In America Cinco de Mayo has evolved to become one of the country’s largest drinking holidays. In 2013, over $600 million dollars worth of beer was sold, according to Nielsen data, which is more beer than is sold for St. Patrick’s Day or the Super Bowl, two holidays where beer consumption is the primary focal point. And most of that beer is Mexican in origin, which has also meant that the Mexican beer sector, thanks to Cinco de Mayo, has continued to grow and thrive north of the border, experiencing the best sector growth in the American market according to EuroMonitor data, second only to the rapid growth of American craft beer.

Suffice it to say, Cinco de Mayo is a behemoth when it comes to selling booze, but how did a holiday that isn’t really even celebrated in Mexico – Mother’s Day, which occurs around the same time, is a much bigger deal – become not only the most powerful U.S. holiday when it comes to selling alcohol, but also the only connection most Americans have to our largest immigrant group? You can thank Texas distributors of Corona in the 1980s.

Yet another completely made up “holiday” created in the service of marketing.
