Overview

• Removing the largest wine glass serving size from pubs and bars led to an average decrease in the amount of wine sold of just under 8%, according to a study by the University of Cambridge.
• The study found no evidence that people compensated for drinking less wine by buying more beer or cider.
• Despite the reduction in wine sales, the study found no evidence that the move affected total profits, suggesting pubs and bars did not need to worry about losing money.
• Researchers suggest that even a small reduction in how much alcohol people drink could make a meaningful contribution to the health of the population.
• The study found that 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.
