Berkshire Hathaway billionaire Warren Buffett famously consumes five cans of Coke a day.
However, Markets Insider reports Buffett drank Pepsi for nearly 50 years.
He only switched sodas because an old neighbor intervened.
Don Keough was a coffee salesman who lived across the street from Buffett in Omaha.
Keough eventually became Coca-Cola’s president and operating chief.
After learning that Buffett drank Pepsi-Cola Cherry, Keough sent him samples of the upcoming Cherry Coke.
