Marking for Slovenia is wrong. I do have statistical data from our statistical agency and it is not even close: 8.5l/person/year of vine and 26.5/person/year of beer (including non-alcohol).
Arguably, vine has higher alcohol content (~11.5%) compared to beer (~4.9%), but even even if we look at "alcohol consumed from wine/beer per person per year", we get 0,9775L from vine and 1,2985 from beer.
These findings are in agreement with my intuition based on me seeing what people drink.
