Scary truth about your favourite wines: Diet experts rank brands by sugar content – shockingly, one has almost as much as a can of Coke

Treating yourself to a glass of wine or two after a hard day? You could be consuming dangerous quantities of hidden sugars, experts warn.

They said some popular tipples found on supermarket shelves are essentially a ‘dessert in a bottle’ and can contain almost as much sugar as a can of Coke.  

The £8 sparkling Californian rosé Barefoot Bubbly Pink Moscato topped the charts for sugar content at nearly 14g per 175ml glass, equivalent to three teaspoons of sugar.

This is just a few grams of sugar shy of the equivalent amount of Original Coca-Cola, which contains about 18.5g of sugar per 175ml.

The NHS warns people to limit their daily intake of free sugars, those added to food or drinks, to just 30g per day.

This means even one standard glass of Barefoot Bubbly Pink Moscato accounts for nearly half of an adult’s daily sugar limit. 

Barefoot’s non-sparkling rosé came second for sugary wines at 11g per 175ml followed by Echo Falls Fruit Fusion Summer Berries at 9.2g.      

Jonny Inglis, founder of wine club Winedrops.com, said many wine drinkers are unaware of just how much sugar was hidden inside their favourite bottles. 

‘Many people focus on cutting back on biscuits or soft drinks, but don’t realise their evening wine is also a big sugar source,’ he said. 

‘Some wines pack in more sugar per glass than fruit juice, and a few even edge close to fizzy drinks.’

‘Since wine bottles don’t come with clear sugar labels, most consumers are completely unaware of what they’re drinking.’

A single 150ml serving of orange or apple juice contains roughly between 12g and 15g of sugar. 

Mr Inglis said rosé enjoyers need to be particularly aware of sugar content as it can vary significantly between brands.

But he added those who opt for white or red also need to be cautious. 

Champagne Doux, a sweeter version of the fizzy favourite contained 7.5g per glass, equivalent to about one and half teaspoons. 

For reds 19 Crimes Red Blend took the top spot at 7g of sugar per 175ml serving. 

Mr Inglis said wine drinkers who wanted to cut back on their sugar intake should lean towards a dry white or red which contain between zero to 2g of sugar per glass. 

‘Dry wines are fermented longer, meaning more of the natural grape sugars are converted into alcohol,’ he said. 

‘This is why a bottle of dry red or white will have significantly less sugar than something like a fruit wine or a semi-sweet rosé.’

Rob Hobson, registered nutritionist, told MailOnline that wine drinkers should keep an eye on how much sugar the beverage was adding to their diet. 

‘Most people do not link the wine they are drinking with their sugar intake,’ he said. 

‘In dry wines, the sugar content is minimal (often 1-3g per glass) and is not typically classified as free sugar because it occurs naturally during fermentation.’ 

However, he said the alcohol content in wines was something people needed to be aware of regardless of the beverage’s sugar content. 

‘Ultimately, cutting back on alcohol consumption is far more important for health than fixating on sugar content,’ he said. 

‘If you do drink wine, choosing drier varieties over sweet wines will help keep sugar intake lower, but reducing overall alcohol intake is the best approach.’

 So-called ‘hidden’ or ‘added’ sugars in modern diets have been blamed for contributing to several health issues.

Some experts consider them to be one of the key driving factors in the rise of obesity and diabetes rates in both Britain and America.

The NHS advises that consuming too much sugar can lead to weight problems like obesity which in turn increase the risk of serious health problems like heart disease, some cancers and type 2 diabetes.

British health officials also recommend people drink no more than 14 units of alcohol per week — the equivalent to six pints of beer, or six medium glasses of wine — spread out over at least three days.

However, up the one in four adults in England report drinking over this level.
