This was a randomised four-period crossover (i.e., multiple-treatment reversal) trial to estimate the impact of serving lager, ale and cider in straight-sided glasses on alcohol consumption in public houses and bars. Twenty-four bars in the UK took part. All participating venues completed two intervention periods (serving draught beer in straight-sided glasses) and two control periods (serving draught beer in the venue’s usual glasses), lasting a total of 8 weeks. The primary outcome was the mean volume (in litres) of draught lager, ale and cider (combined) sold weekly, which was compared between intervention and control periods.
