The study, published in the journal PLOS Medicine, involved 21 licensed establishments in the UK who agreed to remove the largest serving of wine (typically 250ml) from their menus for four weeks. The researchers then tracked the total volume of wine, beer and cider sold by each business.
The research found that the move away from largest servings of wine has led to a shift towards smaller portion sizes, with sales of 125ml and 175ml glasses of wine increasing. However, this had no impact on sales of bottled wine, beer and cider.
The researchers also found that daily income remained unchanged despite the decline in the volume of wine sold. This shows that the increase in sales of small glasses of wine offset the decrease in sales of large glasses.
The study’s findings have important implications for public health efforts to reduce alcohol consumption. By making it difficult to consume excessive amounts of alcohol, avoiding the largest serving size per glass of wine can help promote healthy drinking habits and reduce the risk of harm from alcohol.
