Abstract

What environmental factors bias how much wine a person pours into their glass? Building on research involving visual illusions and haptic cues, an exploratory field study shows that while participating wine drinkers typically poured 3.95 oz. of wine into a standard baseline (10-oz) glass, they poured 11.9% when the glass was wider (such as intended for red wine), 9.2% more when the wine was white (low contrast), and 12.2% more when the wine glass was on the table rather than held in one’s hand. Increasing awareness of pouring biases is a step toward limiting alcohol intake for improved health outcomes and preventing alcohol related problems.

Keywords: Self-serving, glass shape, environmental cues, overconsuming, wine, alcohol
