The kind of beer also matters. I was never much of a beer drinker, but during my university days, there was one beer that I really liked: Het Kanon, a heavy beer with 11.6% alcohol, sold in .45l bottles. That is really not comparable to drinking a regular beer. Later they reduced the bottle size to the more common 0.33l. Probably for safety reasons.
