Analysis of more than 30 bottles of wine has found two glasses could be enough to reach the recommended daily sugar limit for adults.
Research by Alcohol Health Alliance UK found some bottles had up to 59g of sugar – more than a glazed doughnut.
An independent laboratory analysed bottles of red, white, rosé, fruit and sparkling wine from popular UK brands.
None of the bottles featured nutritional information on labels as this is currently not required by law.
Calorie content was only displayed on a fifth of the bottles analysed by the lab.
Campaigners are calling for change, to better inform wine drinkers about how many calories and how much sugar they are consuming.
The NHS recommends adults consume a maximum of 30g of “free sugars” per day, which includes sugar in fruit juices and smoothies, or sugar added to food or drink.
Analysis shows that it’s possible to reach an adult’s daily sugar limit by drinking two medium-sized glasses of some wines. -BBC
