dependable headline is 4.2% ABV. Calories depend on the label basis: 35 kcal per 100 ml in the Irish specification, about 199 kcal in a 568 ml imperial pint, about 166 kcal in a 473 ml US pint when calculated from that specification, or 125 calories in the US-listed 12 fl oz serving. Guinness 0.0 is listed at 0% ABV and 17 kcal per 100 ml. Always record the variant, market and volume alongside the number.
