The Mason Dixon Wine
Though I don’t typically select my wine based on its carbon intensity, I found this study by Dr. Vino pretty interesting.
Tyler Colman, a PhD and wine blogger, examined the carbon footprint of wine and found that a “green” line exists, as shown above. For all states West of the line, it is more carbon efficient to consume wine trucked from California. For all states East of the line, it is more efficient to consumer wine bottled from France. Though a Bordeaux comes from a different continent, efficiencies in container shipping and shorter truck routes make it more efficient than trucking wine from Napa across the United States.
