The size of glass used for serving wine can influence the amount of wine drunk, say researchers, adding that when restaurants served wine in 370ml rather than 300ml glasses they sold more wine, and tended to sell less when they used 250ml glasses.
The preliminary study, published in the journal Addiction, suggested that serving wine in larger wine glasses — while keeping the same measure — led to a significant increase in the amount of wine sold.
“Pouring wine from a bottle or a carafe, as happens for most wine sold in restaurants, allows people to pour more than a standard serving size, and this effect may increase with the size of the glass and the bottle,” said study first author Mark Pilling from University of Cambridge in the UK.
