Why Coca-Cola Bottles Get Yellow Caps Every Year

Coca-Cola has been releasing bottles with yellow caps for a limited time every year, but many people are only just realizing why.

The company's history dates back to its founding in May 1886 by John Pemberton, who marketed it as a 'temperance drink' after the prohibition legislation was passed in the United States. Initially, Coca-Cola contained real cane sugar, which was later replaced with corn syrup in the 1980s.

However, for those observing Passover, a Jewish holiday that lasts eight days and involves restrictions on certain ingredients, Coca-Cola releases bottles made with real cane sugar again, symbolized by the yellow cap. This special edition is only available during this time period due to Kosher dietary laws prohibiting corn syrup consumption.
