10 litres alcohol is about 100 bottles of wine a year (exactly 100 at 13.33% alcohol content).

I drink a lot of wine, but 1 full bottle is too much to have regularly. A half bottle - two generous glasses - is more reasonable, but you'll still feel it the next day. And 10 litres of alcohol puts you at 8 generous glasses a week.

I reckon this is still quite a lot of alcohol.
