Wine colour and glass shape determines how much you drink





A team of researchers from Iowa State and Cornell Universities have found that the shape of one’s wine glass and colour of wine can have an unintentional effect on how much you drink.

Their study, in response to similar environmental research into how plate size and food labels can impact on eating patterns, concluded that drinkers poured larger servings when the wine was white and when the wine glass was wider.

The experiment focused on 73 wine drinkers and revealed that 11.9% more wine was consumed when using wider glasses, while the results also suggested the students poured 12.2 per cent more when they were holding their glasses, compared with pouring into glasses placed on a table.

The participants poured 9.2% more white wine than red, with researchers suggesting the deep contrast between red wine and the colour of glass.

Dr Doug Walker, lead author of the study, said: "If you ask someone how much they drink and they report it in a number of servings, for a self-pour that's just not telling the whole story.

"One person's two is totally different than another person's two. Participants in the study were asked to pour the same amount at each setting, but they just couldn't tell the difference."

The study, also co-authored by Laura Smarandescu and Brian Wansink, reads: “Now you know that you’re likely to overpour if you choose a wide glass, hold your glass while serving, or select a wine that matches your glass.

"But the good news is that, retrospectively, people seem to be aware of how these cues influence their pours.”

It concluded: “Being aware of the wine cues that impact pouring can help drinkers monitor their intake.

"However, knowing that you’ll pour more into a wide glass is different than knowing just how many ounces you’ll pour. When trying to monitor your alcohol consumption accurately, realise that you may be serving yourself 12 per cent more alcohol than you originally planned.

"When given the option, choose a narrower glass, place your glass on a table before pouring, and select a wine that does not match your glass to avoid unintentionally over-serving.”
