Downsizing wine glasses reduces consumption by 7.6%, study finds

Portion control solution to curb your overall alcohol intake


Key points from article :

Removing the largest wine glass (250ml) from pubs, bars & restaurants reduced wine consumption by 7.6% in a 4-week study.

Customers switched to smaller (125ml & 175ml) glasses, but bottle purchases remained unchanged.

Beer and cider sales, and overall venue revenue, remained steady.

"A 250ml glass of wine costs less than the cost of two 125 ml glasses. Value for money is therefore likely to be influencing a decision," - lead author Dame Theresa Marteau.

Environmental nudges like smaller serving sizes can reduce alcohol consumption subtly.

Pub owners reported positive customer feedback, with some even sticking to smaller glasses after the trial.

Regular heavy drinking is linked to numerous diseases, making this a potentially impactful intervention.
