Red wine
Find out how many units of alcohol and calories are in a glass of red wine
A glass of red wine might have more alcohol and calories in it than you would expect.
A typical-strength medium (175ml) glass of red wine has around 2.3 units of alcohol. So, over a week, drinking more than a bottle and a half of red wine in total would put you above the UK Chief Medical Officers' (CMO) low risk drinking guidelines, of drinking no more than 14 units a week.
Cutting back will lower your risk of serious diseases such as several types of cancer, heart disease, liver disease and stroke and is likely to improve your overall physical and mental health.

Cutting down on drinking can benefit your waistline too. Alcohol contains almost as many calories as pure fat (around seven calories a gram).1
It’s easy to see how much alcohol is in any red wine - just check the label for the Alcohol by Volume (ABV) or ask at the bar.
The ABV tells you what percentage of the red wine is alcohol. The higher the ABV, the more alcohol is in the drink and the stronger it is - for example, a 13% ABV red wine contains 13% pure alcohol.
The amount of alcohol in red wine can vary. But red wine’s typical strength means drinking two large glasses in one session could mean you’re consuming six and a half units of alcohol, so could be classed as ‘binge drinking’ (more than six units of alcohol in a single session for a woman, or eight for a man).2
Research shows that binge drinking over a three-to-six hour period increases your short-term risk of accidents and injuries by two to five times.3

All alcohol - including red wine, whether it´s Cabernet Sauvignon, Malbec, Merlot or another type - is made from natural starch and sugar. There are more than 150 calories in a typical 175ml glass of red wine4 – slightly more than you would find in a bag of ready salted crisps. That means that, over time, drinking too much can lead to weight gain and start to affect how you look.
What’s more, calories from alcohol are 'empty calories', meaning they have no nutritional value, they don’t benefit our bodies in any way.
An easy way to cut your calorie intake from red wine is to choose a non-alcoholic alternative, a lower-strength wine or, if you’re having more than one glass, alternating between red wine and water.

Different types of wine – whether red, white, rosé or sparkling (like prosecco or champagne) – can vary a lot. They are typically around 11-14% ABV, although some can be as high as 14.5% ABV. The only way to be sure is to check the label.
Choosing a lower-strength drink as a replacement to a full-strength one can be a great way to cut out unnecessary alcohol and calories. And there are more, lower-strength wines available than ever before in supermarkets and pubs. A lower-strength red wine could be around 5.5% ABV5 – so would cut your alcohol consumption by more than half compared to a typical equivalent size glass of full-strength red wine.
Even better for reducing your alcohol intake would be a ‘low alcohol’ red wine. These aren’t allowed to be more than 1.2% ABV,6 and many are around 0.5% ABV.
If you’re thinking about cutting the amount of red wine you drink to improve your health or appearance, some great ways to start are:
If you always have a glass of red wine to celebrate a good day at work, or commiserate a bad one, try doing something else instead. An alcohol-free dinner out makes for a feel-good treat, while a gym session is a great way to relieve stress.
There’s always an excuse to have a drink, but it can all start to add up. Taking more drink-free days each week is an easy way to cut back and improve your health. Take our free online Drinking Check to to receive personalised results and guidance.
If you choose to drink, recording exactly what you’ve drunk during the week will tell you whether you're keeping within the unit guidelines. Our free MyDrinkaware app is perfect for tracking your drinks when you’re out and about.
Lower volume (ABV) red wines are becoming much more popular, so try asking for a recommendation or do some research online to find one you like.
Despite some media stories, drinking alcohol increases the risk of heart disease. The health risks of drinking red wine outweigh any possible benefits, even at low levels - read our myth-buster.
After you’ve enjoyed your glass of wine with dinner, you don’t have to drink the rest of it. You could save it, or use it to add flavour to your cooking.
Arming yourself with strategies and tips can help you or a loved one take small steps towards big results.
