The volume of wine that bar and pub customers drink in one session is reduced if the largest serving by the glass is removed, a study suggests. Researchers say the discovery could nudge people to drink less alcohol, after finding people tend to consume the same number of glasses, regardless of the glass size.
It looks like when the largest serving size of wine by the glass was unavailable, people shifted towards the smaller options, but didn't then drink the equivalent amount of wine. People tend to consume a specific number of units in this case glasses regardless of portion size. So someone might decide at the outset they'll limit themselves to a couple of glasses of wine, and with less alcohol in each glass they drink less overall.
The number of women dying from alcohol-related diseases has soared in recent years. Even when taking into account the day of the week and total revenue, the scientists found that removing the largest wine glass serving usually 250ml led to a drop in wine on average sold each day of around 420ml at any given pub or wine bar a 7.6 per cent decrease. They also found no evidence that people were making up for drinking less wine by buying more beer or cider.
Alcohol consumption is the fifth-largest contributor to premature death and disease worldwide. According to the World Health Organisation, the harmful use of alcohol led to around three million deaths worldwide in 2016.
