A standard 75cl bottle of prosecco contains about 8 to 9 units of alcohol: 8.3 units at 11% ABV, 8.6 at 11.5% and 9 at 12%. A 125ml flute is about 1.4 units. Champagne is slightly stronger, at around 9 units a bottle and 1.5 units a flute. To work it out for any bottle, multiply the ABV by the volume in millilitres and divide by 1,000.
Prosecco feels lighter than wine, and in one sense it is: most prosecco is bottled at 11% to 11.5% ABV, against 13% to 14% for a typical red. But a bottle is still the same 750ml, so the difference in units is smaller than people expect. Here is the arithmetic, a table for the common pours, and how it compares with champagne, cava and wine.
A UK unit is 10ml of pure alcohol. So:
Units = ABV (%) × volume (ml) ÷ 1,000
For a 75cl bottle at 11%: 11 × 750 ÷ 1,000 = 8.25 units. Check the ABV on the label, because prosecco ranges from 10.5% for some extra dry styles up to 12% for the fuller DOCG wines, and that half-percent either way moves the answer by about 0.4 of a unit.
| Serving | Volume | Units at 11% | Units at 11.5% | Units at 12% |
|---|---|---|---|---|
| Small flute | 125ml | 1.4 | 1.4 | 1.5 |
| Standard pour | 150ml | 1.7 | 1.7 | 1.8 |
| Large wine glass | 175ml | 1.9 | 2.0 | 2.1 |
| Mini bottle | 20cl | 2.2 | 2.3 | 2.4 |
| Half bottle | 37.5cl | 4.1 | 4.3 | 4.5 |
| Standard bottle | 75cl | 8.3 | 8.6 | 9.0 |
| Magnum | 1.5L | 16.5 | 17.3 | 18.0 |
A 75cl bottle pours six 125ml flutes or five 150ml glasses, so if two of you share a bottle over dinner you have each had a little over four units.
| Drink | Typical ABV | Units per 75cl bottle | Units per 125ml glass |
|---|---|---|---|
| Prosecco | 11–12% | 8.3–9.0 | 1.4–1.5 |
| Cava | 11.5–12% | 8.6–9.0 | 1.4–1.5 |
| Champagne | 12–12.5% | 9.0–9.4 | 1.5–1.6 |
| English sparkling wine | 11.5–12.5% | 8.6–9.4 | 1.4–1.6 |
| White wine | 12–13.5% | 9.0–10.1 | 1.5–1.7 |
| Red wine | 13–14.5% | 9.8–10.9 | 1.6–1.8 |
So a bottle of prosecco has roughly one unit less than a bottle of champagne and about two units less than a bottle of red. It is lighter, but not by as much as the taste suggests. For wine in more detail, see how many units are in a bottle of wine.
Alcohol is where most of the calories come from, so lower ABV helps here too. A 125ml flute of brut prosecco is about 80 to 90 calories; a whole bottle is around 500. Extra dry and demi-sec styles carry more residual sugar, which adds a little, and a Bellini or an Aperol spritz adds a lot more than the prosecco in it does.
The Chief Medical Officers' advice is to keep to no more than 14 units a week on a regular basis, spread over three or more days, with some alcohol-free days. A bottle of prosecco is about 8 to 9 of those 14 units, so sharing a bottle over an evening is comfortably inside the guidance; drinking one alone, twice in a week, is not. If you are pregnant, the advice is not to drink at all.
There is no reliable "safe" number of glasses. Units leave the body at roughly one per hour, but that varies with weight, sex, food, sleep and how quickly you drank. A single large glass can take some people over the limit, and the limit in Scotland is lower than in England and Wales. If you are driving, drink something else.
If you want the fizz with fewer units, prosecco at 10.5% or 11% is the lightest of the traditional sparkling wines, and a 20cl bottle is a neat way to have a couple of glasses without opening a full one. Our low and no alcohol range covers the alcohol-free sparkling options.
About 8.3 units at 11% ABV, 8.6 at 11.5% and 9 at 12%. Most prosecco is 11% to 12%, so a 75cl bottle is roughly 8 to 9 units.
A 125ml flute of 11% prosecco is about 1.4 units. A 150ml pour is about 1.7 and a 175ml glass about 1.9.
About 9 to 9.4 units for a 75cl bottle at 12% to 12.5% ABV. A 125ml flute is about 1.5 units, and a magnum around 18.
ABV percentage × volume in ml ÷ 1,000. For a 750ml bottle at 11%: 11 × 750 ÷ 1,000 = 8.25 units.
No, but it is more than half of it. The UK guideline is no more than 14 units a week, spread over three or more days. One bottle is about 8 to 9 units.
The only safe amount before driving is none. One large glass can put some people over the limit, especially in Scotland, and alcohol leaves the body at very different rates from person to person.

Dry, high-acid whites such as Chablis and Sancerre, and brut champagne, are the classic matches for smoked salmon. Here is why they work, what to avoid and how cold to serve them.
