Kosher Coca-Cola, specially formulated for Jewish people to drink during Passover, has become a surprise best seller.

But it is not just Jews who are snapping up the sugar sweetened beverage, many cola-fans think it tastes better then the normal drink.

Around Passover time Coca-Cola uses sugar to sweeten their drinks rather than the cheaper fructose corn syrup which Jewish people are banned from consuming.

This is actually the traditional way Coca-Cola was sweetened before the introduction of FCS, explaining why some people claim the flavor reminds them of their youth.

In turn, this could explain the number of 30-somethings who are currently sat on street corners drinking Kosher-cola, eating sweets and playing with yo-yos.
