Units by serving size
The classic 3-2-1 recipe uses 3 parts Prosecco, 2 parts Aperol, and 1 part soda water. Because both Aperol and Prosecco sit at 11% ABV in the UK, the alcohol content scales directly with total poured volume:
| Serving size | Prosecco / Aperol | UK units | FR verres (10 g) | US drinks (14 g) | Alcohol grams | Total kcal | % of UK week (14) |
|---|---|---|---|---|---|---|---|
| Small / Bar serve (100 ml) | 60 ml / 40 ml | 1.1 | 0.9 | 0.6 | 8.7 g | ~85 kcal | 7.9% |
| Classic IBA (150 ml) | 90 ml / 60 ml | 1.7 | 1.3 | 0.9 | 13.0 g | ~127 kcal | 11.8% |
| Large Goblet (200 ml) | 120 ml / 80 ml | 2.2 | 1.7 | 1.2 | 17.4 g | ~170 kcal | 15.7% |

Aperol Spritz calories: alcohol vs sugar
Unlike a spirit with a zero-calorie diet mixer, an Aperol Spritz carries calories from two distinct sources:
- Pure ethanol: Alcohol provides 7.1 kcal per gram. In a classic 150 ml Spritz (13.0 g alcohol), ethanol contributes about 92 kcal.
- Residual sugar: Aperol is a liqueur with around 24 g of sugar per 100 ml. Prosecco also carries residual sugar (around 1.2 g per 100 ml for Brut). This adds approximately 35 kcal of carbohydrates.
The total energy is around 125 to 135 kcal per glass, comparable to a 175 ml medium glass of white wine.
Alcohol clearance: how long to process an Aperol Spritz?
The liver metabolises alcohol at a rate of approximately 1 UK unit (8 g of pure ethanol) per hour:
- Absorption window: 20 to 45 minutes after consumption, accelerated slightly by sparkling carbonation.
- Classic serve clearance (1.7 units): Takes approximately 2 to 2.5 hours for complete clearance.
- Two classic Spritzes (3.4 units): Requires roughly 4 to 4.5 hours of liver metabolism.
Health notice: Coffee, sleep and water do not accelerate the action of liver enzymes. These durations are biological guidelines for personal recovery, not legal advice for driving.
Log an Aperol Spritz as 1.7 units, not just one drink.
Common questions
How many units in a standard Aperol Spritz?
A classic Aperol Spritz made to the official IBA recipe (90 ml Prosecco at 11% and 60 ml Aperol at 11% plus a splash of soda) contains 1.7 UK units of pure alcohol (1.65 units unrounded, or about 13.0 g of ethanol).
How many calories in an Aperol Spritz?
Around 125 to 140 kcal for a classic serve. About 92 kcal comes from the pure alcohol, and 35 to 45 kcal comes from residual sugars in the Aperol and Prosecco. Soda water adds zero calories.
What is the alcohol percentage (ABV) of an Aperol Spritz?
Approximately 11% ABV. Both Aperol (11% ABV in the UK and Europe) and standard Prosecco (usually 10.5% to 11.5% ABV) share the same strength, so diluting with ice and a splash of soda water yields a finished drink around 9% to 10% ABV.
Is an Aperol Spritz one standard drink?
In the UK, one Aperol Spritz (1.7 UK units) is more than one 8 g unit. In France, it is 1.3 verres standards (10 g). In the United States, 13 g of alcohol is about 0.93 US standard drinks (14 g).
How much of the weekly guideline is an Aperol Spritz?
One classic Aperol Spritz is about 11.8% of the UK Chief Medical Officers' 14-unit weekly guideline, and 13.0% of the French 10-verre weekly guideline.
How many Aperol Spritzes can you drink in 14 units?
About eight classic Aperol Spritzes (14 ÷ 1.65 = 8.5) spread over three or more days to stay within the UK 14-unit weekly guideline.
