Sure but for Snapple, it’s kosher certified. So the company went through the trouble to get it approved. I do agree that tea is probably easier to get certified, but it takes extra effort to get that status.
I feel the same about "extra effort". When I lived in New York City, many vegetarian restaurants would go out of their way to get kosher and halal certified (by conservative clerics). The owners would prominantly display the certificate at the entrance, plus the menu would share the same information. In my view it was two things: (1) virtue signalling (fine by me), and (2) appeal to a more customers who might not "naturally" be vegetarian. I knew many Orthodox Jews at my office. If their favourite Jewish Kosher lunch/dinner place was closed, they would check for kosher veg options.
This is a good point too. Kosher and Halal have an appeal beyond just the religious. The standards for those certifications also points to a certain quality you might not otherwise get.
It’s still not the case that Snapple started off with something kosher to grab the market share. It just happens that they had a product that is easy to certify. The effort was likely small compared to the advertising benefit.
Right, but that's my point. If I were to launch a new product and I had the choice between ingredient A and ingredient B, and ingredient A meant I could get an easy kosher certificate, why not choose A?
