We often think that 'small is good' and those small portions help us keep over indulgence at bay.Contrary to this belief scientists have found that people pour 20-30% more alcohol into short , wide glasses than into tall, narrow ones of the same volume, but they wrongly believe that tall glasses hold more. The study finds mention in BMJ.
This trend is not limited to general public but seasoned and professional bartenders do the same mistake or so to call it.
The study involved 198 college students and 86 bartenders from a large city in the United States. The experiment involved practice for the subjects. Thereafter half the students were given tall, slender 355 ml glasses and half were given short, wide 355 ml glasses. They were then instructed to pour a standard 'shot' of alcohol (1.5 ounces, 44.3 ml) for four mixed drinks (vodka tonic, rum and Coke, whiskey on the rocks, and gin and tonic) into the glasses. The bartenders were asked to do the same thing with or without instructions.
What was the result determined the outcome of the study. Both students and bartenders poured more into short, wide glasses than into tall, slender glasses.
The general mistakes were that students with practice reduced the tendency to over pour into tall glasses, but not into short, wide glasses.
Even bartenders poured 20.5% more into short, wide glasses than tall, slender ones.
