In the year 2002, 595 million gallons of wine were sold in the United States, totaling about $21.1 billion in consumer spending. This translates to more than 2 gallons (7.6 L) of wine consumed per resident. Many Americans enjoy wine with a meal or have wine at social functions. It has even been reported that a glass of red wine per day can reduce your risk of heart attack and stroke.
