Lightly sparkling and sweet, its fermentation is stopped early to keep the sugar — which leaves it among the lowest-alcohol wines made.

UK alcohol units in a medium (175 ml) glass and in a full 750 ml bottle, plus US standard drinks per bottle, for common wine styles. Every figure updates from the same math the calculator uses.
| Wine style | ABV | Units/glass | Units/bottle | Drinks/bottle |
|---|---|---|---|---|

| Vinho Verde | 10% | 1.8 | 7.5 | 4.2 |
| Lambrusco | 10.5% | 1.8 | 7.9 | 4.4 |
| Prosecco | 11% | 1.9 | 8.3 | 4.6 |
| Champagne (Brut) | 12% | 2.1 | 9 | 5.1 |

UK units per glass use a medium 175 ml pour. US standard drinks use the NIAAA 14-gram definition, so a bottle holds fewer standard drinks than UK units for the same wine.
A standard 750 ml bottle, divided by each UK standard glass pour. This count is fixed by the pour size — the wine's strength changes the units, not the number of glasses.

UK alcohol units come straight from the pour — the volume in millilitres times the wine's ABV, divided by 1000 (one unit is 10 ml of pure alcohol). US standard drinks come from the alcohol's mass: the volume, times the ABV, times the density of alcohol, divided by the 14-gram US standard-drink unit. Each wine style uses a widely-published typical ABV, so an individual bottle varies with its exact strength.
The UK's low-risk guideline is not to regularly drink more than 14 units a week — roughly one and a half bottles of a typical 13.5% wine, ideally spread over several days. This is general information, not medical advice.
A standard 750 ml bottle of wine at 13.5% ABV is about 10 units — because UK units are volume times ABV divided by 1000, and 750 × 13.5 ÷ 1000 ≈ 10.1. A lighter 11% wine is closer to 8 units a bottle, while a big 14.5% red is around 11. Pick your wine style above and choose the full-bottle serving to see the exact figure.
It depends on the glass and the wine's strength. A small 125 ml glass of 12% wine is about 1.5 units, a medium 175 ml glass is around 2.1 units, and a large 250 ml glass is roughly 3 units. Stronger wine packs more into the same pour — a 175 ml glass of 14% red is about 2.5 units. Choose your pour above for the exact number.
In the US a standard drink is 14 grams of pure alcohol, so a 750 ml bottle of 12% wine is about 5 standard drinks and a 13.5% bottle is closer to 5.7. Standard drinks are measured by alcohol, so a higher-ABV wine holds more in the same bottle. This is a different measure from UK units (which use 10 ml of alcohol per unit) — the calculator shows both.
A standard 750 ml bottle holds about six small (125 ml) glasses, roughly four to five medium (175 ml) glasses, or three large (250 ml) glasses. The count is fixed by the pour size, not the wine — but a larger pour of a stronger wine still means more units and more standard drinks.
The UK's low-risk guideline is not to regularly drink more than 14 units a week. Because a 13.5% bottle is about 10 units, 14 units works out to roughly one and a half bottles of wine spread across the week — the guideline advises spreading it over three or more days rather than saving it up. This is general information, not medical advice.

SOURCES & FRESHNESS
Unit and standard-drink definitions and the weekly guideline follow UK NHS (alcohol units & the 14-unit weekly guideline) and US NIAAA (standard drink) · verified 2026-09-25. Per-style ABVs are typical published values; the units, standard drinks, and glasses-per-bottle counts are computed by Saignée from those figures.
