Norwegians drink less than the citizens of other European countries. According to the health authorities, you’d have to look to Muslim countries to find a lower consumption.
In 2006 Norway had the lowest sale of alcohol per capita among 20 countries in Western and Central Europe. We bought 4,9 liters of pure alcohol. The Czechs bought 12 liters.
12 liters of pure alcohol translates as about 240 liters of beer. For every man, woman and child.
The volume of beer sold in Norway is about the same today as in 1980.
