UK saw 7-fold increase in wine glass size in 300 yrs: Study
A Cambridge study analysing 411 wine glasses from 1700 to present day has found their capacity gradually increased from 66 ml to nearly 450 ml over 300 years. While a 'Glass Excise' tax in the mid-18th century led to manufacturing of smaller glasses, researchers noted the increase likely reflects changes in factors including price, technology, societal wealth, and wine appreciation.
