Iowa State University researchers are trying to help people control alcohol intake.
In a study with Cornell University, researchers found people are more generous in their wine pouring than they realize.
Results show people pour about 12-percent more than a normal serving without realizing it.
People are typically more generous with wider glasses and white wine.
People pour more accurately with red wine and if the glass is on a table as opposed to in their hand.
Researchers say knowing all this can help you control your intake.
