Yet another piece of research on wine drinking? I see most of the readers’ eyes rolling already… Well, this one is rather different, and it may address somehow the lack of consistency of some other research results. Indeed, it is quite usual for drinking research to ask the respondent how many ‘servings’ of alcohol he or she has on a regular basis, being a day, a week, or a month. But as much as science or government can specifically define what is one serving or dose of alcohol, it is not so easy to be that precise or consistent in your pouring, especially with a shaky hand and a dizzy mind.
Researchers at Iowa State University have just put their finger, and an actual number, on this issue. It’s about 10% to give a rough idea. The colour of the wine, the shape of the glass, whether you are pouring holding the glass or not, influence the actual quantity that goes in the glass for about 10%.
Do you think you pour yourself a little more white wine than red wine? Yes you do. About 9% more when it is white wine. Do you think you serve yourself more in bigger / wider glasses? Yes you do too. About 12% more. And finally, is there an effect if you hold the glass when serving instead of delicately throwing the liquid on a glass that stands by itself on the table? Yes, there is, as well. If you hold the glass, you’re going to have about 12% more drink in it.
Although they do not explicitly tell you what happens if you pour white wine in a wide glass that you’re holding, these findings published in the Substance Use & Misuse Journal could have some interesting implications either for on-trade business, or just provide useful information on consumption habits at personal or regulatory level.
