The Swiss population drank 7.9 litres of pure alcohol per person in 2016, down from 8.1 litres the previous year and the lowest amount since the Second World War, the federal alcohol regulator (EAV) said on Thursday.
The figures show a continuation of a long-term trend towards drinking less alcohol, the body said.
In terms of pure alcohol, wine made up half of the total, followed by beer, spirits and cider.
