Wine and its carbon footprint

Are you a wine-sipping hippie? (like me?)

Perhaps you'd be interested in the carbon foot print of your wine, as researched by Dr. Vino. The really interesting part is the wine-carbon line that runs down the US:

There’s a “green line” that runs down the middle of Ohio. For points to the West of that line, it is more carbon efficient to consume wine trucked from California. To the East of that line, it’s more efficient to consume the same sized bottle of wine from Bordeaux, which has had benefited from the efficiencies of container shipping, followed by a shorter truck trip. In the event that a carbon tax were ever imposed, it would thus have a decidedly un-nationalistic impact.

I'm going to have to add a few bottles of Bordeaux wines next time I'm out shopping.
