Starting April 20, Pepsi will sell cans of Pepsi Throwback and Mountain Dew Throwback, which will be made with real sugar instead of HFCS. According to an email exchange today with Pepsi-Cola rep Nicole Bradley (inspired by Serious Eaters' questions): "Both products will be offered at the same price as regular Pepsi and regular Mountain Dew." The drinks will only be available until June 13.
Around the same time, Coca-Cola usually rolls out limited-edition Kosher for Passover Coke, also made with real sugar since observant Jews cannot have corn products, hence no HFCS. Many non-Jews celebrate the product as well, believing the sugar version is superior (whether for taste or health reasons).
