Wine drinkers could be pouring themselves more than they think, according to a new study by Iowa State University.
Those asked to serve themselves a normal glass of white wine into a clear glass dished out 9% more than when pouring red wine, researchers warned. What’s more, wide glasses received around 12% more than standard receptacles. And topping up your tipple in-hand adds yet another 12% compared to using a table or countertop.
The reason, explains Iowa State’s Laura Smarandescu, is that these variables affect how we assess volumes. So it seems the best way to ensure a clear head is by enjoying a narrow glass of red poured at the dinner table.
