A standard 750ml bottle of 13% wine contains about 9.75 units of alcohol. The figure changes with strength, so a 14.5% bottle carries nearly 11 units and a 11% bottle around 8.25.
Units matter for licensing conversations, for staff training and for anyone writing responsible-drinking information on a menu or shelf edge. The calculation is straightforward once you know it.
How many units are in a bottle of wine?
Multiply the volume in litres by the ABV percentage. A 0.75-litre bottle at 13% ABV gives 0.75 × 13 = 9.75 units.
That formula works for any container and any strength, which is why it is worth learning rather than memorising a table. A 330ml beer at 5% is 0.33 × 5 = 1.65 units.
How many units by wine strength?
| ABV | Units per 750ml bottle | Units per 175ml glass |
|---|---|---|
| 11% | 8.25 | 1.9 |
| 12% | 9.0 | 2.1 |
| 13% | 9.75 | 2.3 |
| 14% | 10.5 | 2.5 |
| 14.5% | 10.9 | 2.5 |
How many glasses are in a bottle of wine?
A 750ml bottle pours roughly four 175ml glasses, or six 125ml glasses. Most UK venues serve 125ml, 175ml and 250ml measures.
For stock planning, the 175ml pour is the one to cost against: it is the default in most bars, and it means a case of twelve bottles yields about 48 glasses.
How many bottles are in a case of wine?
A standard case holds twelve 750ml bottles, equivalent to nine litres. Six-bottle cases are also common, particularly for premium wine.
When comparing wholesale prices, always confirm whether a quoted case price is for six or twelve — it is the single most common source of confusion in a trade quote.
Why do units matter for licensed premises?
Unit information supports responsible retailing and staff training, and it underpins how you communicate strength to customers. It is also what any conversation with a licensing officer will assume you understand.
The NHS guidance for adults is to drink no more than 14 units a week — a useful benchmark to know when a customer asks what a bottle “counts as”.
