  • Wine contains around 12% of pure alcohol per volume 2 so that one liter of wine contains 0.12 liters of pure alcohol. The global average of 6.4 liters of pure alcohol per person per year therefore equals 53 bottles of wine per person older than 15 (6.4l / 0.12l). Or to make it more memorable, around 1 liter of wine per week.
