It's been going down since 2007, number for 2020 was 9,2 liters of 100% alcohol per +15 year citizen. The number for 1996 on that list contains only officially purchased alcohol - the actual number was 10,6 liters or so.

I wouldn't be surprised if Finns drank more than Spanish or Greeks. We drink mostly at home, but not with meals. Half of the consumption is beer, mostly on weekends and especially during the summer months.

But mainly personal anecdotal evidence from my adventure with a group of Spanish and Italian students in Madrid some 20 years ago: at the end of a long night  two of them told me they were really impressed that I showed no signs of being drunk after all the alcohol I had consumed and that they would be probably dead. I was a bit embarrassed since I indeed wasn't that drunk and merely felt just properly warmed up and all of a sudden felt like an old boozer :-)
