Eleven non-alcoholic subjects gave written informed consent. Seven men (age 23-52) and four women (age 26-44) were hydrostatically weighed to determine their % body fat and lean body weight. Female subjects on average had a higher % body fat 23.5% (range 18.6-30.0%) than males 16.9% (range 7.5-30.2%). Each subject fasted for at least 10 hrs. then received an oral dose of alcohol at 1.23 g/kg of lean body weight to achieve the intended alcohol concentration of approximately 0.11. On day one beer, containing approximately 5% ethanol by volume, was consumed and on day two 101 proof whiskey mixed with a carbonated beverage was consumed. The drinks were consumed over 2 hr. and 45 min. in three 45-min. drinking periods. Each drinking period was followed by a 15-min. deprivation period and breath alcohol measurements were conducted. After drinking ended, testing continued in 20-min. intervals until each subject's alcohol concentration returned to 0.000. All alcohol analyses were conducted on the Intoxilyzer 5000® and reported as g/210 L. While there were significant individual subject differences in both women and men in peak alcohol concentrations between beer and whiskey, the differences between the average peak alcohol concentrations between women and men, and beer and whiskey were insignificant.
