the sale of wine in glasses largest wine may encourage people to drink more, even when the amount of wine remains the same, suggests new research from the University Cambridge. In a study published today in the journal BMC Public Health , researchers found that increasing the size of the glasses of wine resulted in an increase of almost 10% in wine sales.

Alcohol is one of the main risk factors for the disease and has been linked to diseases such as type 2 diabetes, cancer and liver disease. Factors influencing consumption are not clear; A recent Cochrane review published by the Unit of Behavior and Health Research (bhrū) at the University of Cambridge found that larger and crockery increased consumption of food and non-alcoholic beverages, but found no evidence related to alcohol servings.

To examine whether the crystal size in which alcohol is served affect consumption, equipment bhrū, along with Professor Marcus Munafo of Bristol University, conducted a study in La Pinta Shop in Cambridge from mid-March to early July 2015. The hotel has separate bar and restaurant areas, selling both food and drink. Wine (125 ml portions or 175 ml) could be bought by the glass, which was usually a standard size of 300 ml.

Over a period of 16 weeks establishment owners changed the size of the glasses of wine at two-week intervals, alternating between the standard (300 ml) size and larger (370ml) and glasses smaller (250 ml).

The researchers found that the volume of purchased wine daily was 9.4% higher when sold in larger vessels compared to standard-size vessels. This effect was mainly driven by sales in the bar area, which recorded an increase in sales of 14.4%, compared with an increase of 8.2% in sales in the restaurant. The results were inconclusive as to whether sales were different with smaller vessels compared to standard size.

“We found that increasing the size of wine glasses, even without increasing the amount of wine, leads people to drink more,” says Dr. Rachel Pechey of bhrū in Cambridge. “It is not obvious why this should be the case, but one reason may be that larger glasses change our perception of the amount of wine, which leads us to drink faster and to order more. But it is interesting that we have not seen the opposite effect when we switched to smaller wine glasses. ”

Professor Theresa Marteau, Director of the Unit, adds. “This suggests that avoiding the use of glasses of wine larger could reduce the amount you drink people need more research to confirm this effect, but if necessary , then we have to think about how this could be implemented. for example, could be a requirement alcohol license all wineglasses must be below a certain size? “
