Close to 13 million pints are sold worldwide on St. Patrick's Day. While its popularity spikes on the holiday, Guinness is still a very popular global beer brand, with an average of about 5.5 million pints of Guinness being sold on any given day of the year.

Though Guinness is popular, global interest in this iconic Irish beer brand more than doubles on St. Patrick's Day, a holiday that is strongly tied to popular conceptions of Ireland. The association of Guinness with St. Patrick's Day may have been a product of Irish immigrants bringing their traditions, customs and favored beverages across the Atlantic to their new homes in the United States.
