From the Austin-American Statesman:
Overall wine drinking in the U.S. rose 3.2 percent in 2007 to 292.1 million 9-liter cases, according to the Beverage Information Group.
“If wine continues to grow at these levels, the U.S. will surpass both Italy and France to become both the largest wine market and biggest wine importer in the world by the end of the decade,” says Eric Schmidt, manager of information services for the Norwalk, Conn.-based Beverage Information Group
I did some math on this and 292.1 million 9-liter cases amount to 2,628,900,000 or 2.6 billion liters of wine. That equals 694,481,905 gal. of wine. Drink up America!
