How UK alcohol units are calculated
Units are calculated by multiplying drink volume in millilitres by ABV and dividing by 1,000. For example, drink size and strength both affect the result.
Understanding calorie estimates
Alcohol provides energy, while sugar, mixers and other ingredients can add more. Cocktail recipes vary particularly widely, so their calorie result is a broad estimate.
