Summary: The size of a wine glass has increased sevenfold in the past 300 years. The increase in wine consumption is speculated to follow this design shift toward larger wine glass size. This underscores an important and often overlooked factor in UX design: context of use.
Wine consumption has rocketed, and historically keeps increasing with the size of the glass. Researchers suspect wine glass design is increasing consumption.
According to a recent BBC report:
University of Cambridge researchers found glass size grew from an average 66ml in the 1700s to 449ml today - a near sevenfold increase - and wine drinking nearly doubled from 1980-2004.
