The researchers carried out a crossover trial that includes 217 UK households that drink wine frequently. They have been randomly given 290ml or 350ml glasses to drink from throughout the four-week research interval. Researchers famous that wine consumption fell by 6.5% when these featured within the research have been ingesting from the smaller glasses.
The trial additionally targeted on bottle sizes. The households collaborating within the survey spent two weeks ingesting from full-sized 75cl bottles and two weeks ingesting from half bottles (37.5cl).
Wine consumption fell by 3.6% when half bottles have been used versus 75cl bottles. The researchers mentioned that decline was negligible.
‘Utilizing 290ml vs. 350ml glasses could cut back consumption,’ concluded the research, which was revealed within the Dependancy journal. ‘It’s unclear whether or not utilizing 37.5cl vs. 75cl bottles reduces consumption.’ It added that ‘neither of those results have been statistically important’.
The researchers mentioned that the findings are in step with present proof on the influence of glass sizes within the hospitality sector.
A latest research, additionally revealed in Dependancy, discovered that wine served in bigger glasses elevated the quantity consumed in eating places, however not in bars.
Nonetheless, the researchers admitted that their research had a number of limitations. It didn’t think about consumption of different alcoholic drinks, and the information was additionally primarily collected when bars and eating places have been closed throughout the Covid-19 lockdown lockdown.
They mentioned additional analysis will probably be required to attract any agency conclusions. ‘If the consequences of wine glass measurement on consumption are proved dependable with results sustained over time, decreasing the dimensions of wine glasses utilized in properties might contribute to insurance policies for decreasing alcohol consumption,’ mentioned the researchers.
They instructed ‘pricing glasses based on capability’, which might improve demand for smaller glasses, and probably regulating glass measurement and serving measurement in eating places and bars.
