I feel bad for Britain and Spain. Taxes suck.
the data in the graph is lollably wrong and/or poorly defined. i lived in spain and purchased beer for about $0.80-1.50 us per liter from grocery stores, much cheaper than in the us.
i assume they are using some sort of a serving size adjusted price of beer in a bar, but they don't account for the fact that you frequently (normally) get a tapa included in the price of your beer in a spanish bar.
at any rate, us taxes on beer and wine are much higher than are spanish taxes.
