Discuss Don'tReallyCare's answer to: How much alcohol can one drink in 2hours?

Depending on gender, height, weight, stomach contents and other factors, people can usually consume about one standard drink of alcohol per hour without a significant rise in blood alcohol concentration (BAC).

A standard drink is a 12 oz serving of beer, a five oz serving of dinner wine, or a shot (1 & 1/2 oz) of distilled spirits (gin, tequila, rum, whiskey, etc.)
