Tradition since 1981
Excerpts from a 1/4/09 Parade magazine article by Martin Lindstrom
Some people believe that squeezing a lime into a Corona beer is a time-honored Mexican custom that came about to enhance the beer's taste. Others maintain that the ritual derives from an ancient Meso-American practice designed to combat germs, with the lime's acidity destroying bacteria.
The truth?
The Corona-and-lime ritual dates back only to 1981, when, reportedly on a bet with his buddy, a bartender popped a lime wedge into the neck of a Corona to see if he could start a trend.
This simple act, which caught on like wildfire, is generally credited with helping Corona overtake Heineken as the best-selling imported beer in the U.S. Market.
