>I question these numbers. 4.76 gal = 18000ml of alcohol.

Others have pointed out that the figures for NH are distorted by residents from MA and elsewhere crossing into NH to buy alcohol.

The nationwide average of 2.35 gallons is more interesting though. That's 8.9 litres per person, and Wikipedia says that's not very much by European standards. Many European countries average over 12 litres per person.

Even 12 litres seems a lot to me. A typical bottle of wine (750ml, 12-13% abv) has ~100ml of alcohol, so that's 120 bottles of wine per year or one every 3 days. Or with your 350ml 5% beer, that's 17.5ml of alcohol per can, so that's nearly 700 cans per year, or 13 cans per week. To my mind these are high as averages. But I guess the distribution has a long, heavy tail. I imagine that if we looked at the median or the mode, the numbers would be more relatable.
