How many units are in a bottle of wine?
9.8units
That is a standard 750ml bottle at 13% ABV. One UK unit is 10ml of pure alcohol. The weekly guideline of 14 units works out at about 1 of these across a whole week.
Most wine sold in the UK is between 12% and 14% ABV, and a standard bottle holds 750ml. That puts a whole bottle close to, or above, the entire weekly guideline for one person.

| Half bottle of 13% | 375ml | 13% | 4.9 |
| 1.5 litre magnum of 13% | 1500ml | 13% | 20 |
One bottle of 13% wine is close to 70% of the entire weekly guideline of 14 units. Splitting a bottle between two people is still around five units each.
How this is worked out
units = volume (ml) × ABV (%) ÷ 1000
For a standard 750ml bottle at 13% ABV: 750 × 13 ÷ 1000 = 9.8 units.

The UK Chief Medical Officers advise no more than 14units a week for men and women alike, spread over three days or more, with several drink-free days. Drinking a week's worth in one session carries its own risks, separate from the weekly total.
If you drink heavily every day, stopping suddenly can be dangerous. Speak to your GP before cutting down sharply.
