There are some countries (Germany comes to mind) where the average person drinks well over two beers per day, and throughout the day. Whether distrust of the public water supply is an excuse or a valid reason I don't know, but it was a factor as I recall.
Average per capita consumption of beer in Germany is at 106 liters/year. That's 225 pints. The same relationship holds true as in the US. There is a sizeable group of consumers that don't drink at all or only a handful of drinks/year, a wide group that has 1-3 drinks/week and a small group that accounts for the majority of alcohol sales and is in the 15-75 drinks/week range.
