Every spring, something subtle happens in the world of Coca-Cola that many shoppers never notice. For a short period leading up to Passover, certain bottling plants make a temporary change to one of the world’s most recognizable beverages. Instead of using high-fructose corn syrup, they produce Coca-Cola with cane sugar and place it in bottles marked with distinctive yellow caps. To the average customer, it may look like a simple packaging variation, but for many Jewish families, that small yellow cap carries deep religious significance.

During Passover, many observant Jews avoid foods containing certain grains and ingredients, including corn-derived products, depending on their traditions and customs. To meet kosher-for-Passover requirements, Coca-Cola works with rabbinic authorities to modify its recipe, ensure strict supervision throughout production, and certify that the finished product complies with the dietary guidelines observed during the holiday. The familiar red label remains, but the yellow cap quietly signals that the beverage is suitable for Passover celebrations.
