How many units are in a bottle of prosecco?
8.3units
That is a 750ml bottle at 11% 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.
Prosecco is usually 11% ABV, a little weaker than still wine, so a bottle works out slightly lower than a bottle of red. The glasses are smaller, which makes the total easy to lose track of.

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.
