Naturalistic observations of beer drinking among college students.

The beer drinking behaviour of 308 university students was observed in several bar and party settings. The following relationships were found: (a) males drinking beer in bars consumed 0.92 oz per min; (b) females drank less beer than males; and stayed in a bar for a longer time period; (c) patrons drank significantly more beer when drinking in groups and when purchasing beer in pitchers versus cups or bottles; and (d) intervals between party arrival and first drink and between party departure and last drink varied inversely with blood alcohol concentration.
