If you have ever spotted a Coca Cola bottle with a yellow cap and wondered if it was a special flavour, you are not alone. The label looks familiar, the drink is not marked as Diet or Zero, and yet that tiny splash of colour suggests something is different. Recently, the detail went viral online, with people sharing photos and asking the same question. As it turns out, the cap is not a random design choice at all.
The yellow cap is used for a specific seasonal run of classic Coca Cola made to meet kosher requirements for Passover. Passover is a major Jewish holiday that commemorates the Israelites’ liberation from slavery in Egypt. During this time, many people follow dietary rules that restrict certain foods and ingredients. One of the key issues for this story is corn.
In many places, regular Coca Cola is sweetened with high fructose corn syrup. Because corn is avoided by many during Passover, that version would not fit the holiday’s kosher guidelines for those consumers. That is why the yellow cap matters. It signals a version produced without corn derived sweeteners, so shoppers can quickly spot what they are looking for.

On social media, creators like Moses & Zippora explained the difference in a short, shareable way that helped the message spread. Another account, SnackEatingSnacks, posted an annual reminder that the yellow cap bottles are back for the year, encouraging people to grab them while they can. For many viewers, it was the first time they had heard that Coca Cola makes a Passover friendly version that can also taste a little different. The conversation quickly turned from curiosity to a kind of seasonal scavenger hunt.
The funniest part is how many people admitted they had walked past yellow caps for years without knowing what they meant. Commenters shared their surprise, with some saying they only learned about it this year. Others chimed in to confirm that the cap is essentially a quick marker for Passover certification. A small change in packaging ended up revealing a whole layer of tradition and planning behind a product most of us take for granted.
