You can work out how many units there are in a bottle of wine by using the formula below:įor example, to work out the number of units in a large, 250ml glass of 13% ABV wine:ġ3 (ABV) x 250 (ml) ÷ 1000 = 3.25 units Wine by the bottle unit guideġx bottle (750ml) of 10% Wine = 7.5 Unitsġx bottle (750ml) of 13% Wine = 9.75 Unitsġx bottle (750ml) of 20% Port or Sherry = 15 Units Then, you would multiply 180 by the number of calories in a gram of alcohol, which is 7. To calculate the number of calories in a magnum bottle of red wine with an ABV of 12, you would multiply 0.12 by 1,500, which equals 180. There are also lots of wine varieties, such as Muscadel & Pinot Grigio, that are naturally lighter in alcohol - so keep your eyes peeled for them when you buy your next bottle. So, a standard bottle of red wine with an ABV of 12 would have 630 calories (90 x 7). Fortified wine such as port and sherry is higher still, sitting at around 20%.
